The production of new materials from fungi is an emerging research area. In a research project at the Swedish School of Textiles at the University of Borås, wet spinning of fungal cell wall material has shown promising results. In the project, fungi were grown on bread waste to produce textile fibers with potential in the medical technology field.

Sofie Svensson's project addresses, among other things, the UN's Global Goals 9, sustainable industry, innovation, and infrastructure, and Goal 12, sustainable consumption and production, as the project aimed to use sustainable methods in a resource- and cost-effective way, with less impact on people and the environment.

Sofie Svensson, who recently defended her dissertation in the field of Resource Recovery, explained:

“My research project is about developing fibres spun from filamentous fungi for textile applications. The fungi were grown on bread waste from grocery stores. Waste that would otherwise have a significant environmental impact if discarded.”

The novelty of the project lies in the method used – wet spinning of cell wall material.

“Wet spinning is a method used to spin fibres (filaments) from materials such as cellulose. In this project, cell wall material from filamentous fungi was used to produce fibres through wet spinning. The cell wall material from the fungi contains various polymers, mainly polysaccharides such as chitin, chitosan, and glucan. The challenge was to spin the material. It took some time initially before we found the right conditions”, explained Sofie Svensson.

Antibacterial properties
Filamentous fungi were cultivated in bioreactors to produce fungal biomass. Cell wall material was then isolated from the fungal biomass and used to spin a filament, which was tested for its suitability in medical applications.

“Tests of the fibers showed compatibility with skin cells and also indicated an antibacterial effect”, said Sofie Svensson, adding:

“In the method we worked with, we focused on using milder processes and chemicals. The use of hazardous and toxic chemicals is currently a challenge in the textile industry, and developing sustainable materials is important to reduce environmental impact.”

What is the significance of the results?
“New materials from fungi are an emerging research area. Hopefully, this research can contribute to the development of new sustainable materials from fungi”, explained Sofie Svensson.

Interest from the surrounding community has been significant during the project, and many have had a positive attitude toward the development of this type of material.

When will we see products made from these fibers?
“This particular method is at the lab scale and still in the research stage”, she explained.

The doctoral project was conducted within the larger research project Sustainable Fungal Textiles: A novel approach for reuse of food waste.

What is the next step in research on fungal fibers?
“Future studies could focus on optimizing the wet spinning process to achieve continuous production of fungal fibers. Additionally, testing the cultivation of fungi on other types of food waste.”

How have you experienced your time as a doctoral student in Resource Recovery?
“It has been an intense period as a doctoral student, and I have been really challenged and developed a lot.”

What is your next step?
“I will be taking parental leave for a while before taking the next step, which is yet to be decided.”

Sofie Svensson defended her dissertation on 14 June at the Swedish Centre for Resource Recovery, University of Borås.

Researchers have developed a method to make adaptive and eco-friendly sensors that can be directly and imperceptibly printed onto a wide range of biological surfaces, whether that’s a finger or a flower petal.

The method, developed by researchers from the University of Cambridge, takes its inspiration from spider silk, which can conform and stick to a range of surfaces. These ‘spider silks’ also incorporate bioelectronics, so that different sensing capabilities can be added to the ‘web’.

The fibres, at least 50 times smaller than a human hair, are so lightweight that the researchers printed them directly onto the fluffy seedhead of a dandelion without collapsing its structure. When printed on human skin, the fibre sensors conform to the skin and expose the sweat pores, so the wearer doesn’t detect their presence. Tests of the fibres printed onto a human finger suggest they could be used as continuous health monitors.

This low-waste and low-emission method for augmenting living structures could be used in a range of fields, from healthcare and virtual reality, to electronic textiles and environmental monitoring. The results are reported in the journal Nature Electronics.

Although human skin is remarkably sensitive, augmenting it with electronic sensors could fundamentally change how we interact with the world around us. For example, sensors printed directly onto the skin could be used for continuous health monitoring, for understanding skin sensations, or could improve the sensation of ‘reality’ in gaming or virtual reality application.

While wearable technologies with embedded sensors, such as smartwatches, are widely available, these devices can be uncomfortable, obtrusive and can inhibit the skin’s intrinsic sensations.

Last year, some of the same researchers showed that if the fibres used in smart textiles were coated with materials that can withstand stretching, they could be compatible with conventional weaving processes. Using this technique, they produced a 46-inch woven demonstrator display.

“If you want to accurately sense anything on a biological surface like skin or a leaf, the interface between the device and the surface is vital,” said Professor Yan Yan Shery Huang from Cambridge’s Department of Engineering, who led the research. “We also want bioelectronics that are completely imperceptible to the user, so they don’t in any way interfere with how the user interacts with the world, and we want them to be sustainable and low waste.”

There are multiple methods for making wearable sensors, but these all have drawbacks. Flexible electronics, for example, are normally printed on plastic films that don’t allow gas or moisture to pass through, so it would be like wrapping your skin in cling film. Other researchers have recently developed flexible electronics that are gas-permeable, like artificial skins, but these still interfere with normal sensation, and rely on energy- and waste-intensive manufacturing techniques.

3D printing is another potential route for bioelectronics since it is less wasteful than other production methods, but leads to thicker devices that can interfere with normal behaviour. Spinning electronic fibres results in devices that are imperceptible to the user, but don't have a high degree of sensitivity or sophistication, and they’re difficult to transfer onto the object in question.

Now, the Cambridge-led team has developed a new way of making high-performance bioelectronics that can be customised to a wide range of biological surfaces, from a fingertip to the fluffy seedhead of a dandelion, by printing them directly onto that surface. Their technique takes its inspiration in part from spiders, who create sophisticated and strong web structures adapted to their environment, using minimal material.

