In this project, FET will be working with the University of Manchester to conduct computational fluid dynamics (CFD) studies on a number of complex spin pack and spinneret designs. The aim of this work is to identify areas of improvement for FET’s spin packs and spinnerets and to use computer aided designs to develop significantly more efficient versions. The goal is that the research will improve the throughput of FET extrusion systems, thus reducing the amount of polymer lost through inefficient flow paths. This development, in turn, will reduce the environmental impact of synthetic polymer processing.

FET designs, develops, and manufactures extrusion equipment for a range of high value textile material applications worldwide. Established in 1998, FET’s major strength has always been to collaborate with customers in testing, evaluating and developing high value materials with diverse, functional properties. Efficiency and sustainability are key, so enhanced development of spinneret technology will contribute significantly to these objectives.

DITF: Recyclable event and trade fair furniture made of paper

A lot of waste is generated in the trade fair and event industry. It makes sense to have furniture that can quickly be dismantled and stored to save space - or simply disposed of and recycled. Paper is the ideal raw material here: locally available and renewable. It also has an established recycling process. The German Institutes of Textile and Fiber Research (DITF) and their project partners have jointly developed a recycling-friendly modular system for trade fair furniture. The "PapierEvents" project was funded by the German Federal Environmental Foundation (DBU).

Once the paper has been brought into yarn form, it can be processed into a wide variety of basic elements using the structure winding process, creating a completely new design language.

The German Institutes of Textile and Fiber Research (DITF) and their project partners have jointly developed a recycling-friendly modular system for trade fair furniture. The "PapierEvents" project was funded by the German Federal Environmental Foundation (DBU).

Once the paper has been brought into yarn form, it can be processed into a wide variety of basic elements using the structure winding process, creating a completely new design language.

The unusual look is created in the structure winding process. In this technology developed at the DITF, the yarn is deposited precisely on a rotating mandrel. This enables high process speeds and a high degree of automation. After the winding process, the individual yarns are fixed, creating a self-supporting component. A starch-based adhesive, which is also made from renewable and degradable raw materials, was used in the project for the fixation.

The recyclability of all the basic elements developed in the project was investigated and confirmed. For this purpose the research colleagues at the project partner from the Department of Paper Production and Mechanical Process Engineering at TU Darmstadt (PMV) used the CEPI method, a new standard test procedure from the Confederation of European Paper Industries.

Sensor and lighting functions were also implemented in a recycling-friendly manner. The paper sensor yarns are integrated into the components and detect contact.

Also, a modular system for trade fair and event furniture was developed. The furniture is lightweight and modular. For example, the total weight of the counter shown is well under ten kilograms and individual parts can easily be shipped in standard packages. All parts can be used several times, making them suitable for campaigns lasting several weeks.

A counter, a customer stopper in DIN A1 format and a pyramid-shaped stand were used as demonstrators. The research work of the DITF (textile technology) and PMV (paper processing) was supplemented by other partners: GarnTec GmbH developed the paper yarns used, the industrial designers from quintessence design provided important suggestions for the visual and functional design of the elements and connectors and the event agency Rödig GmbH evaluated the ideas and concepts in terms of usability in practical use.

Artificial intelligence to help remove PFAS

A new research project links some of Denmark's leading researchers in PFAS remediation with artificial intelligence. The goal is to develop and optimise a new form of wastewater and drinking water treatment technology using artificial intelligence for zero-pollution goals.

In a new research and development project, researchers from Aarhus University aim to develop a new technology that can collect and break down perpetual chemicals (PFAS) in one step in a purification process that can be connected directly to drinking water wells and treatment plants.

The project has received funding from the Villum Foundation of DKK 3 million, and it will combine newly developed treatment technology from some of Denmark's leading PFAS remediation researchers with artificial intelligence that can ensure optimal remediation.

The project has received funding from the Villum Foundation of DKK 3 million, and it will combine newly developed treatment technology from some of Denmark's leading PFAS remediation researchers with artificial intelligence that can ensure optimal remediation.

