How can the major sustainability challenges in the textile industry be met? The textile services industry, whose business model has always been based on durability and re-use, has an important role to play here as ambassador. In the run-up to Texcare International, Elena Lai, Secretary General European Textile Services Association (ETSA), talks about these challenges and her expectations for Texcare International from 27 November to 1 December 2021.

The textile sector was identified as a priority sector in the European Green Deal and in the Circular Economy Action Plan. What are the implications for the European textile services industry?
Elena Lai: We are in a truly historic and exciting time for the textile services industry. We are all well-aware that our industry is the key to providing sustainable solutions and ecofriendly best practice. We had a series of webinars at ETSA dedicated to sustainability and circular economy being key elements of the Green Deal and our larger companies such as industrial laundries, key textile manufacturers and innovative machinery companies, are all up to the task and providing effective solutions. Our national associations too, members of ETSA, are all working synergistically to exchange their best ways forward, in Europe and beyond as we have also partners from the US. These efforts within ETSA’s value chain make us really proud and eager to go the extra mile, guiding our members also towards those areas which seem to be the most challenging. For instance, the new EU Climate Law, which calls for 55% CO₂ reductions by 2030: this means that European industries will all have to do better to make us reach these targets in less than nine years. We know ETSA could represent the right network to identify the best way forward on this issue and truly perform and deliver what the EU is advocating for.

How can the textile services industry contribute to achieving circular economy in the textile industry?
Elena Lai: The business model of textile services is inherently circular. By having a business model which is focused on renting and reusing textiles we can see a litany of benefits that it can offer to the EU’s Circular Economy Action Plan. Firstly, in renting textiles. Through rented textile services, textile service companies can extend the lifecycle of products and thus reduce the amount of production that is necessary to occur in the first place, while also reducing the amount of wastewater and energy needed in the laundry process. Secondly, through re-use and repair textile products can remain in consumer hands for longer, which is paramount as our industry is one that battles against planned obsolescence. Both of these are important pillars to our industries that will help both consumers and the planet. Lastly, by continuing to expand recycling and upcycling we can minimise waste, ensuring that a product stays inside the European economy as long as possible. These are all important steps and help us do our part to help Europe reach its emissions and sustainability goals.

Textile recycling is a very important point. How do you think the textile recycling rate can be increased?
Elena Lai: The Commission will mandate separate waste sorting of textiles by the year 2025, thus recycling, upcycling and end of life re-use must be improved. A ban on the burning of unused textiles will also soon take effect, this will incentivise further recycling and waste reduction. Fundamentally what we in textiles services need to do is to continue to reduce, re-use and recycle. We can increase the rate of recycling by making consumers aware of rented textiles and textile services so to increase the public demand for such services.

How can sustainability in textile services be further improved?
Elena Lai: In order to boost sustainability in our industry we need to build on the existing culture of innovation and entrepreneurship where exciting, new, out-of-the-box ideas can be developed and refined. EU programs like Horizon Europe, which emphasise green and digital solutions to common problems are an excellent way to empower citizens, textile service firms and local communities to take the initiative and take matters into their own hands. The EU’s Due Diligence legislation is one example of somewhere we can see both consumers and firms come together and take proactive action to improve sustainability, not only in textiles and textile services, but in European industry more broadly. To put it clearly, we have to strengthen our technological innovation while also empowering consumers, authorities and textile service firms, we believe our work at the EU level helps to make this a reality.

How does ETSA promote new projects in the field of sustainability?
Elena Lai: We at ETSA have been hard at work lobbying EU policymakers for responsible legislation, while also spreading awareness of the industry’s best practice to the public. Recently ETSA has also become an EU Commission Climate Pact Ambassador. This is an exciting opportunity which will allow ETSA to work closely with European Institutions to inform and inspire real climate action amongst our members, national associations and the industry as a whole. ETSA is a platform where stakeholders, citizens, industries and European Union representatives can come together and have a dialogue on the best ways to improve Europe’s sustainability. Furthermore, we have been hard at work disseminating information on the best practice that will help Europe get to 55% emissions reductions, as well information on chemicals, waste-water, microplastics and other salient environmental issues. Our work is far from being done but we look forward to continuing to strive and advance via our focused Working Group on Environment and our webinars to make the world green and sustainable again.