The researchers spun their bioelectronic ‘spider silk’ from PEDOT:PSS (a biocompatible conducting polymer), hyaluronic acid and polyethylene oxide. The high-performance fibres were produced from water-based solution at room temperature, which enabled the researchers to control the ‘spinnability’ of the fibres. The researchers then designed an orbital spinning approach to allow the fibres to morph to living surfaces, even down to microstructures such as fingerprints.

Tests of the bioelectronic fibres, on surfaces including human fingers and dandelion seedheads, showed that they provided high-quality sensor performance while being imperceptible to the host.

“Our spinning approach allows the bioelectronic fibres to follow the anatomy of different shapes, at both the micro and macro scale, without the need for any image recognition,” said Andy Wang, the first author of the paper. “It opens up a whole different angle in terms of how sustainable electronics and sensors can be made. It’s a much easier way to produce large area sensors.”

Most high-resolution sensors are made in an industrial cleanroom and require the use of toxic chemicals in a multi-step and energy-intensive fabrication process. The Cambridge-developed sensors can be made anywhere and use a tiny fraction of the energy that regular sensors require.

The bioelectronic fibres, which are repairable, can be simply washed away when they have reached the end of their useful lifetime, and generate less than a single milligram of waste: by comparison, a typical single load of laundry produces between 600 and 1500 milligrams of fibre waste.

“Using our simple fabrication technique, we can put sensors almost anywhere and repair them where and when they need it, without needing a big printing machine or a centralised manufacturing facility,” said Huang. “These sensors can be made on-demand, right where they’re needed, and produce minimal waste and emissions.”

The research was supported in part by the European Research Council, Wellcome, the Royal Society, and the Biotechnology and Biological Sciences Research Council (BBSRC), part of UK Research and Innovation (UKRI).

In a world first for the fashion industry, in October 2020 twelve pioneering players came together to break new ground by demonstrating a circular model for commercial garment production. Over more than three years, textile waste was collected and sorted, and regenerated into a new, man-made cellulosic fiber that looks and feels like cotton – a “new cotton” – using Infinited Fiber Company’s textile fiber regeneration technology.
 
The pioneering New Cotton Project launched in October 2020 with the aim of demonstrating a circular value chain for commercial garment production. Through-out the project the consortium worked to collect and sort end-of-life textiles, which using pioneering Infinited Fiber technology could be regenerated into a new man-made cellulosic fibre called Infinna™ which looks and feels just like virgin cotton. The fibres were then spun into yarns and manufactured into different types of fabric which were designed, produced, and sold by adidas and H&M, making the adidas by Stella McCartney tracksuit and a H&M printed jacket and jeans the first to be produced through a collaborative circular consortium of this scale, demonstrating a more innovative and circular way of working for the fashion industry.
 
As the project completes in March 2024, the consortium highlights eight key factors they have identified as fundamental to the successful scaling of fibre-to-fibre recycling.

The wide scale adoption of circular value chains is critical to success
Textile circularity requires new forms of collaboration and open knowledge exchange among different actors in circular ecosystems. These ecosystems must involve actors beyond traditional supply chains and previously disconnected industries and sectors, such as the textile and fashion, waste collection and sorting and recycling industries, as well as digital technology, research organisations and policymakers. For the ecosystem to function effectively, different actors need to be involved in aligning priorities, goals and working methods, and to learn about the others’ needs, requirements and techno-economic possibilities. From a broader perspective, there is also a need for a more fundamental shift in mindsets and business models concerning a systemic transition toward circularity, such as moving away from the linear fast fashion business models. As well as sharing knowledge openly within such ecosystems, it also is important to openly disseminate lessons learnt and insights in order to help and inspire other actors in the industry to transition to the Circular Economy.

Circularity starts with the design process
When creating new styles, it is important to keep an end-of-life scenario in mind right from the beginning. As this will dictate what embellishments, prints, accessories can be used. If designers make it as easy as possible for the recycling process, it has the bigger chance to actually be feedstock again. In addition to this, it is important to develop business models that enable products to be used as long as possible, including repair, rental, resale, and sharing services.

Building and scaling sorting and recycling infrastructure is critical
In order to scale up circular garment production, there is a need for technological innovation and infrastructure development in end-of-use textiles collection, sorting, and the mechanical pre-processing of feedstock. Currently, much of the textiles sorting is done manually, and the available optical sorting and identification technologies are not able to identify garment layers, complex fibre blends, or which causes deviations in feedstock quality for fibre-to-fibre recycling. Feedstock preprocessing is a critical step in textile-to-textile recycling, but it is not well understood outside of the actors who actually implement it. This requires collaboration across the value chain, and it takes in-depth knowledge and skill to do it well. This is an area that needs more attention and stronger economic incentives as textile-to-textile recycling scales up.

Improving quality and availability of data is essential
There is still a significant lack of available data to support the shift towards a circular textiles industry. This is slowing down development of system level solutions and economic incentives for textile circulation. For example, quantities of textiles put on the market are often used as a proxy for quantities of post-consumer textiles, but available data is at least two years old and often incomplete. There can also be different textile waste figures at a national level that do not align, due to different methodologies or data years. This is seen in the Dutch 2018 Mass Balance study reports and 2020 Circular Textile Policy Monitoring Report, where there is a 20% difference between put on market figures and measured quantities of post-consumer textiles collected separately and present in mixed residual waste. With the exception of a few good studies such as Sorting for Circularity Europe and ReFashion’s latest characterization study, there is almost no reliable information about fibre composition in the post-consumer textile stream either. Textile-to-textile recyclers would benefit from better availability of more reliable data. Policy monitoring for Extended Producer Responsibility schemes should focus on standardising reporting requirements across Europe from post-consumer textile collection through their ultimate end point and incentivize digitization so that reporting can be automated, and high-quality textile data becomes available in near-real time.