"In the project, we will design, construct and test a new, automated degradation technology for continuous PFAS degradation. We’re also going to set up an open database to identify significant and limiting factors for degradation reactions with PFAS molecules in the reactor," says Associate Professor Xuping Zhang from the Department of Mechanical and Production Engineering at Aarhus University, who is co-heading the project in collaboration with Associate Professor Zongsu Wei from the Department of Biological and Chemical Engineering.

Ever since the 1940s, PFAS (per- and polyfluoroalkyl substances) have been used in a myriad of products, ranging from raincoats and building materials to furniture, fire extinguishers, solar panels, saucepans, packaging and paints.

However, PFAS have proven to have a number of harmful effects on humans and the environment, and unfortunately the substances are very difficult to break down in nature. As a result, the substances continuously accumulate in humans, animals, and elsewhere in nature.

In Denmark, PFAS have been found in drinking water wells, in surface foam on the sea, in the soil at sites for fire-fighting drills, and in many places elsewhere, for example in organic eggs. It is not possible to remove PFAS from everything, but work is underway to remove PFAS from the groundwater in drinking water wells that have been contaminated with the substances.

Currently, the most common method to filter drinking water for PFAS is via an active carbon filter, an ion-exchange filter, or by using a specially designed membrane. All of these possibilities filter PFAS from the water, but they do not destroy the PFAS. The filters are therefore all temporary, as they have to be sent for incineration to destroy the accumulated PFAS, or they end in landfills.

The project is called 'Machine Learning to Enhance PFAS Degradation in Flow Reactor', and it aims to design and develop an optimal and permanent solution for drinking water wells and treatment plants in Denmark that constantly captures and breaks down PFAS, while also monitoring itself.

"We need to be creative and think outside the box. I see many advantages in linking artificial intelligence with several different water treatment technologies, but integrating intelligence-based optimisation is no easy task. It requires strong synergy between machine learning and chemical engineering, but the perspectives are huge," says Associate Professor Zongsu Wei from the Department of Biological and Chemical Engineering at Aarhus University.

Fashion for Good addresses challenges of sorting for rewearable textiles

Fashion for Good's Sorting for Circularity framework expands to address the challenge of ensuring rewearable textiles remain in use as opposed to finding their way into global waste streams or landfills. This 18-month project tests automated sorting technologies using artificial intelligence and machine learning to optimise the sorting of rewearable garments and enable greater circularity.

This project will test automated sorting technologies using machine learning and artificial intelligence (AI) to collect product information — such as colour, style, garment type, and quality. This will enable sorters and brands to make better decisions and sort efficiently based on product data and criteria from local, European, and export resale market requirements, thus optimising the flow of textiles to achieve their highest value potential.

To ensure accuracy and representation in capturing data on the flow of textiles within the EU and export markets, this project will focus on specific geographical regions: Lithuania (Nordic/Baltic), the Netherlands (Western), Poland (Central-Eastern), and Spain (Southern Europe).

The conference will showcase the most successful cellulose-based solutions currently on the market or those planned for the near future.

The nominees:

The Straw Flexi-Dress: Design Meets Sustainability – DITF & VRETENA (DE)
The Flexi-Dress design was inspired by the natural golden colour and silky touch of HighPerCell® (HPC) filaments based on unbleached straw pulp. These cellulose filaments are produced using environmentally friendly spinning technology in a closed-loop production process. The design decisions focused on the emotional connection and attachment to the HPC material to create a local and circular fashion product. The Flexi-Dress is designed as a versatile knitted garment – from work to street – that can be worn as a dress, but can also be split into two pieces – used separately as a top and a straight skirt. The top can also be worn with the V-neck front or back. The HPC textile knit structure was considered important for comfort and emotional properties.

HONEXT® Board FR-B (B-s1, d0) – Flame-retardant Board made From Upcycled Fibre Waste From the Paper Industry – Honext Material (ES)
HONEXT® FR-B board (B-s1, d0) is a flame-retardant board made from 100 % upcycled industrial waste fibres from the paper industry. Thanks to innovations in biotechnology, paper sludge is upcycled – the previously “worthless” residue from paper making – to create a fully recyclable material, all without the use of resins. This lightweight and easy-to-handle board boasts high mechanical performance and stability, along with low thermal conductivity, making it perfect for various applications in all interior environments where fire safety is a priority. The material is non-toxic, with no added VOCs, ensuring safety for both people and the planet. A sustainable and healthy material for the built environment, it achieves Cradle-to-Cradle Certified GOLD, and Material Health CertificateTM Gold Level version 4.0 with a carbon-negative footprint. Additionally, it is verified in the Product Environmental Footprint.

