Converting CO2 to Solid Carbon Nanofibers

Tandem electrocatalytic-thermocatalytic conversion could help offset emissions of potent greenhouse gas by locking carbon away in a useful material.

Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and Columbia University have developed a way to convert carbon dioxide (CO2), a potent greenhouse gas, into carbon nanofibers, materials with a wide range of unique properties and many potential long-term uses. Their strategy uses tandem electrochemical and thermochemical reactions run at relatively low temperatures and ambient pressure. As the scientists describe in the journal Nature Catalysis, this approach could successfully lock carbon away in a useful solid form to offset or even achieve negative carbon emissions.

Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and Columbia University have developed a way to convert carbon dioxide (CO2), a potent greenhouse gas, into carbon nanofibers, materials with a wide range of unique properties and many potential long-term uses. Their strategy uses tandem electrochemical and thermochemical reactions run at relatively low temperatures and ambient pressure. As the scientists describe in the journal Nature Catalysis, this approach could successfully lock carbon away in a useful solid form to offset or even achieve negative carbon emissions.

“You can put the carbon nanofibers into cement to strengthen the cement,” said Jingguang Chen, a professor of chemical engineering at Columbia with a joint appointment at Brookhaven Lab who led the research. “That would lock the carbon away in concrete for at least 50 years, potentially longer. By then, the world should be shifted to primarily renewable energy sources that don’t emit carbon.”

As a bonus, the process also produces hydrogen gas (H2), a promising alternative fuel that, when used, creates zero emissions.

Capturing or converting carbon?
The idea of capturing CO2 or converting it to other materials to combat climate change is not new. But simply storing CO2 gas can lead to leaks. And many CO2 conversions produce carbon-based chemicals or fuels that are used right away, which releases CO2 right back into the atmosphere.

“The novelty of this work is that we are trying to convert CO2 into something that is value-added but in a solid, useful form,” Chen said.

Such solid carbon materials—including carbon nanotubes and nanofibers with dimensions measuring billionths of a meter—have many appealing properties, including strength and thermal and electrical conductivity. But it’s no simple matter to extract carbon from carbon dioxide and get it to assemble into these fine-scale structures. One direct, heat-driven process requires temperatures in excess of 1,000 degrees Celsius.

“It’s very unrealistic for large-scale CO2 mitigation,” Chen said. “In contrast, we found a process that can occur at about 400 degrees Celsius, which is a much more practical, industrially achievable temperature.”

The tandem two-step
The trick was to break the reaction into stages and to use two different types of catalysts—materials that make it easier for molecules to come together and react.

“If you decouple the reaction into several sub-reaction steps you can consider using different kinds of energy input and catalysts to make each part of the reaction work,” said Brookhaven Lab and Columbia research scientist Zhenhua Xie, lead author on the paper.

The scientists started by realizing that carbon monoxide (CO) is a much better starting material than CO2 for making carbon nanofibers (CNF). Then they backtracked to find the most efficient way to generate CO from CO2.

Earlier work from their group steered them to use a commercially available electrocatalyst made of palladium supported on carbon. Electrocatalysts drive chemical reactions using an electric current. In the presence of flowing electrons and protons, the catalyst splits both CO2 and water (H2O) into CO and H2.

For the second step, the scientists turned to a heat-activated thermocatalyst made of an iron-cobalt alloy. It operates at temperatures around 400 degrees Celsius, significantly milder than a direct CO2-to-CNF conversion would require. They also discovered that adding a bit of extra metallic cobalt greatly enhances the formation of the carbon nanofibers.

“By coupling electrocatalysis and thermocatalysis, we are using this tandem process to achieve things that cannot be achieved by either process alone,” Chen said.

Catalyst characterization
To discover the details of how these catalysts operate, the scientists conducted a wide range of experiments. These included computational modeling studies, physical and chemical characterization studies at Brookhaven Lab’s National Synchrotron Light Source II (NSLS-II)—using the Quick X-ray Absorption and Scattering (QAS) and Inner-Shell Spectroscopy (ISS) beamlines—and microscopic imaging at the Electron Microscopy facility at the Lab’s Center for Functional Nanomaterials (CFN).

On the modeling front, the scientists used “density functional theory” (DFT) calculations to analyze the atomic arrangements and other characteristics of the catalysts when interacting with the active chemical environment.

“We are looking at the structures to determine what are the stable phases of the catalyst under reaction conditions,” explained study co-author Ping Liu of Brookhaven’s Chemistry Division who led these calculations. “We are looking at active sites and how these sites are bonding with the reaction intermediates. By determining the barriers, or transition states, from one step to another, we learn exactly how the catalyst is functioning during the reaction.”

X-ray diffraction and x-ray absorption experiments at NSLS-II tracked how the catalysts change physically and chemically during the reactions. For example, synchrotron x-rays revealed how the presence of electric current transforms metallic palladium in the catalyst into palladium hydride, a metal that is key to producing both H2 and CO in the first reaction stage.

For the second stage, “We wanted to know what’s the structure of the iron-cobalt system under reaction conditions and how to optimize the iron-cobalt catalyst,” Xie said. The x-ray experiments confirmed that both an alloy of iron and cobalt plus some extra metallic cobalt are present and needed to convert CO to carbon nanofibers.

“The two work together sequentially,” said Liu, whose DFT calculations helped explain the process.

“According to our study, the cobalt-iron sites in the alloy help to break the C-O bonds of carbon monoxide. That makes atomic carbon available to serve as the source for building carbon nanofibers. Then the extra cobalt is there to facilitate the formation of the C-C bonds that link up the carbon atoms,” she explained.

Recycle-ready, carbon-negative
“Transmission electron microscopy (TEM) analysis conducted at CFN revealed the morphologies, crystal structures, and elemental distributions within the carbon nanofibers both with and without catalysts,” said CFN scientist and study co-author Sooyeon Hwang.

The images show that, as the carbon nanofibers grow, the catalyst gets pushed up and away from the surface. That makes it easy to recycle the catalytic metal, Chen said.

“We use acid to leach the metal out without destroying the carbon nanofiber so we can concentrate the metals and recycle them to be used as a catalyst again,” he said.

This ease of catalyst recycling, commercial availability of the catalysts, and relatively mild reaction conditions for the second reaction all contribute to a favorable assessment of the energy and other costs associated with the process, the researchers said.

“For practical applications, both are really important—the CO2 footprint analysis and the recyclability of the catalyst,” said Chen. “Our technical results and these other analyses show that this tandem strategy opens a door for decarbonizing CO2 into valuable solid carbon products while producing renewable H2.”

If these processes are driven by renewable energy, the results would be truly carbon-negative, opening new opportunities for CO2 mitigation.

Glacier protection rethought: Nonwovens made of cellulosic fibers

Protection for snow and ice: Cellulosic LENZING™ fibers offer solution for preservation of glacier mass

In field trials on Austrian glaciers, nonwovens made of cellulosic LENZING™ fibers are being used to cover glacier mass. They are showing promising results and offer a sustainable solution for glacier protection. Nonwovens containing fossil-based synthetic fibers might cause negative environmental consequences such as microplastics on glaciers.

Protection for snow and ice: Cellulosic LENZING™ fibers offer solution for preservation of glacier mass

In field trials on Austrian glaciers, nonwovens made of cellulosic LENZING™ fibers are being used to cover glacier mass. They are showing promising results and offer a sustainable solution for glacier protection. Nonwovens containing fossil-based synthetic fibers might cause negative environmental consequences such as microplastics on glaciers.

Geotextiles are already widely used to protect snow and ice on glaciers from melting. The use of nonwovens made from cellulosic LENZING™ fibers is now achieving a sustainable turnaround. Geotextiles show great success in Austria in protecting glaciers, which are highly endangered by global warming. By covering glacier mass, its melting is slowed down and mitigated. So far, the nonwovens used to protect glaciers are usually made of fossil-based synthetic fibers. The problem with that might occur as microplastics left behind after the summer flow down into the valley and can enter the food chain through small organisms and animals.

Sustainability from production to reuse
An innovative and sustainable solution for the protection of snow and ice is now possible with the help of nonwovens made of cellulosic LENZING™ fibers. "LENZING™ fibers are derived from renewable, responsibly managed wood sources and are produced in an environmentally responsible process. Thanks to their botanic origin, they have the ability to break down, returning into nature after use" explains Berndt Köll, Business & Innovation Manager at Lenzing.

In a field trial on the Stubai Glacier, the covering of a small area with the new material containing cellulosic LENZING™ fibers was tested for the first time. The result was convincing: 4 meters of ice mass could be saved from melting. Due to its success, the project is now being expanded. In 2023 field tests started in all Austrian glaciers, which are used for tourism.

"We are pleased with the positive results and see the project as a sustainable solution for glacier protection - not only in Austria, but beyond national borders," Berndt Köll continues. There should also be a possibility to explore for recycling after the nonwovens are used: These geotextiles can be recycled and ultimately used to make yarn for textile products.

Awarded with the Swiss BIO TOP
The sustainable glacier protection and its results also convinced the jury of industry experts of the BIO TOP, a major award for wood and material innovations in Switzerland. With this award innovative projects in the field of bio-based woods and materials are promoted and supported. At the award ceremony on September 20, 2023, Geotextiles containing LENZING™ fibers were honored with the award for its solution.

Pyrolysis processes promise sustainable recycling of fiber composites

Wind turbines typically operate for 20 to 30 years before they are undergoing dismantling and recycling. However, the recycling of fiber composites, especially from the thick-walled rotor blade parts, has been inadequate until now. The prevailing methods involve thermal or mechanical recycling. For a sustainable and holistic recycling process, a research consortium led by Fraunhofer IFAM is pooling their expertise to recover the fibers through pyrolysis. Subsequent surface treatment and quality testing of the recyclates allow for them to be used again in industry.

Wind turbines typically operate for 20 to 30 years before they are undergoing dismantling and recycling. However, the recycling of fiber composites, especially from the thick-walled rotor blade parts, has been inadequate until now. The prevailing methods involve thermal or mechanical recycling. For a sustainable and holistic recycling process, a research consortium led by Fraunhofer IFAM is pooling their expertise to recover the fibers through pyrolysis. Subsequent surface treatment and quality testing of the recyclates allow for them to be used again in industry.

Today, the vast majority of wind turbines can already be recycled cleanly. In the case of rotor blades, however, recycling is only just beginning. Due to the 20-year operation period and the installation rates, the blade volume for recycling will be increasing in the coming years and decades. In 2000, for example, around 6,000 wind turbines were erected in Germany, which now need to be fed into a sustainable recycling process. In 2022, about 30,000 onshore and offshore wind turbines with a capacity of 65 gigawatts were in operation in Germany alone.

As wind energy is the most important cornerstone for a climate-neutral power supply, the German government has set itself the goal of further increasing its wind energy capacity by 2030 by installing larger and more modern turbines. Rotor blades will become longer, the proportion of carbon fibers used will continue to increase - and so will the amount of waste. In addition, the existing material mix in rotor blades is expected to increase in the future and precise knowledge of the structure of the components will become even more important for recycling. This underscores the urgency of developing sustainable processing methods, especially for recycling the thick-walled fiber composites in the rotor blades.