The need for continuous research and development across the entire value chain
Overall, the New Cotton Project’s findings suggest that fabrics incorporating Infinna™ fibre offer a more sustainable alternative to traditional cotton and viscose fabrics, while maintaining similar performance and aesthetic qualities. This could have significant implications for the textile industry in terms of sustainability and lower impact production practices. However, the project also demonstrated that the scaling of fibre-to-fibre recycling will continue to require ongoing research and development across the entire value chain. For example, the need for research and development around sorting systems is crucial. Within the chemical recycling process, it is also important to ensure the high recovery rate and circulation of chemicals used to limit the environmental impact of the process. The manufacturing processes also highlighted the benefit for ongoing innovation in the processing method, requiring technologies and brands to work closely with manufacturers to support further development in the field.

Thinking beyond lower impact fibres
The New Cotton Project value chain third party verified LCA reveals that the cellulose carbamate fibre, and in particular when produced with a renewable electricity source, shows potential to lower environmental impacts compared to conventional cotton and viscose. Although, it's important to note that this comparison was made using average global datasets from Ecoinvent for cotton and viscose fibres, and there are variations in the environmental performance of primary fibres available on the market. However, the analysis also highlights the importance of the rest of the supply chain to reduce environmental impact. The findings show that even if we reduce the environmental impacts by using recycled fibres, there is still work to do in other life cycle stages. For example; garment quality and using the garment during their full life span are crucial for mitigating the environmental impacts per garment use.
          
Citizen engagement
The EU has identified culture as one of the key barriers to the adoption of the circular economy within Europe. An adidas quantitative consumer survey conducted across three key markets during the project revealed that there is still confusion around circularity in textiles, which has highlighted the importance of effective citizen communication and engagement activities.

Cohesive legislation
Legislation is a powerful tool for driving the adoption of more sustainable and circular practices in the textiles industry. With several pieces of incoming legislation within the EU alone, the need for a cohesive and harmonised approach is essential to the successful implementation of policy within the textiles industry. Considering the link between different pieces of legislation such as Extended Producer Responsibility and the Ecodesign for Sustainable Products Regulation, along with their corresponding timeline for implementation will support stakeholders from across the value chain to prepare effectively for adoption of these new regulations.

The high, and continuously growing demand for recycled materials implies that all possible end-of-use textiles must be collected and sorted. Both mechanical and chemical recycling solutions are needed to meet the demand. We should also implement effectively both paths; closed-loop (fibre-to-fibre) and open -loop recycling (fibre to other sectors). There is a critical need to reconsider the export of low-quality reusable textiles outside the EU. It would be more advantageous to reuse them in Europe, or if they are at the end of their lifetime recycle these textiles within the European internal market rather than exporting them to countries where demand is often unverified and waste management inadequate.

Overall, the learnings spotlight the need for a holistic approach and a fundamental mindset shift in ways of working for the textiles industry. Deeper collaboration and knowledge exchange is central to developing effective circular value chains, helping to support the scaling of innovative recycling technologies and increase availability of recycled fibres on the market. The further development and scaling of collecting and sorting, along with the need to address substantial gaps in the availability of quality textile flow data should be urgently prioritised. The New Cotton Project has also demonstrated the potential of recycled fibres such as Infinna™ to offer a more sustainable option to some other traditional fibres, but at the same time highlights the importance of addressing the whole value chain holistically to make greater gains in lowering environmental impact. Ongoing research and development across the entire value chain is also essential to ensure we can deliver recycled fabrics at scale in the future.

The New Cotton Project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 101000559.

 

For the first time, researchers have used bacteria to “upcycle” waste polyethylene: Move over Spider-Man: Researchers at Rensselaer Polytechnic Institute have developed a strain of bacteria that can turn plastic waste into a biodegradable spider silk with multiple uses.

Their new study marks the first time scientists have used bacteria to transform polyethylene plastic — the kind used in many single-use items — into a high-value protein product.

That product, which the researchers call “bio-inspired spider silk” because of its similarity to the silk spiders use to spin their webs, has applications in textiles, cosmetics, and even medicine.

“Spider silk is nature’s Kevlar,” said Helen Zha, Ph.D., an assistant professor of chemical and biological engineering and one of the RPI researchers leading the project. “It can be nearly as strong as steel under tension. However, it’s six times less dense than steel, so it’s very lightweight. As a bioplastic, it’s stretchy, tough, nontoxic, and biodegradable.”

All those attributes make it a great material for a future where renewable resources and avoidance of persistent plastic pollution are the norm, Zha said.

Polyethylene plastic, found in products such as plastic bags, water bottles, and food packaging, is the biggest contributor to plastic pollution globally and can take upward of 1,000 years to degrade naturally. Only a small portion of polyethylene plastic is recycled, so the bacteria used in the study could help “upcycle” some of the remaining waste.

Pseudomonas aeruginosa, the bacteria used in the study, can naturally consume polyethylene as a food source. The RPI team tackled the challenge of engineering this bacteria to convert the carbon atoms of polyethylene into a genetically encoded silk protein. Surprisingly, they found that their newly developed bacteria could make the silk protein at a yield rivaling some bacteria strains that are more conventionally used in biomanufacturing.

The underlying biological process behind this innovation is something people have employed for millennia.

“Essentially, the bacteria are fermenting the plastic. Fermentation is used to make and preserve all sorts of foods, like cheese, bread, and wine, and in biochemical industries it’s used to make antibiotics, amino acids, and organic acids,” said Mattheos Koffas, Ph.D., Dorothy and Fred Chau ʼ71 Career Development Constellation Professor in Biocatalysis and Metabolic Engineering, and the other researcher leading the project, and who, along with Zha, is a member of the Center for Biotechnology and Interdisciplinary Studies at Rensselaer.

To get bacteria to ferment polyethylene, the plastic is first “predigested,” Zha said. Just like humans need to cut and chew our food into smaller pieces before our bodies can use it, the bacteria has difficulty eating the long molecule chains, or polymers, that comprise polyethylene.