LENZING™ Cellulosic Fibres for Glacier Protection – Lenzing (AT)
Glaciers are now facing an unprecedented threat from global warming. Synthetic fibre-based geotextiles, while effective in slowing down glacier melt, create a new environmental challenge: microplastics contaminating glacial environments. The use of such materials contradicts the very purpose of glacier protection, as it exacerbates an already critical environmental problem. Recognizing this problem, the innovative use of cellulosic LENZING™ fibres presents a pioneering solution. The Institute of Ecology, at the University of Innsbruck, together with Lenzing and other partners made first trials in 2022 by covering small test fields with LENZING™ fibre-based geotextiles. The results were promising, confirming the effectiveness of this approach in slowing glacier melt without leaving behind microplastic.

The RENU Jacket – Advanced Recycling for Cellulosic Textiles – Pangaia (UK) & Evrnu (US)
PANGAIA LAB was born out of a dream to reduce barriers between people and the breakthrough innovations in material science. In 2023, PANGAIA LAB launched the RENU Jacket, a limited edition product made from 100% Nucycl® – a technology that recycles cellulosic textiles by breaking them down to their molecular building blocks, and reforming them into new fibres. This process produces a result that is 100% recycled and 100% recyclable when returned to the correct waste stream – maintaining the strength of the fibre so it doesn’t need to be blended with virgin material.
Through collaboration with Evrnu, the PANGAIA team created the world’s first 100% chemically recycled denim jacket, replacing a material traditionally made from 100% virgin cotton. By incorporating Nucycl® into this iconic fabric construction, dyed with natural indigo, the teams have demonstrated that it’s possible to replace ubiquitous materials with this innovation.

Textiles Made from Easy-to-dye Biocelsol – VTT Technical Research Centre of Finland (FI)
One third of the textile industry’s wastewater is generated in dyeing and one fifth in finishing. But the use of chemically modified Biocelsol fibres reduces waste water. The knitted fabric is made from viscose and Biocelsol fibres and is only dyed after knitting. This gives the Biocelsol fibres a darker shade, using the same amount of dye and no salt in dyeing process. In addition, an interesting visual effect can be achieved. Moreover, less dye is needed for the darker colour tone in the finished textile and the possibility to use the salt-free dyeing is more environmentally friendly.
These special properties of man-made cellulosic fibres will reassert the fibres as a replacement for the existing fossil-based fibres, thus filling the demand for more environmentally friendly dyeing-solutions in the textile industry. The functionalised Biocelsol fibres were made in Finnish Academy FinnCERES project and are produced by wet spinning technique from the cellulose dope containing low amounts of 3-allyloxy-2-hydroxypropyl substituents. The functionality formed is permanent and has been shown to significantly improve the dyeability of the fibres. In addition, the functionalisation of Biocelsol fibres reduces the cost of textile finishing and dyeing as well as the effluent load.

A New Generation of Bio-based and Resource-efficient Fibre – TreeToTextile (SE)
TreeToTextile has developed a unique, sustainable and resource efficient fibre that doesn't exist on the market today. It has a natural dry feel similar to cotton and a semi-dull sheen and high drape like viscose. It is based on cellulose and has the potential to complement or replace cotton, viscose and polyester as a single fibre or in blends, depending on the application.
TreeToTextile Technology™ has a low demand for chemicals, energy and water. According to a third party verified LCA, the TreeToTextile fibre has a climate impact of 0.6 kg CO2 eq/kilo fibre. The fibre is made from bio-based and traceable resources and is biodegradable.

Long-lived lamellas for reinforcing buildings

Carbon fiber-reinforced polymer lamellas are an innovative method of reinforcing buildings. There are still many unanswered questions regarding their recycling, however. A research project by Empa's Mechanical Systems Engineering lab is now set to provide answers. Thanks to the support from a foundation, the project could now be launched.