Economic and ecological recycling solution for fiber composites on the horizon
Rotor blades of wind turbines currently up for recycling consist of more than 85 percent of glass- and carbon-fiber-reinforced thermosets (GFRP/CFRP). A large proportion of these materials is found in the flange and root area and within the fiber-reinforced straps as thick-walled laminates with a wall thicknesses of up to 150 mm. Research into high-quality material fiber recycling as continuous fibers is of particular importance, not only because of the energy required for carbon fiber production. This is where the project "Pyrolysis of thick-walled fiber composites as a key innovation in the recycling process for wind turbine rotor blades" – "RE SORT" for short – funded by the German Federal Ministry of Economics and Climate Protection comes in. The aim of the project team is the complete recycling by means of pyrolysis.

A prerequisite for high-quality recycling of fiber composites is the separation of the fibers from the mostly thermoset matrix. Although pyrolysis is a suitable process for this purpose, it has not yet gained widespread adoption. Within the project, the project partners are therefore investigating and developing pyrolysis technologies that make the recycling of thick-walled fiber composite structures economically feasible and are technically different from the recycling processes commonly used for fiber composites today. Both quasi-continuous batch and microwave pyrolysis are being considered.

Batch pyrolysis, which is being developed within the project, is a pyrolysis process in which the thermoset matrix of thick fiber composite components is slowly decomposed into oily and especially gaseous hydrocarbon compounds by external heating. In microwave pyrolysis, energy is supplied by the absorption of microwave radiation, resulting in internal rapid heat generation. Quasi-continuous batch pyrolysis as well as microwave pyrolysis allow the separation of pyrolysis gases or oils. The planned continuous microwave pyrolysis also allows for the fibers to be preserved and reused in their full length.

How the circular economy succeeds - holistic utilization of the recycled products obtained
In the next step, the surfaces of the recovered recycled fibers are prepared by means of atmospheric plasmas and wet-chemical coatings to ensure their suitability for reuse in industrial applications. Finally, strength tests can be used to decide whether the recycled fibers will be used again in the wind energy industry or, for example, in the automotive or sporting goods sectors.

The pyrolysis oils and pyrolysis gases obtained in batch and microwave pyrolysis are evaluated with respect to their usability as raw materials for polymer synthesis (pyrolysis oils) or as energy sources for energy use in combined heat and power (CHP) plants (pyrolysis gases).

Both quasi-continuous batch pyrolysis and continuous-flow microwave pyrolysis promise economical operation and a significant reduction in the environmental footprint of wind energy. Therefore, the chances for a technical implementation and utilization of the project results are very good, so that this project can make a decisive contribution to the achievement of the sustainability and climate goals of the German Federal Government.

Checking clothing using a smartphone, AI and infrared spectroscopy

Researchers at Fraunhofer have developed an ultra-compact near-infrared spectrometer suitable for recognizing and analyzing textiles. Mixed fabrics can also be reliably identified through the combination of imaging, special AI (artificial intelligence) algorithms and spectroscopy. The technology could be used to optimize recycling old clothing, so old apparel could be sorted according to type. A highly miniaturized version of the system can even fit into a smartphone. This could lead to a host of new applications for end-users in everyday life — from checking clothes when out shopping to detecting counterfeits.

This could lead to a host of new applications for end-users in everyday life — from checking clothes when out shopping to detecting counterfeits.

Infrared spectrometers are powerful measuring instruments when it comes to non-destructive analysis of organic materials. The Fraunhofer Institute for Photonic Microsystems IPMS in Dresden has recently developed a spectral analyzer system that recognizes and analyzes textile fabrics. The system can also reliably recognize mixed fabrics. Possible applications range from checking fabrics when out shopping to cleaning garments correctly, and even sustainable, sorted recycling. The spectrometer is so tiny, it can be integrated into a smartphone.

Researchers at Fraunhofer rely on near-infrared (NIR) spectroscopy to achieve the required reliability and accuracy when identifying textiles. The system works for wavelengths between 950 and 1900 nanometers, which is close to the visible spectrum. Advantages of near-infrared technology include being easy to use and having a wide range of applications. “We combine NIR spectroscopy with imaging and AI to achieve higher accuracy when recognizing and analyzing objects,” explains Dr. Heinrich Grüger, research scientist in the Sensoric Micromodules department at Fraunhofer IPMS.

How textile analysis works
Firstly, a conventional camera module captures an image of the garment. The AI selects a specific point from the fabric’s image data to be examined by the spectral analyzer module. Light reflected from the fabric is captured by the spectrometer module. There, it passes through an entrance slit, is transformed into parallel light beams using a collimating mirror and projected onto a grating using a scanning mirror. Depending on the angle of incidence and exit, the grating splits the light beams into different wavelengths. Light reflected from the grating is directed by the scanner mirror to a detector which captures the light as an electrical signal. An A/D converter then digitizes these signals, which are subsequently analyzed in the signal processor. The resulting spectrometric profile for the textile fabric reveals which fibers it is made from by comparing to a reference database.“ The optical resolution is 10 nanometers. This high resolution means the NIR spectrometer can also use AI to identify mixed fabrics such as items of clothing made from polyester and cotton,” says Grüger. Measuring just 10 mm × 10 mm and being 6.5 mm thick, the system is so compact it could easily be integrated into a standard smartphone.

Recycling old clothing
Grüger sees an important application for the AI-controlled spectrometer when it comes to recycling. According to the Federal Statistical Office of Germany, approximately 176,200 tons of textile and clothing waste was collected from private homes in Germany in 2021. NIR spectroscopy could improve recycling efficiency and reduce the mountain of old clothing. This would enable companies that recycle old clothing to sort it more efficiently and faster. Textiles that are still in one piece, for instance, go to the second-hand trade. Damaged textiles are sorted for recycling, and the fibers they are made from, such as linen, silk, cotton or lyocell, can be reused. Severely soiled textiles would be incinerated or processed into insulation mats, for example. Spectroscopic identifies and sorts textiles more accurately and much faster than a human can.

If NIR spectroscopy was to be integrated into a smartphone, end-users might also benefit from the Fraunhofer institute’s technology. When buying clothes, a quick check with a smartphone reveals whether that expensive silk scarf is genuinely made from silk, or whether that exclusive dress from the fashion label is not instead a counterfeit, exposed through an alternative mix of fabrics. And should the label with the cleaning instructions no longer be legible, the smartphone has a textile scanner to identify the fabric and so determine the appropriate wash cycle.

Food check and dermatology
Researchers at Fraunhofer IPMS can even envisage applications beyond the textile industry. Smartphones fitted with spectrometers might be used to provide information about the quality of groceries such as fruit and vegetables when out shopping. The technology might conceivably also be used to examine skin. A quick scan with the cell phone spectrometer could identify particularly dry or greasy patches. Perhaps applications in medical diagnostics might even be conceivable — examining patches of skin where a melanoma is suspected, for example — but this would need professional involvement too.

Heimtextil Trends 24/25: New Sensitivity

Under the theme "New Sensitivity", textile transformation is the focus of Heimtextil Trends 24/25. Three approaches show ways to a more sensitive world of textiles: the plant-based production of textiles, the support of textile cycles by technology and the bioengineered use of natural ingredients. In addition, Future Materials curates regenerative materials and designs.
 
After last year's focus on circular solutions, Heimtextil Trends 24/25 will once again shed light on transformative textile innovations.
Under the title "New Sensitivity," the focus is on innovations and changes in the composition of textiles, in addition to aesthetic aspects. "In this context, sensitivity means considering the impact on the environment when making a decision or creating a product. Understanding how natural ecosystems work and prioritising balance as the default are key," says Anja Bisgaard Gaede, Founder of SPOTT trends & business.

"In this context, sensitivity means considering the impact on the environment when making a decision or creating a product. Understanding how natural ecosystems work and prioritising balance as the default are key," says Anja Bisgaard Gaede, Founder of SPOTT trends & business.

How does New Sensitivity translate into something concrete in the lifestyle industry, and what does having a sensitive approach to design and products mean? Also the adoption of Artificial General Intelligence (AGI) is transforming current times. AGI has the potential to bring innovative solutions and help tackle significant challenges, also in the textile industry. However, AGI can have the opposite effect on society. AGI needs the mindset of New Sensitivity that helps simplify complexity, expand creativity, and find unseen solutions, also within the world of textiles.
     
"With Heimtextil Trends 24/25: New Sensitivity, we encourage the textile industry to approach the future with thoughtfulness and consideration. Specifically, we see this change in three different trends for a more sensitive world of textiles: biotechnical, plant-based and technological," Bisgaard Gaede continues.

Plant-based: textiles made from plant crops or plant by-products
Plant-based textiles mean that the fibres are derived from something that grows rather than being synthetically produced. The sustainable advantage of plant-based textiles is that their origin is natural and, therefore, more able to recirculate in existing ecosystems. They can be divided into two groups. The first group of textiles are made from plant crops. New resilient crops like cactus, hemp, abaca, seaweed, and rubber offer new sustainable textile solutions. Because of mechanical extraction, they can grow despite climate changes and require fewer chemicals in their development. The second group consists of textiles made of plant by-products which are leftover raw materials from production such as banana, olive, persimmon and hemp.

Technological: technology and technical solutions transforming textiles
Technology can support the transformation of textiles through the use of different methods: upcycling and recycling of textiles, textile construction, and textile design. Due to decades of production, textiles are now a material available in abundance. Developing technologies for recycling textile waste and methods for upcycling textiles increases the circular usage of existing textiles. Furthermore, old textile construction techniques also offer pathways to sustainable solutions: For instance, using knitting technology for furniture upholstery produces less fabric waste; alternatively, weaving technique allows the creation of several colours using only a few coloured yarns. Textile Design Thinking is another method that addresses critical issues such as energy usage and durability of natural fibres and enhances these through technological textile advancement.

Bio-engineered: engineered to enhance bio-degrading
To a certain degree, bio-engineered textiles represent a fusion of plant-based and technological textiles. Bio-engineering bridges nature and technology and transforms the way textiles are made. They can be divided into two directions: fully bio-engineered and bio-degradable textiles. In the production of fully bio-engineered textiles nature-inspired strategies are adopted. Instead of growing plants and extracting their fibres, textiles are made from the protein, carbohydrates, or bacteria in corn, grass, and cane sugar. Manufacturing involves a bio-molecular process that creates filaments which are made into yarn. The sustainable advantage of bio-engineered textiles is that they can have some of the same functionalities as synthetically produced textiles, while still being biodegradable because of their natural origin. Biodegradable fibres can be added to conventional textiles like polyester to enhance the conventional textiles’ ability to revert to materials found in nature and hence biodegrade in natural environments such as water or soil. Although not biodegrading completely, these bio-enhanced textiles will biodegrade up to 93 % compared to conventional textiles.

Heimtextil Trends 24/25: new colourways
A sensitive approach to colouring methods is expressed by a dynamic yet subtle colour palette created through natural pigments deriving from the earth, as traditional colouring processes are brought to the next level through innovative bioengineering technology. In pursuit of creating colours that evoke emotions in our senses while at the same time respecting our values in protecting the environment, we see colour bacteria growing pigments generating hues with great richness and depth.
               