In the study, Zha and Koffas collaborated with researchers at Argonne National Laboratory, who depolymerized the plastic by heating it under pressure, producing a soft, waxy substance. Next, the team put a layer of the plastic-derived wax on the bottoms of flasks, which served as the nutrient source for the bacteria culture. This contrasts with typical fermentation, which uses sugars as the nutrient source.

“It’s as if, instead of feeding the bacteria cake, we’re feeding it the candles on the cake,” Zha said.

Then, as a warming plate gently swirled the flasks’ contents, the bacteria went to work. After 72 hours, the scientists strained out the bacteria from the liquid culture, purified the silk protein, and freeze dried it. At that stage, the protein, which resembled torn up cotton balls, could potentially be spun into thread or made into other useful forms.

“What’s really exciting about this process is that, unlike the way plastics are produced today, our process is low energy and doesn’t require the use of toxic chemicals,” Zha said. “The best chemists in the world could not convert polyethylene into spider silk, but these bacteria can. We’re really harnessing what nature has developed to do manufacturing for us.”

However, before upcycled spider silk products become a reality, the researchers will first need to find ways to make the silk protein more efficiently.

“This study establishes that we can use these bacteria to convert plastic to spider silk. Our future work will investigate whether tweaking the bacteria or other aspects of the process will allow us to scale up production,” Koffas said.

“Professors Zha and Koffas represent the new generation of chemical and biological engineers merging biological engineering with materials science to manufacture ecofriendly products. Their work is a novel approach to protecting the environment and reducing our reliance on nonrenewable resources,” said Shekhar Garde, Ph.D., dean of RPI’s School of Engineering.

The study, which was conducted by first author Alexander Connor, who earned his doctorate from RPI in 2023, and co-authors Jessica Lamb and Massimiliano Delferro with Argonne National Laboratory, is published in the journal “Microbial Cell Factories.”

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.

“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.

With its high-quality technical narrow textiles, JUMBO-Textil stands for high-tech - whether woven, braided or knitted. As an elastic specialist and solution partner, the company develops and produces individual innovations for customers worldwide. The 70-strong team must be as diverse and flexible as the products it designs. Textination spoke to industrial engineer Carl Mrusek about the current challenges facing family businesses. Carl Mrusek, who has been Chief Sales Officer (CSO) at Textation Group GmbH & Co. KG, to which JUMBO-Textil belongs, for almost a year now, is in charge of strategic corporate development as well as other areas of responsibility.

 

"In a family business, tradition is the foundation, innovation is the way forward," they say. The image of family-run companies has changed significantly in recent years - old-fashioned values and outdated business concepts have given way to a strong corporate culture, a strong sense of regional responsibility and sustainable planning. How does JUMBO-Textil combine its corporate values and traditions with a contemporary management style?

Carl Mrusek: As a family business, there is a close bond between the employees and the company and vice versa; the continuity of human relationships is important and valuable. JUMBO-Textil also has a tradition of one thing in particular: contemporary corporate management, both technically and professionally, as well as in terms of management style and values. Especially in a family business, which is often managed by the same person for decades, it is crucial to question corporate values and management style and to promote change. A company that has been operating successfully internationally for almost 115 years must be adaptable. For us, reacting quickly to changes, even anticipating them and moving forward accordingly, is at the heart of smart business practices. The specialization in elastics in the 1920s is an example of the foresighted power of change, as is the strategically important turn to technical textiles in the 1970s. A recent example is the merger with vombaur under the umbrella of the Textation Group.

The most important thing in any company is its employees. We would not be able to attract and retain them with outdated traditions and working methods. For us, the focus is not on the company management, but on joint success, and in a complex world, this is usually the result of successful cooperation and not an announcement from the boss. Leadership clearly means setting and pursuing strategic goals, but today it also means team development. Finding the best people, bringing them together and motivating them to achieve the goal.

 

Team spirit and vision development: How do you achieve this at JUMBO-Textil?

Carl Mrusek: As a team! JUMBO-Textil has systematically expanded its management team. In addition to the Managing Director, our CEO Andreas Kielholz, the Chief Operational Officer Patrick Kielholz, the Chief Financial Officer Ralph Cammerath, the Chief Technology Officer Dr. Sven Schöfer and myself as Chief Sales Officer work here. This shows that we are convinced of the idea of cooperation: We also work together on corporate development and strategic issues. The same applies to the individual teams - in organizational specialist teams or in interdisciplinary project teams. The tasks for which we are responsible may be different, but each is equally important.

 

Is that why you start the introduction of contact persons on your website with the Junior Sales Manager? And the C-level representatives are at the end?

Carl Mrusek: Yes, all JUMBO-Textil heads are the head of the company for us. All JUMBO-Textil faces represent the company. This is also reflected in the order of the contact persons on the website. Visitors should be able to quickly find the person who can help them and not find out who runs the company. That's what the legal notice is for. (laughs)

 

What is JUMBO-Textil's mission statement and vision for the future, and what needs to change in order to achieve this vision?

Carl Mrusek: We are currently working on the strategic direction of the Textation Group, which JUMBO-Textil GmbH & Co. KG and vombaur GmbH & Co. KG are part of. In this context, we have developed the Group's corporate vision and mission and updated our mission statement. This serves as a foundation for strategy development and is only sustainable if employees are involved in this process through surveys and workshops. I don't want to give too much away yet, but this much is already clear: strong teams, the right people in the right place, taking responsibility at all levels, sustainability as the basis for innovation - these will be the four cornerstones. You can already see from this: To achieve our vision, we cannot flip a switch. We must always remain open to change, always new - from product development to personnel recruitment. But as I said, we have a tradition of doing this.