The construction sector is responsible for around 60 percent of Switzerland's annual waste. The industry's efforts to recycle demolition materials are steadily increasing. Nevertheless, there are still end-of-life materials that, for the time being, cannot be reused as recycling would be too time-consuming and expensive. One of these are carbon fiber-reinforced polymer (CFRP) lamellas.

Nevertheless, there are still end-of-life materials that, for the time being, cannot be reused as recycling would be too time-consuming and expensive. One of these are carbon fiber-reinforced polymer (CFRP) lamellas.

Making buildings "live" longer
The reinforcing method developed by Urs Meier, former Empa Director at Dübendorf, has been used in infrastructure construction for 30 years. CFRP lamellas are attached with epoxy adhesive to bridges, parking garages, building walls and ceilings made of concrete or masonry. As a result, the structures can be used for 20 to 30 years longer. The method is increasingly being applied worldwide – mainly because it massively improves the earthquake resistance of masonry buildings.

"By significantly extending the lifespan of buildings and infrastructure, CFRP lamellas make an important contribution to increasing sustainability in the construction sector. However, we need to find a way how we can further use CFRP lamellas after the buildings are being demolished," explains Giovanni Terrasi, Head of the Mechanical Systems Engineering lab at Empa. To achieve this, he wants to develop a method for recycling CFRP lamellas. Convinced by this idea, a foundation supported it with a generous donation. The project officially launched in October.

Gentle separation
First, a mechanical process will be developed to detach the CFRP lamellas from the concrete without damaging them. Initial tests at Empa are encouraging: After the lamellas were separated from the concrete, they still had a strength of 95 percent – even if they had already been used for 30 years.

Then, the demolished CFRP lamellas shall be used to produce reinforcement for prefabricated components. Terrasi's goal: saving thousands of tons of CFRP lamellas from ending up in landfills after the demolition of old concrete structures and reuse them in low-CO2 concrete elements. After completion of the project, Giovanni Terrasi and his team – consisting of Zafeirios Triantafyllidis, Valentin Ott, Mateusz Wyrzykowski and Daniel Völki – want to produce railroad sleepers from recycled concrete, which will be reinforced and prestressed with demolition CFRP lamellas. This would give the "waste-to-be" material a second life in Swiss infrastructure construction.

Vesta Corporation: First Sustainability Report

The Tuscan tannery Vesta Corporation has presented to its stakeholders a report outlining its current commitment and future objectives, with a view to innovating, safeguarding and fostering high-end leather material processing.

Ever since it was founded in 1966 in Ponte a Egola, the Tuscan hub for the production of leather for vegetable tanned soles, Vesta has been a supplier and partner of haute couture and sportswear brands, from lightweight calf and half-calf leather, to heavy leathers made with hind and rump hide, for leatherware and shoes.

The Tuscan tannery Vesta Corporation has presented to its stakeholders a report outlining its current commitment and future objectives, with a view to innovating, safeguarding and fostering high-end leather material processing.

Ever since it was founded in 1966 in Ponte a Egola, the Tuscan hub for the production of leather for vegetable tanned soles, Vesta has been a supplier and partner of haute couture and sportswear brands, from lightweight calf and half-calf leather, to heavy leathers made with hind and rump hide, for leatherware and shoes.

To draft this Report, reference was made to the “Global Reporting Initiative Sustainability Reporting Standards” established by the Global Reporting Initiative (GRI). The information in the balance sheet refers to the year 2022 (from 1 January to 31December 2022). Wherever possible, data for the previous year are included, to allow for a comparison of data over time and to assess the trend of Vesta activities. Sustainability is an objective-driven process. This means that comparing data allows for concretely measuring the company’s progress, as it pursues this accounting process year after year.

The improvement actions already implemented by Vesta involve corporate responsibility from an environmental, social and governance perspective. An example are the improved heating and processing plants (which entails the construction of a new tumbling department based on 4.0 technology). This guarantees significant energy, water and economic savings. Along with numerous corporate certifications, the company has passed the Raw Material Traceability test with a score of EXCELLENT, as well as the Carbon and Water footprint analysis.