This New Sensitivity includes acceptance of natural colour flows, as colours may fade with time or morph into new colourways. The colourways for Heimtextil Trends 24/25 were inspired by natural colours deriving from avocado seeds, algae, living bacteria, antique pigments such as raw sienna, and bio-engineered indigo and cochineal. The high black component in most colours allows for widespread application and a greater variety of combinations. The punchy saturated accents enhance our senses as they lift our spirits. In contrast, the grounding neutrals in different shades of grey, terra and even dark purple allow for calmness and tranquillity.

Future Materials: regenerative design
How are regenerative textiles and materials defined? Regenerative design is dedicated to developing holistic creative practices that restore or renew resources, have a positive impact on the environment, and encourage communities to thrive. For Heimtextil 2024, design futures consultancy FranklinTill is curating a global showcase of cutting-edge textiles and materials to illustrate the principles of regenerative design and recognize pioneering designers, producers and manufacturers who are at the forefront of regenerative design.
The Trend Space at Heimtextil in Frankfurt, Germany, January 9-12, 2023, will showcase these pioneering solutions in an inspiring way. In addition, Heimtextil Trends will offer visitors orientation and insights into the future of home and contract textiles in the form of workshops, lectures and other interactive formats.

Point of View: Let’s end fast fashion, Prof Minna Halme. Photo: Veera Konsti / Aalto University

Point of View: Let’s end fast fashion

Focusing on short-term profit isn’t sustainable. So what can we do to move in the right direction: favour resilience over efficiency in all industries.

We buy cheap products knowing we’ll need to replace them soon. We throw out used items rather than repairing or re-using them. Our employers plan in terms of financial quarters despite hoping to remain relevant and resilient longer-term. Even countries prioritise short-term economic output, focusing on gross domestic product (GDP) above any other indicator.

But does this way of living, working and weighing decisions make sense in the 21st century?

Our global obsession with economic short-term efficiency – and how to transform it – is a conundrum that Professor of Sustainability Management Minna Halme has been thinking about for most of her career. Even as a business school student, she felt flummoxed by how focused her classes were on short-term goals.

Even countries prioritise short-term economic output, focusing on gross domestic product (GDP) above any other indicator.

But does this way of living, working and weighing decisions make sense in the 21st century?

Our global obsession with economic short-term efficiency – and how to transform it – is a conundrum that Professor of Sustainability Management Minna Halme has been thinking about for most of her career. Even as a business school student, she felt flummoxed by how focused her classes were on short-term goals.

'It was about selling more, about maximising shareholder profits, about economic growth – but not really asking, Why? What's the purpose of all this?'

Halme says. 'Even 20-year-old me somehow just felt that this was strange.

'What are we trying to do here? Are we trying to create a better economy for all, or most, people? Whose lives are we trying to improve when we are selling more differently-packaged types of yoghurt or clothes that quickly become obsolete?'

Halme has devoted her career to studying these questions. Today, she is a thought leader in innovative business practices, with recognitions including serving on Finland's National Expert Panel for Sustainable Development and on the United Nation's Panel on Global Sustainability.

Her ultimate goal? Pioneering, researching and advocating for alternative ways of thinking that prioritise values like long-term economic sustainability and resilience – alternatives that she and other experts believe would provide more lasting, widespread benefit to all.

How traditional indicators have failed
One way in which our preference for economic efficiency shapes how we measure a country's overall well-being or status is GDP. This isn't the fault of the originator of the modern concept of GDP, who specifically warned against using it in this way in the 1930s.

'GDP was never meant to tell us about the wellbeing of the citizens of a country,' Halme says. Seventy-five years ago, however, it was easy to conflate the two. Many countries were more committed to redistributing their wealth among their citizens, and population surveys show that until the 1970s, GDP often correlated with general wellbeing.

But with the rise of increasingly heedless free-market capitalism, this became less the case – and GDP's shortcomings became all the more apparent. 'We are in a situation where the wealth distribution is more and more trickling up to those who already have capital. Those who don't have it are in declining economic positions,' Halme says. In fact, the richest 1% of the global population now own nearly half of the world's wealth.

Some governments, such as Finland's, do take indicators of environmental and social progress into account. 'But none is considered as important for decision-making as GDP,' Halme says – and GDP is also considered the arbiter of a government's success. It is that attitude that, through her work advising the Finnish government on sustainability practises as well as in her own research, Halme is trying to shift.

Where industries have failed
Our often-exclusive focus on the economy – and, in particular, on making profits as quickly and efficiently as possible – doesn’t provide a clear picture of how everyone in a society is faring. Worse yet, it has encouraged industries to act with a short-term view that makes for longer-term problems.

Fast fashion is one example. At the moment, supply chains for clothing – as for most other goods – are linear. Raw materials come from one place and are transformed step by step, usually at different factories around the world, using materials, energy and transport that are “cheap” because their high environmental costs aren’t included. They are ultimately purchased by a consumer, who wears the product temporarily before discarding it. To expand profit margins, the industry pushes fast-changing trends. A shocking amount of this clothing ends up in landfill – some of it before it's even been worn.

As the COVID lockdowns showed, this kind of linear supply system isn't resilient. Nor is it sustainable.

Currently, fashion is estimated to be the world's second most polluting industry, accounting for up to 10% of all greenhouse gas emissions. Aalto University researchers have reported that the industry produces more than 92 million tonnes of landfill waste per year. By 2030, that is expected to rise to 134 million tonnes.

Cutting fashion's carbon footprint isn't just good for the environment; it will help the longer-term prospects of the industry itself. 'With this kind of wrong thinking about efficiency, you're eroding the basis of our long-term resilience both for ecology and for society,' Halme says.

Getting out of this trap, she and other researchers say, requires a complete paradigm shift. 'It's really difficult to just tweak around the edges,' she says.

Towards resilience
For several years, Halme researched and studied ecological efficiency, looking at ways that businesses could make more products with a smaller environmental impact. But gradually she realised this wasn't the answer. Although businesses could innovate to have more efficient products and technologies, their absolute use of natural resource use kept growing.

'I began to think, "If not efficiency, then what?"' Halme says. She realised the answer was resilience: fostering ways for systems, including the environment, to continue and even regenerate in the future, rather than continuing to degrade them in the present.

The solution isn’t more of anything, even ‘sustainable’ materials. It’s less.

'The only way to fix fast fashion is to end it,' Halme and her co-authors write. This means designing clothes to last, business models that make reuse and repair more accessible, and prioritising upcycling. Recycling systems also need to be overhauled for when an item really is at the end of its life – particularly regarding blended synthetic fibres, which are difficult to separate and break down.

This would upend the current focus on short-term revenue above all else. And, says Halme, it is one more example of how we need better ways to measure the success of these industries, taking into account factors like resilience and sustainability – rather than just short-term profits.

And while individuals can make an impact, these changes ultimately have to be industry-led.

'Textiles are a good example, because if they break quickly, and if you don't have repair services nearby, or if the fabrics are of such lousy quality that it doesn't make any sense to repair them, then it's too much trouble for most people,' Halme says. 'So most solutions should come from the business side. And the attempt should be to make it both fashionable and easy for consumers to make ecologically and socially sustainable choices.'

What will it take?
The ultimate challenge, says Lauri Saarinen, Assistant Professor at the Aalto University Department of Industrial Engineering and Management, is how to shift towards a more sustainable model while keeping companies competitive. But he believes there are ways.

One option is to keep production local. 'If we compete with low-cost, offshore manufacturing by doing things more locally, and in a closed loop, then we get the double benefit of actually providing some local work and moving towards a more sustainable supply chain,' Saarinen says. For example, if clothing were produced closer to consumers, it would be easier to send garments back for repair or for brands to take back used items and resell them.

Local production is yet another example of the need to rethink how we measure societal success. After all, outsourcing and offshoring in favour of cheaper production may appear to cut costs in short term, but this is done at the expense of what Halme and other experts argue really matters – longer-term economic viability, resilience and sustainability.

Shifting towards this kind of thinking isn't easy. Still, Saarinen and Halme have seen promising signs.

In Finland, for example, Halme points to the start-up Menddie, which makes it easy and convenient to send items away for repairs or alterations. She also highlights the clothing and lifestyle brand Marimekko, which re-sells its used items in an online secondhand shop, and the Anna Ruohonen label, a made-to-measurecollection and customer on-demand concept which creates no excess garments.

It's these kinds of projects that Halme finds interesting – and that, through her work, she hopes to both advocate for and pioneer.

At the moment, she says, these changes haven't yet added up to a true transformation. On a global scale, we remain far from a genuine shift towards longer-term resilience. But as she points out, that can change quickly. After all, it has in the past. Just look at what got us here.

'The pursuit of economic growth became such a dominant focus in a relatively short time – only about seven decades,' she says. 'The shift toward longer-term resilience is certainly possible. Scientists and decision-makers just need to change their main goal to long-term resilience. The key question is, are our most powerful economic players wise enough to do so?'

As part of her research, Halme has led projects pioneering the kinds of changes that the fashion industry could adapt. For example, along with her Aalto colleague Linda Turunen, she recently developed a measurement that the fashion industry could use to classify how sustainable a product really is – measuring things like its durability, how easily it can be recycled, and whether its production uses hazardous chemicals – which could help consumers to decide whether to buy. Her colleagues curated a recent exhibition that showcased what we might be wearing in a sustainable future, such as a leather alternative made from discarded flower cuttings, or modular designs to get multiple uses from the same garment – turning a skirt into a shirt, for example.
 
Because all of this requires longer-term thinking, innovation and investment, industry is reticent to make these shifts, Halme says. One way to encourage industries to change more quickly is with regulation. In the European Union, for example, an updated set of directives now requires companies with more than 500 employees to report on a number of corporate responsibility factors, ranging from environmental impact to the treatment of employees. These rules won't just help inform consumers, investors and other stakeholders about a company's role in global challenges. They’ll also help assess investment risks – weighing whether a company is taking the actions necessary to be financially resilient in the long-term.

Promoting transparent supply chains and a more circular economy with digital product passports

Any prospective buyer interested in knowing more about the products they have set their eyes on will have to cope with limited information on print or online manuals or engage in time-consuming research. This may change soon, as the European Commission introduced a standardised digital product passport for the upcoming legislation. A project consortium has been formed with partners from industry and academia to set ground for the developments. The idea is for the proposed passports, supported by EU regulations, to make all product information available along the entire value chain and easily accessible e.g. by QR code.

Any prospective buyer interested in knowing more about the products they have set their eyes on will have to cope with limited information on print or online manuals or engage in time-consuming research. This may change soon, as the European Commission introduced a standardised digital product passport for the upcoming legislation. A project consortium has been formed with partners from industry and academia to set ground for the developments. The idea is for the proposed passports, supported by EU regulations, to make all product information available along the entire value chain and easily accessible e.g. by QR code.

ID cards and passports are usually the first things packed when one goes on a journey. They are internationally recognized and accepted documents with all the necessary information about the holder: Commonplace items for people that will soon become just as common for electronic devices, textiles, or batteries. But mobile phones, tablet computers, and their kin usually do not travel with a passport pouch, so their digital product passports with all their “personal details” will soon be accessible at every link in the value chain via a QR code or RFID chip.

Consumers looking to buy a new piece of clothing, a piece of electronics, or even furniture or toys should have more means to understand important information about their products, including their energy efficiency, the labor conditions during manufacturing, or their reparability, in order to make informed and sustainable purchasing choices.