 

JUMBO-Textil is not an industry specialist, but combines expertise for demanding high-tech narrow textiles. Who is in charge of challenging customer projects - do you decide in a team or rather top-down, where is the responsibility for an order placed?

Carl Mrusek: As a team, we decide which projects to implement and how to prioritize them. The corporate strategy determines the "direction of travel". In addition to the sales side, the development side of new projects also plays a decisive role. I therefore coordinate intensively with Dr. Sven Schöfer (CTO) and his team, as the focus here is on the technical development and implementation of our products. In the end, project processing is always a team effort between Sales and Development in close cooperation with Production..

 

Between above-standard pay, a 4-day week and the much-vaunted work-life balance in the current situation on the job market, companies are more likely to be in the position of applicants than vice versa. What are you doing to remain attractive as an employer for new colleagues? And how do you keep the enthusiasm of your skilled employees at a consistently high level?

Carl Mrusek: An important approach for us is education. Training young people and proving to them during their apprenticeship: JUMBO-Textil is your place to be. We therefore already start recruiting skilled workers through our school visits and school internships. As a state-of-the-art company, we offer an attractive salary level and a pleasant and healthy working environment.

Applicants today also often want to organize their working hours and work arrangements individually and flexibly, for a variety of reasons. With modern working models and thanks to our ongoing progress in digitalization, we support them wherever possible. People also want to work for a company that they can identify with. Environmental and climate protection are just as important to our employees and applicants as social standards in our supply chain. The fact that we have set ourselves ambitious goals with our sustainability strategy and are consistently pursuing them with firmly scheduled steps - our climate-neutral energy generation is a concrete example that has already been implemented. Furthermore, we vigorously encourage our business partners to respect human and employee rights and are committed to the Code of Conduct of the German textile and fashion industry. All of this helps us to recruit staff.

 

What larger, more capital-intensive companies can partially make up for with financial resources, SMEs have to manage through agility and adaptability - especially in situations of crisis. To what extent are these requirements also reflected in your organizational structure and the requirements profile for employees?

Carl Mrusek: Exactly, that is the advantage that family businesses have over large corporations: We can make decisions quickly and react on a daily basis if necessary. Hierarchies are flat and coordination processes are short. An exciting suggestion doesn't have to be prepared by agencies and coordinated across several levels before it is approved by the management and can be implemented. The go-ahead can also come immediately over lunch: "Great idea, we'll do it." In a corporate group, this fails because only very few employees have the opportunity to have lunch with the management. - And we only talk about business in exceptional cases. Most of the time, the break is about family, the weather, sports and leisure plans - lunch topics, in other words. - We need responsible team players who are willing to make a change. People who work with others on an equal footing, who are committed to the company and its goals with drive and expertise and who are keen to try new things.

 

It now takes much more than a fruit basket and a gym to motivate current and potential employees. Working in a meaningful way and participating in a climate-friendly transformation is particularly important to many people. What does JUMBO-Textil do specifically to not just quote SDGs in a statement, but to live them in everyday company life?

Carl Mrusek: We have set ourselves a specific climate target: By 2035, our administrative and production operations at our headquarters will be climate-neutral. Realistic steps have been defined to achieve this. We have already achieved an important interim goal: at our headquarters in Sprockhövel, we only use green electricity from the sun, wind and water. We offset the unavoidable emissions for our heat generation with CO₂ compensation services. We are also developing more and more products from recyclable and recycled materials. Our vehicle fleet is currently being converted to purely electric or hybrid models.

 

Diversification and internationalization are part of every corporate strategy these days. But what do these terms mean for the management style of a medium-sized company in Sprockhövel? Do you consciously build interdisciplinary international teams?

Carl Mrusek: We live in a hyper-diverse society. This is also reflected in our company. Our teams consist of people with different international backgrounds, without us having to actively control this. The age structure is now also very mixed. We see the different perspectives as an asset, an opportunity and a success factor. We - and that ultimately means our customers and their projects - benefit from the variety of perspectives that flow into our solutions. As with many companies in the technical textiles sector, the proportion of women in some teams is still somewhat unbalanced. However, it is fortunately increasing steadily.

 

Generational change and succession planning are core issues for family-run companies. How important is it for JUMBO-Textil to professionalize its management team and to what extent is the company open to external specialists and managers?

Carl Mrusek: A company that closes its doors to external specialists and managers is also closing a door to success. That would be foolish. At JUMBO-Textil, we try to combine and balance the close ties, personal continuity and flexibility of a family-run company, the passion and innovative spirit of a start-up and the solidity and financial strength of a group. With Patrick Kielholz as COO, the next generation of the family is represented at management level, as is the external view and the diversity of perspectives provided by the other new members at C-level. The Textation Group, which also includes Patrick Kielholz's brother Kevin Kielholz, supports the company and enables it to think and act bigger than medium-sized family businesses often do. JUMBO-Textil is an elastic specialist. And what distinguishes our product also distinguishes us as an organization. We span the advantages of a family business as well as those of a start-up and a group. If I may use the image of elasticity here and not stretch it too far. (laughs)

Tufts researchers harness protein from silk to make virus-sensing gloves, surgical screws that dissolve in your body, and other next-generation biomedical materials

About a mile northwest of Tufts’ Medford/Somerville campus, on the fourth floor of a refurbished woolen factory, there is a shrine to silk. Glass vases filled with silkworm cocoons and washed silk fibers sit artfully on a shelf across from a colorful drawing of the life cycle of Bombyx mori, the domesticated silk moth. Farther in, more cocoons in wall-mounted cases border a large, close-up image of silk fibers, and displays hold dozens of prototypes made from silk, including smart fabrics, biosensors, a helmet that changes color upon impact, and potential replacements for materials like leather, plastic, and particle board.

The only things missing are the silkworms themselves, but Fiorenzo Omenetto, the director of Silklab and the Frank C. Doble Professor of Engineering at Tufts, said they will be arriving soon. The lab is building a terrarium so that visitors can view the animals.
“We’re going to have a celebration of silkworms and moths,” Omenetto said.