As confirmation of its commitment to improving corporate performance levels, Vesta has been upgraded from BRONZE (2020) to GOLD in 2023, as assessed by the Leather Working Group (which measures leather manufacturers’ environmental performance for ecological production and for a systemic management of quality, environmental, safety and ethical factors).

Becoming energy-independent is a major step in the pipeline, involving the installation of a photovoltaic plant. This is complemented by the implementation of a project aimed at totally compensating its CO2 emissions for the year subject to accounting and certification. This neutrality will be achieved through the acquisition of credits deriving from projects certified by the United Nations. For example, with the construction of an important hydro-electric plant to which Vesta is contributing. With regard to production, corporate research is currently focused on developing solutions to reduce water and energy use. It is also implementing circular trends by adopting an increasing number of bio-based products, to guarantee the most sustainable end-of-life and waste management for its products.

Research to reduce shed of microplastics during laundering

A collaboration between Deakin University researchers and Australia’s largest commercial linen supplier Simba Global is tackling a critical global issue, the spread of harmful microplastics through our laundry.

Clothing and textiles are estimated to generate up to 35 per cent of the microplastics found in the world’s oceans, making them one of the biggest contributors. But there is still a lot to be learnt about the characteristics of these microplastics and exactly how and why they are generated.

Researchers at the ARC Research Hub for Future Fibres in Deakin’s Institute for Frontier Materials (IFM) have teamed up with Simba Global, a global textile manufacturing and supply company, to better understand the extent and type of microplastics shed when their products are laundered. Simba Global wants to lead the charge to reduce the environmental impact of textiles.

Lead scientist IFM Associate Professor Maryam Naebe said working with an industry partner on the scale of Simba Global meant the research could have a huge real-world impact.

Simba Global wants to lead the charge to reduce the environmental impact of textiles.

Lead scientist IFM Associate Professor Maryam Naebe said working with an industry partner on the scale of Simba Global meant the research could have a huge real-world impact.

Simba Global is the major linen supplier to Australia’s hospitals, hotels and mining camps, resulting in 950,000 tonnes of textile products – including bedsheets, bath towels, scrubs and much more – going through the commercial laundering process each year. It also supplies international markets in New Zealand, Singapore and the US.

“As part of our research, we will investigate potential solutions including the pre-treatment of textiles to reduce the shedding of microplastics, or even increasing the size of the plastics that break down so they can be better captured and removed by filtration during the laundering process,” Associate Professor Naebe said.

“Microplastics are now ubiquitous in the environment, they’re in the air we breathe, the food we eat and the earth we walk on. The magnitude of the problem is bigger than previously thought.

“Of serious concern is the mounting evidence that microplastics are having a negative impact on human and animal health. There are not just physical, but chemical and biological impacts.”

Associate Professor Naebe’s team have taken the first steps in the project, analysing wastewater samples from commercial laundries with high-powered electron microscopes in their Geelong laboratory, part of the largest fibres and textiles research facility in Australia.

The team recently presented a new scientific paper at the Association of Universities for Textiles (AUTEX) Conference 2023, which started the important process of formally categorising these types of microplastics, as well as developing standard terminology and testing methods.

“Because our understanding of microplastics is still in its infancy, we needed to start right at the beginning,” Associate Professor Naebe said.

“We need to have a standard definition of what is a microplastic. Up to this point that has been lacking, which makes it difficult to compare and incorporate other studies in this area.

“We are now developing a systematic method for sampling and identifying microplastics in laundry wastewater. It has been tricky to measure the different sizes, but this is important information to have. For example, there are studies that suggest some sizes of microplastics are causing more issues in certain animals.

“The next step will be establishing an essential method to prevent the release of microplastics from textile laundering. This may involve a coating on the surface of the textile or better ways to collect the waste during the washing process.”

Simba Global Executive Chair Hiten Somaia said the company had a strong focus on sustainability, driven by the business’ purpose statement.

“We are proud to partner with Deakin University in what is the first significant research into textile microplastic pollution in Australia. What we are most excited about is sharing the results of this research with all other textile markets in Australia – including clothing – and putting an end to microplastic pollution from textiles.”