What role will circular economy/sustainability play at Texcare?
Elena Lai: A central role, several European and World Leaders have underlined, is that Climate Change is the most important issue of our time and it is imperative we act now. Climate Change is also an issue with a global spill over and therefore we all have a clear incentive to find solutions and work in synergy with each other. We need future-oriented dialogue which understands the urgent need for sustainability across the entire textile value chain. ETSA in synergy with one of our members, DTV, is working hard to put together a panel at Texcare dedicated to the sustainability debate, with lots of members and participants to get engaged.

What does ETSA expect from this year's Texcare?
Elena Lai: We at ETSA are excited to be at Texcare, we think it’s a great opportunity to not only network and converse with other relevant actors in the industry but also to share best practice, concerns and most of all opportunities. Due to the pandemic we had a difficult year 2021 and this event will really enhance a stronger engagement of key actors in this sector. The need for green, sustainable and digital solutions is nonetheless imperative. We are looking forward to hearing of ways that the industry across the world not only continues to adapt to the evolving COVID situation, but also how it is embracing the green and digital transition that has been emphasised as being the futuristic approach by our EU policymakers. We at ETSA wholeheartedly look forward to this event.

Texcare International will take place from November 27 December 1, 2021 in Frankfurt am Main.

Stand-up paddling has become a popular sport. However, conventional surfboards are made of petroleum-based materials such as epoxy resin and polyurethane.

Researchers at the Fraunhofer Institute for Wood Research, Wilhelm-Klauditz-Institut, WKI, want to replace plastic boards with sustainable sports equipment: They are developing a stand-up paddle board that is made from one hundred percent renewable raw materials. The ecological lightweight material can be used in many ways, such as in the construction of buildings, cars and ships.

Stand-up paddling (SUP) is a sport that is close to nature, but the plastic boards are anything but environmentally friendly. As a rule, petroleum-based materials such as epoxy resin, polyester resin, polyurethane and expanded or extruded polystyrene are used in combination with fiberglass and carbon fiber fabrics to produce the sports equipment. In many parts of the world, these plastics are not recycled, let alone disposed of correctly. Large quantities of plastic end up in the sea and collect in huge ocean eddies. For Christoph Pöhler, a scientist at Fraunhofer WKI and an avid stand-up paddler, this prompted him to think about a sustainable alternative. In the ecoSUP project, he is driving the development of a stand-up paddle board that is made from 100 percent renewable raw materials and which is also particularly strong and durable. The project is funded by the German Federal Ministry of Education and Research (BMBF). The Fraunhofer Center for International Management and Knowledge Economy IMW is accompanying the research work, with TU Braunschweig acting as project partner.

Recovering balsa wood from rotor blades
“In standard boards, a polystyrene core, which we know as styrofoam, is reinforced with fiberglass and sealed with an epoxy resin. We, instead, use bio-based lightweight material,” says the civil engineer. Pöhler and his colleagues use recycled balsa wood for the core. This has a very low density, i.e. it is light yet mechanically stressable. Balsa wood grows mainly in Papua New Guinea and Ecuador, where it has been used in large quantities in wind turbines for many years – up to six cubic meters of the material can be found in a rotor blade. Many of the systems are currently being disconnected from the grid. In 2020 alone, 6000 were dismantled. A large proportion of this is burnt. It would make more sense to recover the material from the rotor blade and recycle it in accordance with the circular economy. “This was exactly our thinking. The valuable wood is too good to burn,” says Pöhler.