Silk has been cultivated and harvested for thousands of years. It is best known for the strong, shimmering fabric that can be woven from its fibers, but it also has a long history of use in medicine to dress injuries and suture wounds. At Silklab, Omenetto and his colleagues are building on silk’s legacy, proving that this ancient fiber could help create the next generation of biomedical materials.

Silk moth caterpillars, known as silkworms, extrude a single sticky strand of silk from their mouths to form cocoons, which are harvested by silk farmers to make silk thread. At its core, silk is a mixture of two proteins: fibroin, which provides the fiber’s structure, and sericin, which binds it together. With a few steps in the lab, Tufts researchers can remove the sericin and dissolve the fibers, turning a dry cocoon into a fibroin-filled liquid.

“Nature builds structural proteins that are very tough and very strong,” Omenetto said. “Your bricks are these fibroin proteins floating in water. From there, you can build whatever you want.”
Starting with shipments of dried cocoons from silk farms, Omenetto and his colleagues have been able to create gels, sponges, clear plastic-like sheets, printable inks, solids that look like amber, dippable coatings, and much more.

“Each of the materials that you make can contain all these different functions, and there’s only 24 hours in a day,” Omenetto said with a laugh. “This is why I don’t sleep.”

Biocompatible and Biodegradable
When Omenetto arrived at Tufts almost two decades ago, his research was focused on lasers and optics—silk wasn’t in the picture. But a chance conversation with David Kaplan, the Stern Family Professor of Engineering and chair of the biomedical engineering department, set him on a new path.

Kaplan, who has been working with silk since the early ’90s, was designing a silk scaffold that would help rebuild a person’s cornea, allowing cells to grow between the layers. He needed a way to ensure that the growing cells would have enough oxygen and showed the small, transparent sheet to Omenetto, who was immediately intrigued by the material. Omenetto was able to use his lab’s lasers to put tiny holes in Kaplan’s silk cornea. More collaborations quickly followed.
“We’ve worked together incessantly since then,” Kaplan said.

One of those lines of research has been finding ways to use silk to help repair and regrow bone, blood vessels, nerves, and other tissue. Silk is biocompatible, meaning it doesn’t cause harm in the body and breaks down in predictable ways. With the right preparation, silk materials can provide necessary strength and structure while the body is healing.

“You can mold and shape silk to whatever you need, and it will hold that volume while the native tissue regrows into the space and the silk material degrades,” Kaplan said. “Eventually it’s 100 percent gone, and you’re back to your normal tissue.”

Some of this work has already been approved for use by the U.S. Food and Drug Administration. A company called Sofregen, which spun out of Kaplan and Omenetto’s research, is using an injectable silk-based gel to repair damaged vocal cords, the tissues that regulate air flow and help us speak.

On their own, sturdy silk structures can keep their size, shape, and function for years before degrading. But in some instances, such as those involving surgical screws and plates intended for use in rapidly growing children, this pace would be too slow. The researchers had to find a way to speed up the time it takes for dense silk biomaterials to break down. They introduced an enzyme that our bodies produce naturally into the silk to hasten the breakdown process. The idea is that the enzyme would sit dry and inactive within the silk device until the structure is installed in a person, then the device would hydrate and activate the enzyme to digest the material more rapidly.

“We can titer in just the right amount of enzyme to make a screw go away in a week, a month, a year,” Kaplan said. “We have control over the process.”

Currently, Kaplan and his lab are working on other small, degradable medical devices that would help cut down on the number of surgeries that patients need. Ear tubes, for example, are often surgically implanted to help alleviate chronic ear infections and then need to be surgically removed. Kaplan and his colleagues have designed silk-based ear tubes that degrade on their own and can even carry antibiotics.

“As someone with a daughter who went through six surgeries on her ear, I know how helpful this could be,” Kaplan said.

The search for better, planet-friendly footwear material reveals a solution in one unlikely ingredient: pineapple leaves. This unique textile ingredient is the recent focus of the latest footwear design collaboration between Ananas Anam, TENCEL™ and Calvin Klein, launching Calvin Klein’s first-ever trainer featuring a knitted upper made of PIÑAYARN® blended with TENCEL™ Lyocell fibers.

Known as “The Sustainable Knit Trainer”, the trainers are a timeless closet staple, available in classic colors such as black and off-white and etched with the signature Calvin Klein logo. The PIÑAYARN® knit upper, made of 70% TENCEL™ Lyocell and 30% Anam PALF™ pineapple leaf fiber, is both from botanic origin and bio-based.

As the fashion sector has begun to realize the negative environmental effects of synthetic materials, a lot of brands have turned towards plant-based materials such as PIÑAYARN®. Using a low-impact manufacturing process, PIÑAYARN® is derived from pineapple leaf waste and involves a water-free spinning process. The addition of TENCEL™ Lyocell, a fiber made from wood pulp obtained from responsibly managed forests and produced using a solvent spinning process that recycles both the solvent and water at a recovery rate of more than 99%, offers full traceability of the TENCEL™ fiber in the final blended yarn.

Melissa Braithwaite, PIÑAYARN® Product Development Manager at Ananas Anam said “The inspiration for PIÑAYARN® came from the need to provide the textile industry with an alternative to overused, often polluting, conventional fibers, such as cotton or polyester. We have an abundance of available raw material within our business, and broadening our product offering means we can valorize more waste, increasing our positive impact on the environment and society.”

Indeed, as the consumer demand for more eco-responsible textile products and footwear grows, so too has the popularity of wood-based fibers as a material alternative. Ananas Anam and TENCEL™’s collaboration with Calvin Klein has been a success in that the physical characteristics and planet-conscious benefits of both PIÑAYARN® and TENCEL™ fibers complement each other perfectly, creating a blended material that is soft and usable for various woven and knitted applications.