Product passports also hold great potential for other actors, e.g. for repairs or recycling. Current electronic products, often highly miniaturized, make it hard to understand with materials, not least toxic substances are contained and how they could be separated from another. Use-specific certificates can regulate that this type of information is available to the people who need to know it.

No final decision has yet been made about the range of information that will be contained in the product passports. For the CIRPASS project, Eduard Wagner and his team at Fraunhofer ZM is currently surveying which types of information are already covered by current legal requirements and which additional information could be contained on a digital product passport. Their aim is to provide an information architecture that determines which types of information have added value for which actors in the value chain and at what cost this information could be provided. A reparability scale that shows how easily a product is to repair has been required in France since 2021 and might be a good inclusion in the digital, pan-European product passport. “Information about energy efficiency is already required, but this information still has to be prepared on a case-by-case basis, and there are no universal European disclosure requirements for other types of circularity related information. Meaningful standardization here is one of the top goals of the product passport. Imagine we could compare the durability of all t-shirts in the EU between each other,” says sustainability expert Eduard Wagner.

For the first product passports to be ready by 2026, many actors still need to be brought on board and a consensus be found for which information is most relevant. “Our project has identified 23 groups of stakeholders that we are including in our survey of requirements, in all three sectors”, Wagner explains. “We have suppliers of materials, manufacturers of electronics, and representatives of repair and recycling associations with us.” The results of these consultations will go to the European Commission to act as pointers for the political process en route to new legal requirements for the product passport. Small to medium-sized enterprises are given special attention and support in this, as providing the required information can mean a considerable effort on their part.

The impact of textile production and waste on the environment

  • With fast fashion, the quantity of clothes produced and thrown away has boomed.

Fast fashion is the constant provision of new styles at very low prices. To tackle the impact on the environment, the EU wants to reduce textile waste and increase the life cycle and recycling of textiles. This is part of the plan to achieve a circular economy by 2050.

Overconsumption of natural resources
It takes a lot of water to produce textile, plus land to grow cotton and other fibres. It is estimated that the global textile and clothing industry used 79 billion cubic metres of water in 2015, while the needs of the EU's whole economy amounted to 266 billion cubic metres in 2017.

To make a single cotton t-shirt, 2,700 litres of fresh water are required according to estimates, enough to meet one person’s drinking needs for 2.5 years.

Fast fashion is the constant provision of new styles at very low prices. To tackle the impact on the environment, the EU wants to reduce textile waste and increase the life cycle and recycling of textiles. This is part of the plan to achieve a circular economy by 2050.

To make a single cotton t-shirt, 2,700 litres of fresh water are required according to estimates, enough to meet one person’s drinking needs for 2.5 years.

The textile sector was the third largest source of water degradation and land use in 2020. In that year, it took on average nine cubic metres of water, 400 square metres of land and 391 kilogrammes (kg) of raw materials to provide clothes and shoes for each EU citizen.

Water pollution
Textile production is estimated to be responsible for about 20% of global clean water pollution from dyeing and finishing products.

Laundering synthetic clothes accounts for 35% of primary microplastics released into the environment. A single laundry load of polyester clothes can discharge 700,000 microplastic fibres that can end up in the food chain.

The majority of microplastics from textiles are released during the first few washes. Fast fashion is based on mass production, low prices and high sales volumes that promotes many first washes.

Washing synthetic products has caused more than 14 million tonnes of microplastics to accumulate on the bottom of the oceans. In addition to this global problem, the pollution generated by garment production has a devastating impact on the health of local people, animals and ecosystems where the factories are located.

Greenhouse gas emissions
The fashion industry is estimated to be responsible for 10% of global carbon emissions – more than international flights and maritime shipping combined.

According to the European Environment Agency, textile purchases in the EU in 2020 generated about 270 kg of CO2 emissions per person. That means textile products consumed in the EU generated greenhouse gas emissions of 121 million tonnes.

Textile waste in landfills and low recycling rates
The way people get rid of unwanted clothes has also changed, with items being thrown away rather than donated. Less than half of used clothes are collected for reuse or recycling, and only 1% of used clothes are recycled into new clothes, since technologies that would enable clothes to be recycled into virgin fibres are only now starting to emerge.

Between 2000 and 2015, clothing production doubled, while the average use of an item of clothing has decreased.

Europeans use nearly 26 kilos of textiles and discard about 11 kilos of them every year. Used clothes can be exported outside the EU, but are mostly (87%) incinerated or landfilled.

The rise of fast fashion has been crucial in the increase in consumption, driven partly by social media and the industry bringing fashion trends to more consumers at a faster pace than in the past.

The new strategies to tackle this issue include developing new business models for clothing rental, designing products in a way that would make re-use and recycling easier (circular fashion), convincing consumers to buy fewer clothes of better quality (slow fashion) and generally steering consumer behaviour towards more sustainable options.

Work in progress: the EU strategy for sustainable and circular textiles
As part of the circular economy action plan, the European Commission presented in March 2022 a new strategy to make textiles more durable, repairable, reusable and recyclable, tackle fast fashion and stimulate innovation within the sector.

The new strategy includes new ecodesign requirements for textiles, clearer information, a Digital Product Passport and calls companies to take responsibility and act to minimise their carbon and environmental footprints

On 1 June 2023, MEPs set out proposals for tougher EU measures to halt the excessive production and consumption of textiles. Parliament’s report calls for textiles to be produced respecting human, social and labour rights, as well as the environment and animal welfare.

Existing EU measures to tackle textile waste
Under the waste directive approved by the Parliament in 2018, EU countries are obliged to collect textiles separately by 2025. The new Commission strategy also includes measures to, tackle the presence of hazardous chemicals, calls producers have to take responsibility for their products along the value chain, including when they become wasteand help consumers to choose sustainable textiles.

The EU has an EU Ecolabel that producers respecting ecological criteria can apply to items, ensuring a limited use of harmful substances and reduced water and air pollution.

The EU has also introduced some measures to mitigate the impact of textile waste on the environment. Horizon 2020 funds Resyntex, a project using chemical recycling, which could provide a circular economy business model for the textile industry.

A more sustainable model of textile production also has the potential to boost the economy. "Europe finds itself in an unprecedented health and economic crisis, revealing the fragility of our global supply chains," said lead MEP Huitema. "Stimulating new innovative business models will in turn create new economic growth and the job opportunities Europe will need to recover."

Soundwaves to separate microplastics from wastewater

The technology developed by The Hong Kong Research Institute of Textiles and Apparel (HKRITA) with the support of H&M Foundation, can separate microplastics from wastewater using soundwaves. Acousweep is a plug-and-play application. The technology can be easily transported and connected to any wastewater facility. If the technology is implemented at an industrial scale, it will have a significant impact on the fashion industry’s sustainable footprint.

Acousweep is a plug-and-play application. The technology can be easily transported and connected to any wastewater facility. If the technology is implemented at an industrial scale, it will have a significant impact on the fashion industry’s sustainable footprint.
 
Microplastic pollution is a globally established problem and a threat to ecosystems, animals, and people. Microplastics come from a variety of sources, including from larger plastic debris that degrades into smaller and smaller pieces, or microbeads in exfoliating health and beauty products, or cleansers such as toothpaste. According to the European Environment Agency the major source of oceanic microplastic pollution, about 16%-35% globally, comes from synthetic textiles. Professor Christine Loh, Chief Development Strategist at the Institute for the Environment, The Hong Kong University of Science and Technology, agrees that this technology has great potential.

Microplastics typically refers to tiny plastic pieces or particles smaller than 5mm in diameter according to the definition of United Nations Environment Programme (UNEP) and the European Union (EU). The new technology can separate microplastic fibre longer than 20 μm, which is 250 times smaller than the typical size. Unlike existing filtration processes, the system enables continuous water treatment and easy collection of microplastic fibres by virtue of its acoustic manipulation technique.

Acousweep utilises sweeping acoustic waves in a specially shaped chamber to physically trap and separate microplastic fibres from wastewater effectively. The whole process is merely a physical collection and separation. No chemical, solvent or biological additives are needed. The separated microplastics drip into a collection tank for further treatment, such as recycling. Acousweep, with a developing lab-scale treatment system of the capacity of 100L of water per hour, can be upscaled in industrial plants. The system can be installed in a container with a processing capacity up to 5-10T per hour. The containerised system can be easily transported and connected to the existing sewage outlets of the wastewater treatment system.
 
Process of Microplastic Fibre Separation:

  1. At one end of the chamber is a transducer that generates a sweeping acoustic wave at ultrasound frequencies. At the other end, there is a reflector, inside which sweeping acoustic waves are reflected and forms standing waves.
  2. When standing waves are applied to the particles in a fluid, an acoustic radiation force traps the particles.
  3. The standing waves then transfer the trapped particles to the reflector side; after that, particles concentrate at the apex of the reflector.
  4. At the apex is a needle valve which is controlled by a sensory system that monitors the concentration of microplastic fibres there. When the concentration is sufficiently high, the sensory system opens the needle valve to let the microplastic fibres drip into a collection tank.
  5. A high temperature can be applied to the collection tank to remove the water, leaving the fibres to agglomerate and form a large mass that can be easily dealt with in future treatment.

Green tech has just taken a leap forward in Hong Kong. Acousweep will help the garment and other industries to stop a highly damaging form of pollution. HKRITA used a new technique to remove the microplastics by using soundwave-based system, preventing them from getting into the sea and being ingested by sea life that can even be ingested by humans along the food chain. Acousweep has the capacity to revolutionize industry, says Professor Christine Loh, Chief Development Strategist at the Institute for the Environment, The Hong Kong University of Science and Technology.

Sustainable natural-fiber reinforcement for textile-reinforced concrete components

Textile-reinforced concrete components with a sustainable natural-fiber reinforcement possess sufficient bond and tensile load-bearing behavior for the utilization in construction. This has been verified by researchers at the Fraunhofer WKI in collaboration with Biberach University of Applied Sciences and the industrial partner FABRINO. In the future, textile-reinforced components with natural-fiber reinforcement could therefore replace conventionally reinforced concrete components and improve the environmental balance in the construction industry.

Textile-reinforced concrete components with a sustainable natural-fiber reinforcement possess sufficient bond and tensile load-bearing behavior for the utilization in construction. This has been verified by researchers at the Fraunhofer WKI in collaboration with Biberach University of Applied Sciences and the industrial partner FABRINO. In the future, textile-reinforced components with natural-fiber reinforcement could therefore replace conventionally reinforced concrete components and improve the environmental balance in the construction industry.

Non-metallic reinforcements for concrete elements are currently often made from various synthetically produced fibers - for example from glass or carbon fibers. An ecological alternative to synthetic fibers is provided by flax or other natural fibers. These are widely available and are more sustainable, due, amongst other things, to their renewable raw-material basis, the advantages regarding recycling, and the lower energy requirements during production. This is where the researchers from the Fraunhofer WKI and Biberach University of Applied Sciences, in collaboration with an industrial partner, became active. Their goal was to demonstrate that reinforcements made from textile fibers are just as suitable for utilization in construction as synthetic fibers.