Since the entire sandwich material used in conventional boards is to be completely replaced, the shell of the ecological board is also made from one hundred percent bio-based polymer. It is reinforced with flax fibers grown in Europe, which are characterized by very good mechanical properties. To pull the shell over the balsa wood core, Pöhler and his team use the hand lay-up and vacuum infusion processes. Feasibility studies are still underway to determine the optimal method. The first demonstrator of the ecological board should be available by the end of 2022. “In the interests of environmental protection and resource conservation, we want to use natural fibers and bio-based polymers wherever it is technically possible. In many places, GFRP is used even though a bio-based counterpart could do the same,” Pöhler sums up.

Patented technology for the production of wood foam
But how is it possible to recover the balsa wood from the rotor blade — after all, it is firmly bonded to the glass-fiber reinforced plastic (GFRP) of the outer shell? First, the wood is separated from the composite material in an impact mill. The density differences can be used to split the mixed-material structures into their individual components using a wind sifter. The balsa wood fibers, which are available as chips and fragments, are then finely ground. “We need this very fine starting material to produce wood foam. Fraunhofer WKI has a patented technology for this,” explains the researcher. In this process, the wood particles are suspended to form a kind of cake batter and processed into a light yet firm wood foam that holds together thanks to the wood’s own binding forces. The addition of adhesive is not required. The density and strength of the foam can be adjusted. “This is important because the density should not be too high. Otherwise, the stand-up paddle board would be too heavy to transport.”

Initially, the researchers are focusing on stand-up paddle boards. However, the hybrid material is also suitable for all other boards, such as skateboards. The future range of applications is broad: For example, it could be used as a facade element in the thermal insulation of buildings. The technology can also be used in the construction of vehicles, ships and trains.

• Circular economy for plastics: Fraunhofer, SABIC, and Procter & Gamble join forces

The Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE and its Institute for Environmental, Safety and Energy Technology UMSICHT have developed an advanced recycling process for used plastics. The pilot project with SABIC and Procter & Gamble serves to demonstrate the feasibility of closed-loop recycling for single-use facemasks.

The transformation from a linear to a circular plastics economy can only succeed with a multi-stakeholder approach. The Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE combines the competencies of six institutes of the Fraunhofer-Gesellschaft and cooperates closely with partners from industry. Together, we work on systemic, technical and social innovations and keep an eye on the entire life cycle of plastic products.  

Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT is a pioneer in sustainable energy and raw materials management by supplying and transferring scientific results into companies, society and politics. Together with partners, the dedicated UMSICHT team researches and develops sustainable products, processes and services which inspire.

Fraunhofer Institute UMSICHT, SABIC and Procter & Gamble (P&G) are collaborating in an innovative circular economy pilot project which aimed to demonstrate the feasibility of closed-loop recycling of single-use facemasks.

Due to COVID-19, use of billions of disposable facemasks is raising environmental concerns especially when they are thoughtlessly discarded in public spaces, including - parks, open-air venues and beaches. Apart from the challenge of dealing with such huge volumes of essential personal healthcare items in a sustainable way, simply throwing the used masks away for disposal on landfill sites or in incineration plants represents a loss of valuable feedstock for new material.

“Recognizing the challenge, we set out to explore how used facemasks could potentially be returned into the value chain of new facemask production,” says Dr. Peter Dziezok, Director R&D Open Innovation at P&G. “But creating a true circular solution from both a sustainable and an economically feasible perspective takes partners. Therefore, we teamed up with Fraunhofer CCPE and Fraunhofer UMSICHT’s expert scientists and SABIC’s T&I specialists to investigate potential solutions.”

As part of the pilot, P&G collected used facemasks worn by employees or given to visitors at its manufacturing and research sites in Germany. Although those masks are always disposed of responsibly, there was no ideal route in place to recycle them efficiently. To help demonstrate a potential step change in this scenario, special collection bins were set up, and the collected used masks were sent to Fraunhofer for further processing in a dedicated research pyrolysis plant.