For material developers like Ananas Anam seeking the ideal fiber blend partner to create PIÑAYARN®, TENCEL™ Lyocellfibers are celebrated for their versatility and ability to be blended with a wide range of textiles such as hemp, linen and of course Anam PALF™ pineapple leaf fiber, to enhance the aesthetics, performance and functionality of fabrics. Additionally, beyond being used in shoe uppers, TENCEL™ Lyocell fibers can be used in every part of the shoe including the upper fabric, lining, insoles, padding, laces, zipper and sewing thread. TENCEL™ Lyocell can also be used in powder form for use in the outsoles of shoes.

“We are extremely excited about this collaboration with Ananas Anam for the launch of The Sustainable Knit Trainer by Calvin Klein, an eco-responsible and planet-friendly shoe for conscious consumers. This partnership is the perfect example of our commitment to provide education and expertise to support anyone who chooses to improve the environmental and social credentials of their products by using more responsible materials,” said Nicole Schram, Global Business Development Manager at Lenzing.

During pregnancy, regular medical check-ups provide information about the health and development of the pregnant person and the child. However, these examinations only provide snapshots of their state, which can be dangerous, especially in high-risk cases. To enable convenient and continuous monitoring during this sensitive phase, an international research consortium is planning to further develop the technology of smart textiles. A patch equipped with highly sensitive electronics is meant to collect and evaluate vital data. In addition, the sensors will be integrated into baby clothing in order to improve the future of medical monitoring for newborns with the highest level of data security.

The beginning of a pregnancy is accompanied by a period of intensive health monitoring of the baby and the pregnant person. Conventional prenatal examinations with ultrasound devices, however, only capture snapshots of the respective condition and require frequent visits to doctors, especially in high-risk pregnancies. With the help of novel wearables and smart textiles, researchers in the EU-funded project Newlife aim to enable continuous obstetric monitoring in everyday life.

One goal of the consortium, consisting of 25 partners, is the development of a biocompatible, stretchable, and flexible patch to monitor the progress of the pregnancy and the embryo. Similar to a band-aid, the patch will be applied to the pregnant person’s skin, continuously recording vital data using miniaturized sensors (e.g., ultrasound) and transmitting it via Bluetooth.

For some time now, modern medical technology has been relying on smart textiles and intelligent wearables to offer patients convenient, continuous monitoring at home instead of stationary surveillance. At the Fraunhofer Institute for Reliability and Microelectronics IZM, a team led by Christine Kallmayer is bringing this technology to application-oriented implementation, benefitting from the Fraunhofer IZM’s years of experience with integrating technologies into flexible materials. For the integrated patch, the researchers are using thermoplastic polyurethane as base materials, in which electronics and sensors are embedded. This ensures that the wearing experience is similar to that of a regular band-aid instead of a rigid film.

To ensure that the obstetric monitoring is imperceptible and comfortable for both pregnant individuals and the unborn child, the project consortium plans to integrate innovative MEMS-based ultrasound sensors directly into the PU material. The miniaturized sensors are meant to record data through direct skin contact. Stretchable conductors made of TPU material tracks will then transmit the information to the electronic evaluation unit and finally to a wireless interface, allowing doctors and midwives to view all relevant data in an app. In addition to ultrasound, the researchers are planning to integrate additional sensors such as microphones, temperature sensors, and electrodes.

Even after birth, the new integration technology can be of great benefit to medical technology: With further demonstrators, the Newlife team plans to enable the monitoring of newborns. Sensors for continuous ECG, respiration monitoring, and infrared spectroscopy to observe brain activity will be integrated into the soft textile of a baby bodysuit and a cap. "Especially for premature infants and newborns with health risks, remote monitoring is a useful alternative to hospitalization and wired monitoring. For this purpose, we must guarantee an unprecedented level of comfort provided by the ultra-thin smart textiles: no electronics should be noticeable. Additionally, the entire module has to be extremely reliable, as the smart textiles should easily withstand washing cycles," explains Christine Kallmayer, project manager at Fraunhofer IZM.

For external monitoring of the baby's well-being, the project is also researching ways to use camera data and sensor technology in the baby's bed. Once the hardware basis of the patch, the textile electronics, and the sensor bed is built and tested, the project partners will take another step forward. Through cloud-based solutions, AI and machine learning will be used to simplify the implementation for medical staff and ensure the highest level of data security.

The Newlife project is coordinated by Philips Electronics Nederland B.V. and will run until the end of 2025. It is funded by the European Union under the Horizon Europe program as part of Key Digital Technologies Joint Undertaking under grant number 101095792 with a total of 18.7 million euros.

Interview on the trade fair landscape for floor coverings in Germany

The effects of the Corona pandemic were felt in almost all areas of social and economic life. The trade fair industry in particular was severely affected, with many events cancelled or postponed. With the return to normality, the question arises as to what significance leading trade fairs will have in the post-Corona era and how the competition between different organisers will develop. For its KLARTEXT interview series, Textination talked to Ms Sonia Wedell-Castellano, Global Director of DOMOTEX Events.

 

After DOMOTEX was unable to take place in 2021 and 2022 due to the pandemic, the trade fair returned in 2023 with a successful event. Nevertheless, the number of exhibitors has almost halved compared to 2020. How do you assess the future importance of leading trade fairs after the industry had to come to terms with online meetings and travel restrictions for a long period of time?

I think it is important to remember that this was the first DOMOTEX since the outbreak of the pandemic, and at a time when the global economic situation is rather difficult. Of course, this situation has made some companies reluctant to participate in DOMOTEX 2023, so we have not yet been able to welcome all companies back as exhibitors at the show. In addition, there were still significant travel restrictions in place at the beginning of the year, for example in China, which simply made it more difficult for our exhibitors to participate in a trade fair abroad. As far as our expectations for the next event are concerned, I can say that many companies - even those that did not exhibit this year - have communicated their interest in wanting to be back at DOMOTEX 2024.
 