HeiQ presents a complete set of tailored textile technologies that is said to improve the sleeping environment: "Unlocking Better Sleep". Therefore, HeiQ introduces a range of innovative products designed to enhance the quality of a comfortable night’s rest through sustainable and biobased solutions.

According to a recent study by the School of Architecture, Victoria University of Wellington (New Zealand), “individuals spend more than 50% of their time at home in the bedroom”. Another research from the Fatigue Countermeasures Laboratory, NASA Ames Research Center (United States), concluded that “sleep is critical to health and daytime functioning. For individuals to achieve optimal sleep, they must have access to a sleep environment that allows them to achieve quality sleep.” These are strong indicators that we should treat sleep with the highest importance that it deserves.

The flagship products leading this positive change are the 100% biobased cosmetic technology HeiQ Skin Care, the plant-based deodorizer HeiQ Mint (botanical freshness), the dual action cooling solution HeiQ Cool, and HeiQ Allergen Tech that reduces exposure to inanimate allergens through active probiotics. These biobased innovations are set to redefine the sleep experience and contribute to overall well-being.

HeiQ Skin Care is the most recent addition to HeiQ’s portfolio - a synbiotic textile finish promoting a balanced microbiome for glowing skin. Unlike conventional products, HeiQ Skin Care utilizes pre- and probiotics integrated into a biobased matrix, offering long-lasting cosmetic benefits. It is particularly suited for products that are in direct and long contact with skin, such as pillowcases, duvet covers or bed sheets, acting as a cosmetic care session during sleep.

With CARBIOS' aim to optimize and continuously improve its unique enzymatic PET depolymerization technology, the 4-year7 OPTI-ZYME project aims to investigate the scientific and technical levers for improving the competitiveness of the process, optimizing the necessary investments and reducing its environmental footprint.

This collaborative R&D program focuses on the technical and economic optimization of process stages, while preserving the quality of the monomers obtained. These optimizations, new developments and the exploration of innovative solutions should enhance the technology's flexibility with regards to incoming waste. Raw materials could come from different sources that are currently rarely or not recycled, notably food trays and textiles, or a mix of incoming materials. It also aims to limit input and water consumption, as well as regenerate or reduce co-products and ultimate residual waste. Finally, it seeks to support enzyme optimization to maximize the process’ economic profitability and competitiveness.

The project therefore aims to achieve an overall improvement in performance, combining efficiency, quality and environmental sustainability, to benefit the Longlaville plant which is currently under construction, and future licensed plants.

In May 2023, CARBIOS, the project leader and coordinator, announced that it had been awarded a total of €11.4M in funding by the French State as part of France 2030, operated by ADEME, including €8.2M directly for CARBIOS (€3.2M in grants and €5M in repayable advances) and €3.2M for its academic partners INRAE, INSA and CNRS (via the TWB mixed service and TBI research units). This funding, which is made up of grants and repayable advances, will be paid out in several instalments over the course of the project, including an initial instalment of 15%, equivalent to €1.2 million, received by CARBIOS on 5 December 2023. The first Monitoring Committee with ADEME for the first key stage of the project will be held in February 2024 to validate the granting of the second instalment of funding.

This project 2282D0513-A is funded by the French State as part of France 2030 operated by ADEME.

New test kit for textile microfibre shedding

In cooperation with testing provider Hohenstein, Under Armour is launching a new fiber-shed test kit. It will help textile companies along the supply chain to develop lower shed materials during product development. The companies carry out the test themselves in-house using the test kit or can commission Hohenstein as a testing service provider.

The kit is a one-off purchase, after which users can buy additional materials from project partner James Heal. By using the new kit, Under Armour can reliably assess the quality and shed rate of the materials from suppliers.

For Hohenstein customers, the test kit is a useful addition to their microplastics tests. It is a quick and relatively inexpensive preliminary test that ensures better early-stage results for the end product.

During the production, wear and laundering of synthetic and natural fabrics, fibre shedding occurs in varying degrees. Hohenstein and Under Armour expect that their test method will help the industry better understand and reduce its contribution to the microfibre problem.