"At the Fraunhofer WKI, we have produced leno fabrics from flax-fiber yarn using a weaving machine. In order to enhance sustainability, we tested a treatment of the flax yarns for improving the tensile strength, durability and adhesion which is ecologically advantageous compared to petro-based treatments," explained Jana Winkelmann, Project Manager at the Fraunhofer WKI. In the coating process, a commonly used petro-based epoxy resin was successfully replaced by a partially bio-based impregnation. A large proportion (56%) of the molecular structure of the utilized epoxy resin consists of hydrocarbons of plant origin and can therefore improve the CO2 balance.

Textile reinforcements have a number of fundamental advantages. They exhibit, for example, significantly reduced corrodibility at the same or higher tensile strength than steel, with the result that the necessary nominal dimension of the concrete covering can be reduced. This often allows smaller cross-sections to be required for the same load-bearing capacity. Up to now, however, the load-bearing behavior of textile reinforcements made from natural fibers in concrete components has not been systematically investigated.

At Biberach University of Applied Sciences, researchers tested the bond and tensile load-bearing behavior as well as the uniaxial flexural load-bearing behavior of concrete components with textile reinforcement made from flax fibers. The scientists came to the conclusion that the natural-fiber-based textile-reinforced components with a bio-based impregnation are fundamentally suitable. The suitability was demonstrated by both a significant increase in the breaking load compared to non-reinforced and under-reinforced concrete components and in finely distributed crack patterns. The curves of the stress-strain diagrams could be divided into three ranges typical for reinforced expansion elements (State I - non-cracked, State IIa - initial cracking, and State IIb - final crack pattern). The delineation of the ranges becomes more pronounced as the degree of reinforcement increases.

As a whole, regionally or Europe-wide available, renewable natural fibers and a partially bio-based coating contribute towards an improvement of the CO2 footprint of the construction industry. As a result, a further opportunity is being opened up for the energy- and raw-material-intensive construction industry in terms of meeting increasingly stringent environmental and sustainability requirements. "Textile-reinforced concretes enable lighter and more slender structures and therefore offer architectural leeway. We would like to continue our research into the numerous application possibilities of natural-fiber-reinforced concretes," said Christina Haxter, a staff member at the Fraunhofer WKI.

The project, which ran from 9th December 2020 to 31st December 2022, was funded by the German Federal Environmental Foundation (DBU).

Prior to the conference, the conference advisory board had nominated six remarkable innovations. The winners were elected in an exciting head-to-head live-voting by the conference audience on the first day of the event.

The collaboration between Nanollose (AU) and Birla Cellulose (IN) with tree-free lyocell from bacterial cellulose called Nullarbor™ is the winning cellulose fibre innovation 2023, followed by Renewcell (SE) cellulose fibres made from 100 % textile waste, while Vybrana – the new generation banana fibre from Gencrest Bio Products (IN) won third place.
    
Winner: Nullarbor™ – Nanollose and Birla Cellulose (AU/IN)
In 2020, Nanollose and Birla Cellulose started a journey to develop and commercialize treefree lyocell from bacterial cellulose, called Nullarbor™. The name derives from the Latin “nulla arbor” which means “no trees”. Initial lab research at both ends led to the joint patent application “production of high-tenacity lyocell fibres made from bacterial cellulose”.
Nullarbor is significantly stronger than lyocell made from wood-based pulp; even adding small amounts of bacterial cellulose to wood pulp increases the fibre toughness. In 2022, the first pilot batch of 260 kg was produced with 20 % bacterial pulp share. Several high-quality fabrics and garments were produced with this fibre. The collaboration between Nanollose and Birla Cellulose now focuses on increasing the production scale and amount of bacterial pulp in the fibre.  

Second place: Circulose® – makes fashion circular – Renewcell (SE)
Circulose® made by Renewcell is a branded dissolving pulp made from 100 % textile waste, like worn-out clothes and production scraps. It provides a unique material for fashion that is 100 % recycled, recyclable, biodegradable, and of virgin-equivalent quality. It is used by fibre producers to make staple fibre or filaments like viscose, lyocell, modal, acetate or other types of man-made cellulosic fibres. In 2022, Renewcell, opened the world’s first textile-to-textile     
chemical recycling plant in Sundsvall, Sweden – Renewcell 1. The plant is expected to reach an annual capacity of 120,000 tonnes.

Third place: Vybrana – The new generation banana fibre – Gencrest Bio Products (IN)
Vybrana is a Gencrest’s Sustainable Cellulosic Fibre upcycled from agrowaste. Raw fibres are extracted from the banana stem at the end of the plant lifecycle. The biomass waste is then treated by the Gencrest patented Fiberzyme technology. Here, cocktail enzyme formulations remove the high lignin content and other impurities and help fibre fibrillation. The company's proprietary cottonisation process provides fine, spinnable cellulose staple fibres suitable for blending with other staple fibres and can be spun on any conventional spinning systems giving yarns sustainable apparel. Vybrana is produced without the use of heavy chemicals and minimized water consumption and in a waste-free process where balance biomass is converted to bio stimulants Agrosatva and bio-based fertilizers and organic manure.

Consortium for enzymatic textile recycling gains new supporters

"Shared vision of a true circular economy for the textile industry"

US fashion group PVH has joined the fibre-to-fibre consortium founded by Carbios, On, Patagonia, PUMA and Salomon. The aim is to support the further development of Carbios' biorecycling process on an industrial scale, setting new global standards for textile recycling technologies. PVH owns brands such as Calvin Klein and Tommy Hilfiger. In the agreement signed by PVH Corp, the company commits to accelerating the textile industry's transition to a circular economy through its participation in the consortium.

Carbios is working with On, Patagonia, PUMA, PVH Corp. and Salomon to test and improve its bio-recycling technology on their products. The aim is to demonstrate that this process closes the fibre-to-fibre loop on an industrial scale, in line with sustainability commitments.

Carbios is working with On, Patagonia, PUMA, PVH Corp. and Salomon to test and improve its bio-recycling technology on their products. The aim is to demonstrate that this process closes the fibre-to-fibre loop on an industrial scale, in line with sustainability commitments.

The two-year cooperation project will not only enable the biological recycling of polyester articles on an industrial scale, but also develop thorough sorting and disassembly technologies for complex textile waste. Existing members voted unanimously for PVH Corp. to join the consortium, saying the common goal is to support the development of viable solutions that address the fashion industry's contribution to climate change..

Carbios has developed a technology using highly selective enzymes that can recycle mixed feedstocks, reducing the laborious sorting required by current thermomechanical recycling processes. For textiles made from blended fibres, the patented enzyme acts only on the PET polyester contained within. This innovative process produces recycled PET (r-PET) that is equivalent in quality to virgin PET and can be used to produce new textile fibres.

Textile waste treatment and recycling
Globally, only 13% of textile waste is currently recycled, mainly for low-value applications such as upholstery, insulation or rags. The remaining 87% is destined for landfill or incineration. To work on improving textile recycling technologies, consortium members will supply feedstock in the form of clothing, underwear, footwear and sportswear. In 2023, a new PET textile waste facility will be commissioned at the Carbios demonstration plant, notably as part of the LIFE Cycle of PET project co-funded by the European Union.  This is in anticipation of future regulations, such as the separate collection of textile waste, which will be mandatory in Europe from 1 January 2025.

From fibre to fibre: circularity of textiles
Today, the textile industry relies largely on non-renewable resources to produce fibres and fabrics, partly turning to recycled PET bottles for recycled polyester fibres. However, this resource will become scarce as PET bottles are used exclusively for the production of new bottles in the food and beverage industry. In a circular economy, the materials used to produce textiles are obtained from recycled or renewable raw materials produced by regenerative processes. In addition to supplying raw materials for the demonstration plant, the consortium members also aim to produce new products from r-PET fibres using the company's biorecycling process.

"Partnering with Carbios and its consortium members demonstrates our continued commitment to incorporating more circular materials into our collections," said Esther Verburg, EVP, Sustainable Business and Innovation, Tommy Hilfiger Global and PVH Europe. "We are excited to support the development of Carbios' enzymatic recycling technology and to leverage new solutions that can help us drive fashion sustainably."

The new butterfly effect: A ‘game changer’ for clothing recycling?

Photonic fibers borrow from butterfly wings to enable invisible, indelible sorting labels

Less than 15% of the 92 million tons of clothing and other textiles discarded annually are recycled—in part because they are so difficult to sort. Woven-in labels made with inexpensive photonic fibers, developed by a University of Michigan-led team, could change that.
 
“It’s like a barcode that’s woven directly into the fabric of a garment,” said Max Shtein, U-M professor of materials science and engineering and corresponding author of the study in Advanced Materials Technologies. “We can customize the photonic properties of the fibers to make them visible to the naked eye, readable only under near-infrared light or any combination.”

Less than 15% of the 92 million tons of clothing and other textiles discarded annually are recycled—in part because they are so difficult to sort. Woven-in labels made with inexpensive photonic fibers, developed by a University of Michigan-led team, could change that.
 
“It’s like a barcode that’s woven directly into the fabric of a garment,” said Max Shtein, U-M professor of materials science and engineering and corresponding author of the study in Advanced Materials Technologies. “We can customize the photonic properties of the fibers to make them visible to the naked eye, readable only under near-infrared light or any combination.”

Ordinary tags often don’t make it to the end of a garment’s life—they may be cut away or washed until illegible, and tagless information can wear off. Recycling could be more effective if a tag was woven into the fabric, invisible until it needs to be read. This is what the new fiber could do.
 
Recyclers already use near-infrared sorting systems that identify different materials according to their naturally occurring optical signatures—the PET plastic in a water bottle, for example, looks different under near-infrared light than the HDPE plastic in a milk jug. Different fabrics also have different optical signatures, but Brian Iezzi, a postdoctoral researcher in Shtein’s lab and lead author of the study, explains that those signatures are of limited use to recyclers because of the prevalence of blended fabrics.

“For a truly circular recycling system to work, it’s important to know the precise composition of a fabric—a cotton recycler doesn’t want to pay for a garment that’s made of 70% polyester,” Iezzi said. “Natural optical signatures can’t provide that level of precision, but our photonic fibers can.”

The team developed the technology by combining Iezzi and Shtein’s photonic expertise—usually applied to products like displays, solar cells and optical filters—with the advanced textile capabilities at MIT’s Lincoln Lab. The lab worked to incorporate the photonic properties into a process that would be compatible with large-scale production.
 
They accomplished the task by starting with a preform—a plastic feedstock that comprises dozens of alternating layers. In this case, they used acrylic and polycarbonate. While each individual layer is clear, the combination of two materials bends and refracts light to create optical effects that can look like color. It’s the same basic phenomenon that gives butterfly wings their shimmer.

The preform is heated and then mechanically pulled—a bit like taffy—into a hair-thin strand of fiber. While the manufacturing process method differs from the extrusion technique used to make conventional synthetic fibers like polyester, it can produce the same miles-long strands of fiber. Those strands can then be processed with the same equipment already used by textile makers.

By adjusting the mix of materials and the speed at which the preform is pulled, the researchers tuned the fiber to create the desired optical properties and ensure recyclability. While the photonic fiber is more expensive than traditional textiles, the researchers estimate that it will only result in a small increase in the cost of finished goods.

“The photonic fibers only need to make up a small percentage—as little as 1% of a finished garment,” Iezzi said. “That might increase the cost of the finished product by around 25 cents—similar to the cost of those use-and-care tags we’re all familiar with.”