“A single-use medical product such as a face mask has high hygiene requirements, both in terms of disposal and production. Mechanical recycling, would have not done the job” explains Dr. Alexander Hofmann, Head of Department Recycling Management at Fraunhofer UMSICHT. “In our solution, therefore, the masks were first automatically shredded and then thermochemically converted to pyrolysis oil.

Pyrolysis breaks the plastic down into molecular fragments under pressure and heat, which will also destroy any residual pollutants or pathogens, such as the Coronavirus. In this way it is possible to produce feedstock for new plastics in virgin quality that can also meet the requirements for medical products” adds Hofmann, who is also Head of Research Department “Advanced Recycling” at Fraunhofer CCPE.

The pyrolysis oil was then sent to SABIC to be used as feedstock for the production of new PP resin. The resins were produced using the widely recognized principle of mass balance to combine the alternative feedstock with fossil-based feedstock in the production process. Mass balance is considered a crucial bridge between today’s linear economy and the more sustainable circular economy of the future.

“The high-quality circular PP polymer obtained in this pilot clearly demonstrates that closed-loop recycling is achievable through active collaboration of players from across the value chain,” emphasizes Mark Vester, Global Circular Economy Leader at SABIC. “The circular material is part of our TRUCIRCLE™ portfolio, aimed at preventing valuable used plastic from becoming waste and at mitigating the depletion of fossil resources.”

Finally, to close the loop, the PP polymer was supplied to P&G, where it was processed into non-woven fibers material. “This pilot project has helped us to assess if the close loop approach could work for hygienic and medical grade plastics.” says Hansjörg Reick, P&G Senior Director Open Innovation. “Of course, further work is needed but the results so far have been very encouraging”.

The entire closed loop pilot project from facemask collection to production was developed and implemented within only seven months. The transferability of advanced recycling to other feedstocks and chemical products is being further researched at Fraunhofer CCPE.

"Packaging made from bio-based plastics has long been established. We are now supporting the further development of these materials for new areas of application. If in the future the market also offers plant-based materials for technically demanding tasks such as vehicle construction, the bioeconomy will take a decisive step forward," explained Uwe Feiler, Parliamentary State Secretary at the Federal Ministry of Food and Agriculture, in Potsdam. The occasion was the handover of a grant to the Fraunhofer Institute for Applied Polymer Research IAP. The Fraunhofer IAP wants to develop a composite material that consists entirely of bio-based polylactic acid (PLA) and is significantly easier to recycle than conventional fiber composites.

The German Federal Ministry of Food and Agriculture (BMEL) is intensively promoting the development of biomaterials as part of its Renewable Resources funding program. More than 100 projects are currently underway, covering a wide range of topics: from plastics that are degradable in the sea to natural fiber-reinforced lightweight components for the automotive sector. The projects are supported by the Agency for Renewable Resources, the BMEL project management agency responsible for the Renewable Resources funding program.

Easier recycling of fiber-reinforced plastics
PLA is one of the particularly promising bio-based materials. The global market for this polymer is growing by around 10 percent a year. PLA is also used, among other things, as a matrix in fiber-reinforced plastics. In these mechanically resilient plastics, reinforcing fibers are embedded in a plastic matrix.

The Fraunhofer IAP project is now focusing on these reinforcing fibers: "We are further developing our PLA fibers in order to transfer them to industrial scale together with partners from industry. These fibers are ideally suited for reinforcing PLA plastics. The resulting self-reinforcing single-component composite promises great recycling benefits. Since the fiber and the matrix of PLA are chemically identical, complex separation steps are not necessary," explains Dr. André Lehmann, expert for fiber technology at Fraunhofer IAP.