We are certain that leading trade fairs and exhibitions in general will continue to be of great importance in the future! You may be able to cultivate existing customers at digital events, but you can't generate new ones. The focus of DOMOTEX is on products you can touch, on the haptic experience on site. You can't transfer that to the digital world. Even the chance encounters at the stand or in the halls do not happen digitally. But a trade fair thrives on personal encounters, personal exchanges. Business is done between people, not between screens. Both exhibitors and visitors have told us quite clearly that they want and need DOMOTEX to be a trade fair where people are present.

 

The degree of internationalisation among DOMOTEX visitors was between 62 and 67 percent in the last three years of the event before the pandemic; in 2023 it even reached 69 percent. Would you agree that leading international trade fairs in Germany are now primarily only important for export-oriented companies? And what does that imply for the economic efficiency of trade fairs?

Certainly, leading international trade fairs in Germany are particularly interesting for export-oriented companies, but not exclusively. That doesn't change anything at all about the profitability of trade fairs. We generate our turnover with all our exhibitors, regardless of whether they are export-oriented or only interested in the Germany-Austria-Switzerland region. That's why satisfied exhibitors are very important to us. And an exhibitor is satisfied when he can do good business or make good contacts at our fairs. It's more and more about the right quality of visitors, less about the quantity. In any case, all our exhibitors very much welcome international visitors!

 

For the 2024 edition, Deutsche Messe has announced that its DOMOTEX concept has been changed to focus on different areas each year: Carpet & Rugs in the odd-numbered years and Flooring in the even-numbered years. Flooring covers wood and laminate flooring, parquet, design flooring, resilient floor coverings, carpets, outdoor flooring and application and installation technology. Carpet & Rugs stands for hand-made carpets and runners as well as for machine-woven carpets.

Yet you say that the Carpet & Rugs segment in particular needs an annual presentation platform, while the flooring segment would like to see DOMOTEX every two years as the central platform for the industry due to longer innovation cycles. Doesn't that actually mean that floor coverings are only in Hannover every other year, but carpets continue to exhibit annually in Hannover? Could you clarify that?

DOMOTEX - Home of Flooring will take place in 2024 and in all even years: This is a DOMOTEX with all exhibitors as we know them from the past. So, from herringbone parquet to outdoor coverings, oriental carpets and contemporary designs - everything, under one roof. In the odd years, i.e. from 2025, there will then be DOMOTEX - Home of Carpets and Rugs, with a focus on suppliers of fitted carpets. The background to this is that the hard flooring industry had wanted DOMOTEX to be held every two years. After this year's DOMOTEX, the suppliers of wall-to-wall carpets have again clearly spoken out in favour of an annual platform. With our new focus model, we are meeting the needs that the market has expressed to us.

 

Messe Frankfurt has declared a new product segment for next year's Heimtextil - interestingly, under the name Carpets & Rugs. While the watchword at DOMOTEX in the even year 2024 is Flooring, Heimtextil offers an alternative trade fair venue for carpets. How do you assess this situation - do exhibitors now have to choose between Hannover and Frankfurt and what does this mean for the split concept?

No, exhibitors from the carpet sector will not have to choose between Hannover and Frankfurt in future - because DOMOTEX is and will remain the home of the entire industry, even in the even years! At DOMOTEX, Home of Flooring means, as I explained earlier, that we present the entire spectrum of floor coverings and carpets. But what is even more important is that we have been told by exhibitors and many visitors that the market does not want to be split up any further. Through the many (small) events, the flooring industry is only competing with itself. To put it bluntly: if only some of the exhibitors take part in ten events, it can't really work. The critical mass is missing. A trade fair is only as good as its participants and they often don't have the time to visit several events.    

 

Another innovation for DOMOTEX is the country focus. What do you expect from this and why did you choose "Insight Italy" for 2024?

With our new special presentation, we want to arouse the curiosity of our visitors - especially retailers, architects and contractors - and highlight the international character of DOMOTEX. After all, what could be more exciting than getting to know a country in depth?  

That is why the INSIGHT concept will in future feature a different country at each DOMOTEX - Home of Flooring. Special exhibition areas will showcase innovations and products, present partnerships with designers and universities, and stage trends. In addition, the conference will provide insights into the respective market and references.  
In 2024, we will start with Italy, a very design-savvy and creative country from which many trends come.

 

Deutsche Messe wants to strengthen the Hannover venue for the leading trade fair DOMOTEX and to hold additional fairs only in Shanghai and in Gaziantep. There will be no Carpet Expo in Istanbul. What influence does the changing entrepreneurial landscape in terms of production countries and markets have on your international concept?

First of all, it must be noted that the business landscape for carpets has not changed in Turkey. Here, only the associations have decided to organise a carpet fair in Istanbul in the future. The background is the continuing visa problem for Turkish exhibitors in Germany as well as the immensely high inflation in Turkey, which makes foreign participation extremely costly for Turkish companies. We would have liked to organise a carpet fair in Istanbul together with the Turkish associations, but not at any price and not on their terms alone. Hannover is and will remain the international platform for DOMOTEX, and we will continue to strengthen this location.

But of course, we also keep an eye on the global market and keep our eyes and ears open at all times, for all our brands, by the way. It was only in this way that DOMOTEX asia/Chinafloor in Shanghai was able to develop into what is now a very successful event. The potential was there, we were in the right place at the right time. If we hadn't seized the opportunity at the time, there would still be a strong floor coverings trade fair in Shanghai - but it would be run by one of our competitors and it wouldn't be called DOMOTEX today.

Many thanks to Ms Sonia Wedell-Castellano for the KLARTEXT.