Shtein says that in addition to making recycling easier, the photonic labeling could be used to tell consumers where and how goods are made, and even to verify the authenticity of brand-name products. It could be a way to add important value for customers.

“As electronic devices like cell phones become more sophisticated, they could potentially have the ability to read this kind of photonic labeling,” Shtein said. “So I could imagine a future where woven-in labels are a useful feature for consumers as well as recyclers.”

The team has applied for patent protection and is evaluating ways to move forward with the commercialization of the technology.

... and they actually can be recycled: Wind Turbine Blades

The Danish company Continuum Group ApS with its subsidiary companies in Denmark (Continuum Aps) and the UK (Continuum Composite Transformation (UK) Limited) wants to give end-of-life wind blades and composites a new purpose, preventing them going to waste. The goal is to reduce the amounts of CO2 emitted to the atmosphere by the current waste streams, delivering a value to Europe’s Net Zero efforts.

Continuum states that it ensures all wind turbine blades are 100% recyclable and plans to build industrial scale recycling factories across Europe.

Net zero is the phrase on everyone’s lips, and as 2030 rapidly approaches we constantly hear updates about wind energy generating renewable energy that powers millions of European homes – but what happens when those turbine blades reach the end of their lifespan?

The goal is to reduce the amounts of CO2 emitted to the atmosphere by the current waste streams, delivering a value to Europe’s Net Zero efforts.

Continuum states that it ensures all wind turbine blades are 100% recyclable and plans to build industrial scale recycling factories across Europe.

Net zero is the phrase on everyone’s lips, and as 2030 rapidly approaches we constantly hear updates about wind energy generating renewable energy that powers millions of European homes – but what happens when those turbine blades reach the end of their lifespan?

Currently the general answer is to put them into landfill or co-process them into cement, but neither is planet friendly. Many countries in Europe look to ban landfill from 2025, so this option is likely to be eliminated in the near future.

Continuum provides an alternative: When the end of their first life arrives, Continuum recycles them into new, high performing composite panels for the construction, and related industries. The vision of the Danes: Abandon the current landfilling, and drastically reduce CO2 emitted during currently applied incineration & co-processing in cement factories by 100 million tons by 2050, via their mechanical composite recycling technology and their industrial scale factories.  

The technology is proven, patented, and ready to go, says Reinhard Kessing, co-founder and CTO of Continuum Group ApS, who has spent more than 20 years of research and development in this field, and advanced the reclamation of raw materials from wind blades and other composite products and transformation of these materials into new, high performing panel products.

By working with partners, Continuum’s cost-effective solution covers end-to-end logistics and processes. This spans from the collection of the end-of-life blades through to the reclamation of the pure clean raw materials and then the remanufacturing of all those materials into high value, highly performing, infinitely recyclable composite panels for the construction industry or the manufacture of many day-to-day products such as facades, industrial doors, and kitchen countertops. The panels are 92% recycled blade material and are said to outperform competing products.

Nicolas Derrien: Chief Executive Officer of Continuum Group ApS said: “We need solutions for the disposal of wind turbine blades in an environmentally friendly manner, we need it now, and we need it fast, and this is where Continuum comes in! As a society we are rightly focussed on renewable energy production, however the subject of what to do with wind turbine blades in the aftermath of that production has not been effectively addressed. We’re changing that, offering a recycling solution for the blades and a construction product that will outperform most other existing construction materials and be infinitely recyclable, and with the lowest carbon footprint in its class.”

Martin Dronfield, Chief Commercial Officer of Continuum Group ApS and Managing Director of Continuum Composite Transformation (UK) Ltd, adds: “We need wind energy operators & developers across Europe to take a step back and work with us to solve the bigger picture challenge. Continuum is offering them a service which won’t just give their business complete and sustainable circularity to their operations but help protect the planet in the process.“

Each Continuum factory in Europe will have the capacity to recycle a minimum of 36,000 tons of end-of-life turbine blades per year and feed the high value infinitely recyclable product back into the circular economy by 2024/25.

Due to an investment by Climentum Capital and a grant from the UK’s ‘Offshore Wind Growth Partnership’, Continuum are planning for the first of six factories in Esbjerg to be operational by the end of 2024 and for a second factory in the United Kingdom to follow on just behind it. After that they are looking to build another four in France, Germany, Spain, and Turkey by 2030.

As part of their own pledge to promote green behaviour, Continuum have designed their factories to be powered by only 100% green energy and to be zero carbon emitting environments; meaning no emissions to air, no waste fluids to ground, and no carbon fuel combustion.

Circular Economy: It could all be so simple... or not

Interview with Henning Wehland & Robert Kapferer, Circularity Germany

Interview with Henning Wehland & Robert Kapferer, Circularity Germany

I'm a very curious guy by nature. That's why I offered to help out at a well-known hot dog station in Münster (Germany) this year, to draw attention to the shortage of staff in the gastronomy. I wrote an article about it on LinkedIn, which was in turn reacted to by Ines Chucholowius.
From her profile, I could see that she is a consultant for strategic marketing and communication in the textile industry. Not entirely serious, she offered me a job in her office. Like pushing a button, the pictures in my mind set in: Textile industry, exciting! Merchandising, contacts in the industry, collaborations, and I agreed to a short chat, at the end of which we spoke on the phone and arranged to meet.
 
She told me about her website TEXTINATION.de. And we were already involved in an exciting, heated exchange about perception and truth in the textile industry. Without further ado, we left it at that and I went home with a chunk of new information about an exciting field. Our dialogue on social media continued and eventually Ines offered me the chance to feed my die-hard curiosity with the support of TEXTINATION.de. I could write a blog on the site, about people, products, service providers, producers, startups or trends that interest me, to add to my half-knowledge about the textile industry.

Textile waste into the front ... new T-shirt out the back
During this exchange and a long brainstorming session, certain terms kept tickling my attention:
Circular economy, recycling, recyclable material loops. Circular Economy, Recycling, Recyclables. Even though there are many different definitions and some even distinguishing between different aspects: the former thought from waste that flows back into production as a secondary raw material, a more modern approach avoiding waste already in production - the general consensus is really only that circular economy is a cycle in which waste is used as a source for something new.

Sounds like useful additions for all areas of the manufacturing real economy to me. Ines introduced me to Robert Kapferer: He runs a startup called Circularity Germany in Hamburg. His company, founded in 2021 and consisting of Robert and another partner, is an offshoot of the Dutch-based company Circularity B.V. Its founder Han Hamers, with a degree in child psychology and a professional background in the textile dyeing industry, had the idea five years ago for a production facility that spins new yarn exclusively from textile production waste and old textiles turning it into T-shirts, polo shirts and sweatshirts.
Whether this works, and if so, how, is what I wanted to find out, and Ines and I arranged to meet Robert for a 90-minute online conference.

Robert, originally an industrial engineer, comes from a less sustainable industry. He worked for 11 years as managing director for AVECO Material und Service GmbH, where he was responsible for the workwear of more than 50,000 employees.

At the beginning of our conversation, he emphasizes that a moment in January 2021 changed his life and from then on, he wanted to dedicate himself to the topic of circular economy with all his might. That was when he met Han Hamers, who inspired him to found Circularity Germany. His enthusiasm and passion for the subject sound credible, and he begins to describe the differences between chemical and mechanical recycling methods. In summary, the mechanical process of shredding and the subsequent spinning shortens the fibers and thus restricts their properties for further processing. The advantage lies primarily in the comparatively uncomplicated, fast and more cost-efficient process. In the chemical variant, chemical waste remains, but the processed materials are broken down again into their basic building blocks in such a way that they have almost all the same properties as a so-called virgin raw material. Circularity Germany stands for the mechanical process.

And then comes the sentence that gets all our attention: "We've advanced a spinning technology so much that it relies exclusively on waste-based raw materials."
This sentence almost doesn't stand out because Robert still talks - quite excitingly - about the fact that they are planning a production and manufacturing facility where everything from knitting yarn to relatively fine thread can be spun and then further processed into fabric. And here Ines and I ask intensively: Essential requirements for industrial production still seem to be unresolved, and necessary processes are still in the planning stage. For example, the question of whether to work with pre-consumer or post-consumer waste. Pre-consumer waste is cutting waste from the production of clothes, which corresponds to about 10% of the processed material. Post-consumer waste we know as used textiles.

As long as production still takes place in India, Circularity currently uses mainly pre-consumer waste. These come exclusively from sewing factories in the Tirupur region in the south of India. When using used textiles, which exist in large quantities in Germany (according to a study, 28-40% of all garments produced are thrown away unworn), Circularity produces blended yarns of cotton and polyester. The company does not offer pure cotton yarns.

Textiles are treated with chemicals to varying degrees - workwear in particular cannot do without them. The fact that Han Hemers is also collecting used textile stocks from the Dutch army in order to reintroduce them renewed into the consumer cycle is therefore not reassuring. Military clothing has to be finished with all kinds of additives.

Therefor I ask how he can dispel doubts in a consumer’s mind like mine, with a healthy half-knowledge of mask deals and greenwashing, that a well-intentioned vision will be followed by a dark awakening. This concern cannot yet be resolved after the conversation.

We limit ourselves to what is planned: Robert has the dream of reversing the globalized process of textile production. He wants to end the decoupling of cotton growing regions and far-flung production such as Asia with subsequent shipping of ready-made goods to Europe. In the future, existing used textiles and/or cutting wastes are to be collected on site, recycled and processed locally into new textiles.

I believe him in having this dream. However, some of my questions about sustainability remain unanswered - which is why I have my doubts about whether the idea is currently capable of performing and competing.
What are the reasons for this? For one thing, I think it's always difficult to do necessary pioneering work. Especially when listening to smart comments at the regulars' table that large companies are already working intensively on the principle of circular economy. But sometimes, apart from the term "circular economy" and a vague commitment to it, not much remains.

Circularity Germany is committed to developing a technology based exclusively on waste. The interview points out that this also includes making production more environmentally friendly and eliminating transport routes, which further reduces the burden on the environment. When all the requirements for realizing this dream have been met and a product that is competitive in terms of both quality and price can be launched on the market, it is up to the consumer to decide. Here one would have the credible argument of sustainability and a socially and environmentally fair process. Circularity would then not have to worry about PR.

It needs to be given time and, above all, attention. But perhaps the industry should get involved right here and now, and invest in startups like this and make sure that problems are cleared out of the way. Because one thing has become clear to us in this conversation:

It could all be so simple. Circular economy is achievable, but the road there is still costly and rocky. That's why we wish Robert and his team every success and, above all, perseverance. Thank you for the interview.

Marta Giralt Dunjó of futures research agency FranklinTill (Great Britain) presented the design prognoses for 23/24. At the coming Heimtextil in Frankfurt am Main from 10 to 13 January 2023, the presentations of new products will generate stimulating impulses in the Trend Space.

The Heimtextil Trend Council – consisting of FranklinTill Studio (London), Stijlinstituut Amsterdam and Denmark’s SPOTT Trends & Business agency – offers insights into the future of the national and international market. The focus is more than ever before on sustainability and the circular economy, the main factors in setting the trends for the season 23/24.