Self-driven and sustainable removal of oil spills in water using textiles

Researchers at the ITA, the University of Bonn and Heimbach GmbH have developed a new method for removing oil spills from water surfaces in an energy-saving, cost-effective way and without the use of toxic substances. The method is made possible by a technical textile that is integrated into a floating container. A single small device can remove up to 4 liters of diesel within an hour. This corresponds to about 100 m2 of oil film on a water surface.
 
Despite the steady expansion of renewable energies, global oil production, oil consumption and the risk of oil pollution have increased steadily over the last two decades. In 2022, global oil production amounted to 4.4 billion tons! Accidents often occur during the extraction, transportation and use of oil, resulting in serious and sometimes irreversible environmental pollution and harm to humans.

There are various methods for removing this oil pollution from water surfaces. However, all methods have various shortcomings that make them difficult to use and, in particular, limit the removal of oil from inland waters.

There are various methods for removing this oil pollution from water surfaces. However, all methods have various shortcomings that make them difficult to use and, in particular, limit the removal of oil from inland waters.

For many technical applications, unexpected solutions come from the field of biology. Millions of years of evolution led to optimized surfaces of living organisms for their interaction with the environment. Solutions - often rather unfamiliar to materials scientists and difficult to accept. The long-time routine examination of around 20,000 different species showed that there is an almost infinite variety of structures and functionalities. Some species in particular stand out for their excellent oil adsorption properties. It was shown that, e.g., leaves of the floating fern Salvinia molesta, adsorb oil, separate it from water surfaces and transport it on their surfaces (Figure 1, see also the video of the phenomon.).

The observations inspired them to transfer the effect to technical textiles for separating oil and water. The result is a superhydrophobic spacer fabric that can be produced industrially and is therefore easily scalable.

The bio-inspired textile can be integrated into a device for oil-water separation. This entire device is called a Bionic Oil Adsorber (BOA). Figure 2: Cross-section of computer-aided (CAD) model of the Bionic Oil Adsorber. The scheme shows an oil film (red) on a water surface (light blue). In the floating cotainer(gray), the textile (orange) is fixed so that it is in contact with the oil film and the end protrudes into the container. The oil is adsorbed and transported by the BOA textile. As shown in the cross-section, it enters the contain-er, where it is released again and accumulates at the bottom of the container. See also the video regarding the oil absorption on the textile, source ITA).
 
Starting from the contamination in the form of an oil film on the water surface, the separation and collection process works according to the following steps:

  • The BOA is introduced into the oil film.
  • The oil is adsorbed by the textile and separated from the water at the same time.
  • The oil is transported through the textile into the collection container.
  • The oil drips from the textile into the collection container.
  • The oil is collected until the container is emptied.

The advantage of this novel oil separation device is that no additional energy has to be applied to operate the BOA. The oil is separated from the surrounding water by the surface properties of the textile and transported through the textile driven solely by capillary forces, even against gravity. When it reaches the end of the textile in the collection container, the oil desorbs without any further external influence due to gravitational forces. With the current scale approximately 4 L of diesel can be separated from water by one device of the Bionic Oil Adsorber per hour.

  • It seems unlikely that a functionalized knitted spacer textile is cheaper than a conventional nonwoven, like it is commonly used for oil sorbents. However, since it is a functional material, the costs must be related to the amount of oil removed. In this respect, if we compare the sales price of the BOA textile with the sales prices of various oil-binding nonwovens, the former is 5 to 13 times cheaper with 10 ct/L oil removed.
    Overall, the BOA device offers a cost-effective and sustainable method of oil-water separation in contrast to conventional cleaning methods due to the following advantages:
  • No additional energy requirements, such as with oil skimmers, are necessary
  • No toxic substances are introduced into the water body, such as with oil dispersants
  • The textiles and equipment can be reused multiple times
  • No waste remains inside the water body
  • Inexpensive in terms of the amount of oil removed.
  • The team of researchers from the ITA, the University of Bonn and Heimbach GmbH was able to prove that the novel biomimetic BOA technology is surprisingly efficient and sustainable for a self-controlled separation and automatic collection of oil films including their complete removal from the water. BOA can be asapted for open water application but also for the use in inland waters. Furthermore, it is promising, that the textile can be used in various related separation processes. The product is currently being further developed so that it can be launched on the market in 2-3 years.