Textiles Matter: bear responsibility
Textiles are an integral part of modern life. The material applications and the manufacturing processes are no less multifarious than user expectations. And this represents a great challenge for the international textile industry, which obtains its raw materials from a broad spectrum of sources and uses numerous processes to make a huge variety of products. This offers a great potential for the sustainable development of the textile industry in the future. The Heimtextil Trends show ways in which this potential can be utilized and sustainable developments promoted. Under the motto ‘Textiles Matter’, visitors can explore concepts for increased circularity, which will generate new impulses for the sustainable market of the future.

"Considering the state of environmental emergency we are currently living through, the textile industry has a responsibility to examine its processes, and change for the better. That is why for this edition of the Heimtextil Trends we are taking a material’s first approach, and focusing on the sourcing, design, and sustainability of materials. Textiles Matter showcases the potential of circularity and celebrates design initiatives that are beautiful, relevant and importantly sustainable”, explains Marta Giralt Dunjó of FranklinTill.

Change via circularity
The Trend Space at the coming Heimtextil 2023 will revolve around ideas and solutions for circularity in the textile sector. How can textiles be produced in a sustainable way? What recycling options are there? What does the optimum recycling of textile products look like? Within the framework of the circular economy, materials are continuously reused. On the one hand, this reduces the need for new raw materials and, on the other hand, cuts the amount of waste generated. In the technical cycle, inorganic materials, such as nylon, polyester, plastic and metal, can be recycled with no loss of quality. In the biological cycle, organic materials, such as linen and bast fibres, are returned to nature at the end of their useful life. This is the basis of the four trend themes: ‘Make and Remake’, ‘Continuous’, ‘From Earth’ and ‘Nature Engineered’.

Make and Remake
Pre-used materials, deadstock and remnant textiles are given a new lease of life with the focus shifting to the aesthetics of repair and taking the form of a specific design element of the recycled product. Bright and joyful colours and techniques, such as overprinting, overdyeing, bricolage, collage and patchwork, result in new and creative products. Layered colour patterns and graphics lead to bold and maximalist, yet conscious, designs.

Continuous
The Continuous trend theme describes closed-loop systems in which materials are recycled into new, waste-free products again and again. Putative waste materials are separated out and reprocessed as new fibres, composites and textiles. Thus, synthetic and cellulose yarns can be produced zero-waste. Thanks to technically advanced reclamation processes, the materials retain their original quality and aesthetic. Practicality, essentialism and longevity determine the design of Continuous products.

From Earth
This theme focuses on the natural world and harmony with the nature of organic materials. Natural colours communicate warmth and softness. Imperfect textures, signs of wear and irregularities create ecological and earth-born aesthetics. Earthen and botanic shades, natural variation and tactile richness dominate the From Earth segment. Unrefined and raw surfaces, unbleached textiles and natural dyes celebrate materials in their original states.

Nature Engineered
Nature Engineered uses mechanical means to elevate and perfect organic materials, such as bast fibres, hemp, linen and nettles. Cutting-edge techniques process natural textiles into sophisticated and smart products. Combined with shades of beige and brown, clean lines and shapes are the distinguishing features of this theme.

Green chemistry transforms facemasks into Ethernet cables

Swansea University academics have pioneered a process which converts the carbon found in discarded facemasks to create high-quality single-walled carbon nanotubes (CNT) which were then used to make Ethernet cable with broadband quality.
 
The study, which has been published in Carbon Letters, outlines how this new green chemistry could be used to upcycle materials which would otherwise be thrown away and transform them into high value materials with real-world applications. The CNTs produced by this technique have the potential not only to be used in Ethernet cables, but also in the production of lightweight batteries used in electric cars and drones.

The CNTs produced by this technique have the potential not only to be used in Ethernet cables, but also in the production of lightweight batteries used in electric cars and drones.

Professor Alvin Orbaek White, of Swansea University’s Energy Safety Research Institute (ESRI):
“Single-use facemasks are a real travesty for the recycling system as they create vast amounts of plastic waste - much of it ending up in our oceans. During the study, we established that the carbon inside the facemask can be used as a pretty good feedstock to make high-quality materials like CNTs.

“CNTs are highly sought-after because they have preferential physical properties and tend to be much more costly on an industrial scale. So, through this study, we demonstrated that we could make very high value materials by processing the CNTs from what are, essentially, worthless waste facemasks.”

The team also studied the energy costs involved in using this process and concluded that the technique was green not only in levels of resource consumption but also in the product value generation as opposed to waste creation. Also, the Ethernet cable produced using the CNTs was good quality and adhered to Category 5 transmission speeds while easily exceeding the benchmarks set for broadband internet in most countries, including the UK.

Professor Orbaek White said:
“Using CNT films in batteries instead of metal films has a lower impact on the environment as the use of carbon offsets the need for mining and extraction activities. This is a crucial piece of work as it contributes to not only a circular economy but is also scalable and is viable for industrial processing and has green chemistry at its core.”

  • Jury presents two awards for outstanding fabric Innovation

The next PERFORMANCE DAYS will take place from November 3-4, 2022 at the MOC Ordercenter in Munich. Visitors also have the opportunity to follow the events online. Thanks to the new platform The Loop, all important information is available all year round, including current trends, new material innovations and extended tools for ease of use. The focus of the curated PERFORMANCE FORUM continues in winter honoring the winners of both awards. This year, in addition to a PERFORMANCE AWARD, the jury also presented an ECO PERFORMANCE AWARD.

Sustainable & innovative: the award winners of the Winter 2024/25 season
As part of the winter edition of the sourcing fairs, the fabric highlights plus accessory trends in the individ-ual categories for the winter season 2024/25 will be on display at the PERFORMANCE FORUM.
 
Particularly striking this year was the high levels of innovation and quality of many submitted fabrics on the one hand, but on the other hand – also as a result of this year’s Focus Topic – the sustainable component. “We wish to enable our visitors to make the best decision in terms of material selection, also in terms of CO2 neutrality and ultimately also in terms of textile recyclability,” states Marco Weichert, CEO of PERFORMANCE DAYS.  

Nevertheless, the road to CO2 neutrality remains a long one, yet the approaches adopted with the Focus Topic ongoing until the coming spring can be seen in a positive light. In general, manufacturers are increasingly relying on the use of natural fibers when possible, such as Tencel™ or other plant fibers – most of them also prove a low CO2 balance during production. The issue of recycling comes with many new facets and wide spanning trends. The portfolio ranges from the recycling of marine waste, such as old buoys, plastic waste or fishing nets, to the recycling of waste from the automotive and computer industries, such as old car tires or computer chips. Natural dyeing methods are also gaining in importance, as is the return of fabrics to the textile cycle.

In the Marketplace, visitors have the opportunity to view over 19,000 products from exhibitors, including the fabric highlights of the individual categories at the PERFORMANCE FORUM. In order for visitors to experience the fabrics in terms of haptics, design and structure in as realistic a form as possible, the PERFORMANCE FORUM has been equipped with innovative 3D technology, including innovative tools such as 3D images, video animations and U3MA data for download.

The jury has also presented two awards for outstanding fabrics for the Winter Season 2024/25 – with the PERFORMANCE AWARD going to Long Advance Int. Co Ltd., and the ECO PERFORMANCE AWARD to PontetortoSpa.

The ECO PERFORMANCE AWARD goes to “9203/M/RC” from PontetortoSpa: High Performance despite maximum sustainability
The fabric is a blend of 23 % hemp, 69 % recycled polyester and 9 % recycled elastane. Moreover, the material boasts a low CO2 footprint during production and focuses on low release levels of microplastics into the environment. “9203/M/RC” belongs to Pontetorto's Techno Stretch organic series, which boast an excellent 4-way stretch with great elasticity. In addition, it guarantees fast drying and optimal breathability. The polyester yarn is manufactured by the mechanical recycling of plastic bottles. Hemp, the most water–repellent among natural fibers, allows for quick drying and provides optimal comfort. Hemp is considered an extremely sustainable natural fiber due to its origin from an anti–bacterial plant that requires neither pesticides nor chemical fertilizers during its growth and consumes extremely little water.

PERFORMANCE AWARD for “LPD-22015-Y4E” from Long Advanced Int. Co. Ltd.: Perfect recycling for top performance
The monocomponent 2layer fabric is a mixture of 45 % polyester mechanical stretch and 55 % recycled polyester from recycled textiles, laminated with a PET Membrane, with a weight of 147 grams.
The special feature of the “LPD 22015-Y4E” is the recycling of fabric and cutting waste. Waste is thus returned to the textile cycle and used to spin new yarn. In the future, manufacturers will have to ensure that all fabric can be recycled. Accordingly, the production of waste is then reduced by 30 % compared to conventional processes. Furthermore, the jury praised the feel and the extraordinary look of the material.

The entire PERFORMANCE FORUM including both awards can be experienced live at the fair on October 26-27, 2022 in Portland, Oregon, and in Munich at the PERFORMANCE DAYS fair on November 03-04, 2022. As of now, all innovative materials can also be found online in the Marketplace of the PERFORMANCE DAYS Loop, with the option to order free samples directly from the exhibitor.

The future of fashion: Revolution between fast and slow fashion

The fashion industry is massively influenced by the change in social values. Which trends can be observed and in which direction is the fashion future developing - an excerpt from the Retail Report 20231 by Theresa Schleicher.

The fashion industry is massively influenced by the change in social values. Which trends can be observed and in which direction is the fashion future developing - an excerpt from the Retail Report 20231 by Theresa Schleicher.

The fashion industry has been slowed down by the global health pandemic and further affected by the measures taken in the wake of the Ukraine war: Fragile supply chains, increased transportation and energy costs, and rising prices are having an impact on the globalized fashion industry. Those who were moving the fastest are being hit the hardest. Fast fashion based on the principle of "faster and faster, cheaper and cheaper, more and more" - which has been in the fast lane for years - is now experiencing an unprecedented crash. Even without these momentous events, the fashion system would have reached its limits. What could have developed evolutionarily is now being revolutionized. Now and in the future, it will be particularly difficult for brands and retail companies that do not have a sharp profile or that have lost many customers in the attempt to offer mass-produced goods at prices that are still lower than those of their competitors.

New value paradigm in society - also for fashion
While fashion retailers and fashion brands are focusing on expanding online and have been putting their foot on the gas pedal since the corona pandemic at the latest, a parallel change in values is taking place in society. Many behaviors that have been practiced, tested and lived for months will continue to shape our consumer behavior and lifestyles in the future. The uncertainty in society as well as a shrinking economy and rising consumer prices as a result of the Ukraine war will further contribute to this shift in values.

The old paradigm was "primarily shaped by pragmatic factors such as price, quantity, safety and convenience, so consumer behavior was predominantly based on relatively simple cost-benefit calculations." The new value paradigm, on the other hand, is more strongly influenced by "soft factors". For example, the quality of a product is defined more holistically. In addition to price, "ecological, [...] ethical and social aspects are also taken into account. It is about positive or negative experiences that one has had with producers and about the visions that they pursue with their companies". This new value paradigm is forcing the large chain stores in particular to rethink. They have to develop their business models further in the direction of sustainability, transparency and responsibility - and show attitude. The influence of the neo-ecology megatrend combined with the push towards the sense economy is reshuffling the cards in the fashion industry.

The most important driver for the change in consumer behavior is climate protection, which is also becoming personally more important to more and more people because they are feeling the effects of climate change themselves in their everyday lives. The transition to a sustainable, bio-based and circular economy is accompanied by fundamental changes in the technical, economic and social environment.

Circular fashion as an opportunity for fast fashion
The development of the fashion industry - especially the fast fashion industry - towards a more circular economy is not a short-term trend, but one of the most long-term and at the same time forward-looking trends in retailing of all.

Even before the pandemic, a growing proportion of consumers placed value on sustainably produced clothing instead of constantly shopping the latest trends. A reset is needed, but the fashion industry faces a difficult question: How can it respond to the demand for new trends without neglecting its responsibility for the environment?

The solution for reducing emissions and conserving raw materials and resources seems obvious: produce less. On average, 2,700 liters of water are needed to produce a T-shirt - that much drinking water would last a person for two and a half years. In Europe, each person buys an average of 26 kilograms of textiles per year - and disposes eleven kilograms. Of this, almost 90 percent is incinerated or ends up in landfills. Overproduction, precarious working conditions during production and the use of non-sustainable materials are the major problems of the fast fashion industry. It is time to slow down fast fashion.

Fashion recycling by Design & Recycling as a Service
A first step towards keeping fashion and textiles in the cycle for longer is to recycle materials properly. In the future, recycling must be considered as early as the design stage - not only for sustainably produced fashion, but also for fast fashion. The H&M Group, for example, developed the Circulator for this purpose: The digital evaluation tool guides the designer through materials, components and design strategies that are best suited for the product depending on its purpose, and evaluates them in terms of their environmental impact, durability and recyclability.

However, more and more young companies are specializing in offering recycling for textiles as a service. They work directly with fashion retailers or fashion brands to enable the best possible recycling, re-circulation or even upcycling. Until now, it has not been worthwhile for large textile companies to invest in their own recycling systems. But Recycling as a Service is a market of the future, led by innovative start-ups such as Resortecs that are tackling previous hurdles in our recycling system. In the future, more and more new service providers will pop up around returns and recycling and help fashion retailers to align their material cycles more sustainably.

Secondhand conquers the fast fashion market
Another way to extend the life of clothing is to pass it on to new users. We are witnessing the triumph of vintage, retro and more - chic secondhand stores and chains like Resales and Humana are popping up everywhere. The renaming of secondhand to pre-owned or pre-loved also illustrates the increased appreciation of worn clothing. The trend toward secondhand also pays off economically for companies: The number of platforms whose business model revolves around the resale of clothing is increasing, and secondhand fashion is arriving in the middle of society. The luxury segment and especially vintage fashion are stable in price because the availability of these unique pieces is limited. Fast fashion, on the other hand, is available in sufficient quantities and is particularly interesting for price-sensitive customers, as secondhand is considered one of the most sustainable forms of consumption - meaning that fashion can be shopped with a clear conscience - and is usually even offered at a lower price than new goods. The second-hand market will continue to professionalize and become more socially acceptable. As a result, the fast fashion industry will also be forced to produce higher quality clothing in order to become or remain part of the circular system.

Slow fashion gains momentum thanks to technology
The development and orientation of fast fashion towards circular processes is also changing sustainable fashion. In the future, fast fashion and slow fashion can learn from each other to fully exploit their potential: fast fashion will become more sustainable, while slow fashion will focus on faster availability and delivery and make the customer experience as pleasant as possible. Fast and slow fashion are no longer compelling opposites - because the sustainable fashion movement can also benefit from technological innovations that are being established above all by the fashion platforms, and lift slow fashion to a new level.

At the same time, Sustainable Luxury is a new form of luxury consumption - especially in the field of designer fashion, sustainability is becoming the all-important criterion. Sustainability as a means of distinction for true luxury and sustainability as a basic prerequisite for a functioning fashion industry are increasingly converging. This is where the transition between a slowdown of fast fashion and an acceleration of slow fashion takes place.

Trend Sustainable Luxury
Luxury is defined less and less by the object and its possession and is increasingly becoming an expression of one's own lifestyle and values. Consumers' understanding of premium and luxury has changed - not least driven by the neo-ecology megatrend. In the future, it will no longer be just about owning something as expensive and ostentatious as possible. What began as a rebellion against careless consumption of luxury brands that promise high-end products but accept unfair and environmentally damaging manufacturing conditions in the process has increasingly become accepted as a value attitude. Luxury products have no less a claim than to improve the world.

Sustainable and ethical products and services made from innovative materials that have the power to solve problems and make the world a better place. At the same time, this highly ethically and morally charged form of sustainability is turning into a means of distinction: For the materials are so new, the manufacturing processes still so experimental, that the products are unique and often only available in very small quantities or on order. And this exclusive sustainability naturally comes at a price. After all, a company that pursues a mission is not concerned with simply cutting costs - certainly not at the expense of others or the environment. Instead of leather and fur, luxury fashion is now made from oranges, pineapples, hemp, cacti: there are more and more new, innovative and sustainable materials from which unique garments and accessories can be made.

Predictive, Pre-Order & Made-to-Order
Artificial intelligence and Big Data analysis can help predict fashion demand. Fast fashion leaders like Shein are characterized by agile production which is supported by AI algorithms for trend prediction fed with data from TikTok and other social media services. This could sustainably reduce overproduction and unsaleable goods in the future. As critical as Shein's practices are, the automation of processes also offers immense opportunities for a more sustainable fashion industry, as production only starts when goods are in demand.

AI support in the design process can be used to produce more sustainable fashion - and make it available more quickly. In a future of an avatar economy and in the world of virtual influencers, it may even be possible to dispense with part of the production process: Fashion will remain virtual - and thus more resource-efficient. Digital fashion will become increasingly important as the metaverse is built.

5 Key Takeaways on the Future of Fashion

  1. The current crisis in the fashion industry is an opportunity to move more in the direction of circular fashion. Above all, the new value paradigm in society, understanding quality more holistically and consuming more mindfully, is providing a push towards fairer, more ecological and more social fashion. Fast fashion and sustainability are not mutually exclusive.
  2. There are already first approaches to keep fast fashion in the cycle longer or to return it to the cycle. One important development is to consider recycling or reuse as early as the design and manufacturing process - known as recycling by design. In addition, there is a growing number of start-ups specializing in the optimized recycling of textiles and cooperating with major fashion players.
  3. Above all, the booming online trade in used fashion, often communicated as the pre-loved or pre-owned category, is making secondhand respectable for the mainstream. Such fashion, with a story and an aura of uniqueness, is also a cost-effective but more sustainable alternative to fast fashion.
  4. But slow fashion is also changing, especially due to the dominance of new technologies. Slow fashion can also benefit from processes that are currently manifesting themselves in the online fashion market, such as fast delivery or pre-order services. Slow fashion thus becomes more convenient, better and faster available. It will be easier for sustainably oriented fashion enthusiasts to consume according to their values and attitudes.
  5. The trend toward sustainable luxury continues: Sustainability as a means of distinction for a new form of luxury enables alternative manufacturing processes and innovative materials in the luxury fashion market. These are being showcased by an avant-garde and, if they prove successful, adapted by fast fashion.

OEKO-TEX® Association celebrates 30th birthday

The international OEKO-TEX® Association, which consists of a total of 17 independent research and testing institutes in Europe and Japan, turns thirty this year. As one of the founding members, OETI is taking this as an opportunity to talk to OEKO-TEX® expert Helene Melnitzky (Head of the Ecology Department at OETI) about the role of the OEKO-TEX® Association, market trends and current OEKO-TEX® certifications and labels.

The international OEKO-TEX® Association, which consists of a total of 17 independent research and testing institutes in Europe and Japan, turns thirty this year. As one of the founding members, OETI is taking this as an opportunity to talk to OEKO-TEX® expert Helene Melnitzky (Head of the Ecology Department at OETI) about the role of the OEKO-TEX® Association, market trends and current OEKO-TEX® certifications and labels.

The international OEKO-TEX® Association is celebrating its thirtieth anniversary this year. What role has it played so far with regard to the product safety of textile and leather products?
Helene Melnitzky:
In the area product safety1, OEKO-TEX® has had a great impact over the last three decades by ensuring certain pollutant additives, some of which were found in large quantities in textiles 30 years ago, no longer exist. The OEKO-TEX® Association was also the first to limit certain heavy metals. Based on our actions, legal provisions were ultimately passed. We have been testing banned dyes since before there even was an EU regulation in this regard. Of course, we now test according to the EU regulation, but in this respect OEKO-TEX® was a clear trailblazer.

In addition to product safety, OEKO-TEX® has been working on the topics of ‘environmentally friendly textile products manufactured under fair working conditions for 30 years, which also included leather products for the last five years, and with STeP by OEKO-TEX® on the ‘certification of environmentally friendly production sites’ since 2013. In one way or another, we have been preparing the market for thirty years. In the process, we are always creating new things: currently the Impact Calculator and, in autumn-2022, a new certification for brands and retailers: RESPONSIBLE BUSINESS by OEKO-TEX®.

How does that benefit the customers of OEKO-TEX®?
Helene Melnitzky:
Customers can use these calculations for external communication to demonstrate on their products or webpages that their products have a lower footprint than their competitors. This means that customers sourcing everything regionally will have a smaller footprint than companies that source products from different countries. In the future, it will be necessary to display the water and carbon footprint on the product, so that consumers can decide whether they want to buy product A or B.

How is the aspect of fair working conditions taken into account?
Helene Melnitzky:
This topic has also been gaining significant momentum over the last ten years. There is now enough pressure on brands and retailers to improve local working conditions. We cover this area as part of our STeP by OEKO-TEX® certification2 with our ‘social responsibility’ module. The advantage for our customers is that they can subsequently use the MADE IN GREEN by OEKO-TEX® label to show how they have performed in the social module.

What does Transparency with MADE IN GREEN by OEKO-TEX® mean?
Helene Melnitzky:
Everything that is written on the product is transparent. The MADE IN GREEN by OEKO-TEX® label is a traceable product label for all types of textiles and leather items that have been produced in environmentally friendly factories and at safe and socially responsible workplaces. Furthermore, the MADE IN GREEN by OEKO-TEX® label gives consumers the certainty that the textile or leather product is made from materials tested for harmful substances. In order to ensure that textile or leather products with the MADE IN GREEN by OEKO-TEX® label have been produced using environmentally friendly processes under socially acceptable working conditions, manufacturing and wet production sites must be certified according to STeP by OEKO-TEX®.

For a year now, it has been possible to have recycled materials STANDARD 100 certified and display that certification as a hangtag to communicate that the product consists of a certain proportion3 of recycled materials. Which market demand is this certification addressing?
Helene Melnitzky:
There is an increasing demand that at least part of the product must be made from recycled material. This is partly attributable to market pressure because raw materials are scarce and expensive. However, we are also voluntarily informing consumers about recycling as part of the circular economy.

What is your outlook for the next few years?
Helene Melnitzky:
Producing textile and leather products in a more environmentally friendly and fair manner, while making the value chain more transparent, is a global challenge that sets new environmental standards. In the long term, however, it also involves important economic and social aspects. The goal is to raise awareness of these interdependencies and a common understanding of environmental issues – among producers and, of course, end consumers. It is clear that the demand for certified and traceable products is growing among consumers. This trend is reflected in purchasing behaviour and thus in manufacturing. Nevertheless, there’s still a lot to do.