CarboScreen: Sensor monitoring for complex carbon fibre production

Felix Pohlkemper and Tim Röding from Institut für Textiltechnik (ITA) of RWTH Aachen University are developing a technology with their start-up CarboScreen GmbH that makes complex carbon fibre production controllable through sensor monitoring. With the help of CarboScreen technology, it should be possible to double the production speed from the current 15 m/min to 30 m/min in the medium term. The doubling of production speed alone could result in an increase in turnover of up to €37.5 million per year and production plant. Felix Pohlkemper and Tim Röding were awarded third place in the AVK Innovation Award 2023 in the Processes and Procedures category for this ground-breaking development. The award ceremony took place during the JEC Roof Forum in Salzburg, Austria.

The award ceremony took place during the JEC Roof Forum in Salzburg, Austria.

The production of carbon fibres is highly complex. In the current state of the art, however, the manufacturing process is only monitored manually by semi-skilled workers. However, even minimal fibre damage during production leads to a reduction in the quality of the carbon fibre. In extreme cases, it can also lead to plant fires. To ensure production quality, the production speed is currently limited to a maximum of 15 m/min. In fact, the production speed of the systems could be higher. The sensor-based online monitoring of Carbo-Screen makes it possible to increase the production speed to 30 m/min in the medium term. As a result of the increased production volume per system, the specific production costs of the carbon fibre are reduced, which can result in lower prices.

A reduced sales price would make it possible to use carbon fibres and their composite materials even more widely in traditional markets such as aerospace technology and wind energy, as well as for mass production in the automotive industry.

The CarboScreen online monitoring system is currently being developed for industrial use. It is to be validated at an industrial plant in 2024. CarboScreen GmbH was founded as part of EXIST funding and offers AI-supported sensor systems for carbon fibre production. The sensor technology continuously monitors the fibre throughout the entire production process. Deviations are detected automatically.

The winners of the AVK Innovation Award are honoured annually by the AVK Industrievereinigung Verstärkte Kunststoffe. Companies, institutes and their partners are honoured in three categories: products and applications, processes and procedures, and research and science.

Tampon for men aiming to reduce gender dysphoria

Tampon for Men by Finnish hygiene product brand Vuokkoset aims to alleviate the distress transgender men feel related to menstruation. The creative partner behind the idea is TBWA\Helsinki. The product was launched during the international Transgender Awareness Week and sparked a discussion in Scandinavia of the inclusivity of the health and wellness industry.

Research has shown that 93% of transgender men have experienced gender dysphoria related to menstruation. With a tampon designed for men, Vuokkoset sparked a vivid conversation in Finland during the International transgender awareness week (Nov 13 to 19, 2023) with an aim to change perceptions of menstruation and reduce the distress it causes to transgender men.

“Marketing has a huge role in shaping the world around us. As Finland’s leading creative agency and the leading global agency collective, we have an immense responsibility in actively making the world more inclusive. Vuokkoset is a brand that shares this value base and was brave enough to put the campaign together with us in just four short weeks” says Heidi Taina, creative director from TBWA\Helsinki.

Trans men and non-binary individuals may still have menstrual cycles, regardless of hormone therapy choices. This highlights the diversity in experiences related to menstruation among different gender identities.

"When I was young, menstruation felt not only strange but somehow wrong. Our culture does not really acknowledge the diversity of menstruating individuals" says DEI consultant and face of the campaign Dakota Robin, who has been through the gender affirming process himself.

The Tampon for Men will be available as a limited edition in Finland and wider distribution will begin in early 2024. Total sales proceeds are donated to Trasek ry, an organization focused on gender diversity and sexual health. A fully gender-neutral tampon product by Vuokkoset is also being considered.

"Menstrual products - from visuality, advertising to store location - are strongly feminine. It’s time to acknowledge the diversity of menstruating individuals" says Sanna Karhu, CEO of Delipap Oy, the company that manufactures Vuokkoset products.

"This is definitely a step in the right direction. By changing attitudes and broadening perspectives, we can also remove discrimination against gender minorities," concludes Dakota Robin.