Novel PLA fibers and films are more thermally stable
The challenge with this approach is that conventional PLA has a relatively low temperature resistance. Technical fibers can be produced most economically using the melt spinning process. The Fraunhofer IAP team is now using more thermally stable stereocomplex PLA (sc-PLA) for the fibers. The term stereocomplex refers to a special crystal structure that the PLA molecules can form. Sc-PLA fibers have a melting point that is 40 - 50 °C higher and can therefore withstand the incorporation process in a matrix made of conventional PLA. In the project, the researchers are developing and optimizing a melt spinning process for sc-PLA filament yarns. The partner in this work package is Trevira GmbH, a manufacturer of technical and textile fiber and filament yarn specialties that are in demand from automotive suppliers and contract furnishers, among others. Furthermore, the development of a manufacturing process for sc-PLA reinforced flat films is planned. The international adhesive tape manufacturer tesa SE is participating in this task, and will test the suitability of sc-PLA films as adhesive foils. In a third work package, the Fraunhofer IAP will finally process the filaments in a double pultrusion process to produce granules suitable for injection molding.

Bio-based solutions for the automotive and textile industries
The scientists led by Dr. André Lehmann are certain that the self-reinforced PLA material can conquer many new areas of application. The automotive and textile industries are already showing interest in bio-based materials that are also easier to recycle. In terms of price, PLA would already be competitive here, and now the material is also to be made technically fit for the new tasks.

Professor Alexander Böker, head of Fraunhofer IAP, says: "The steadily growing demand from industry for sustainable solutions underlines how important it is to develop biobased and at the same time high-performance materials. With our research, we are also actively driving the development of a sustainable and functioning circular economy and therefore very much welcome the support from the federal government."

• The “Bioconcept-Car” moves ahead

In automobile racing, lightweight bodies made from plastic and carbon fibers have been standard for many years because they enable drivers to reach the finish line more quickly. In the future, lightweight-construction solutions could help reduce the energy consumption and emissions of everyday vehicles. The catch is that the production of carbon fibers is not only expensive but also consumes considerable amounts of energy and petroleum. In collaboration with Porsche Motorsport and Four Motors, researchers at the Fraunhofer WKI have succeeded in replacing the carbon fibers in a car door with natural fibers. This is already being installed in small series at Porsche. The project team is now taking the next step: Together with HOBUM Oleochemicals, they want to maximize the proportion of renewable raw materials in the door and other body parts - using bio-based plastics and paints.

Carbon fibers reinforce plastics and therefore provide lightweight components with the necessary stability. Mass-produced natural fibers are not only more cost-effective but can also be produced in a considerably more sustainable manner. For the “Bioconcept-Car” pilot vehicle, researchers at the Fraunhofer WKI have developed body parts with 100 percent natural fibers as reinforcing components.

“We utilize natural fibers, such as those made from hemp, flax or jute. Whilst natural fibers exhibit lower stiffnesses and strengths compared to carbon fibers, the values achieved are nonetheless sufficient for many applications,” explained Ole Hansen, Project Manager at the Fraunhofer WKI. Due to their naturally grown structure, natural fibers dampen sound and vibrations more effectively. Their lesser tendency to splinter can help to reduce the risk of injury in the event of an accident. Furthermore, they do not cause skin irritation during processing.

The bio-based composites were successfully tested by the Four Motors racing team in the “Bioconcept-Car” on the racetrack under extreme conditions. Porsche has actually been using natural fiber-reinforced plastics in a small series of the Cayman GT4 Clubsport since 2019. During production, the researchers at the Fraunhofer WKI also conducted an initial ecological assessment based on material and energy data. “We were able to determine that the utilized natural-fiber fabric has a better environmental profile in its production, including the upstream chains, than the fabric made from carbon. Thermal recycling after the end of its service life should also be possible without any problems,” confirmed Ole Hansen.

In the next project phase of the "Bioconcept-Car", the researchers at the Fraunhofer WKI, in collaboration with the cooperation partners HOBUM Oleochemicals GmbH, Porsche Motorsport and Four Motors, will develop a vehicle door with a biogenic content of 85 percent in the overall composite consisting of fibers and resin. They intend to achieve this by, amongst other things, utilizing bio-based resin-hardener blends as well as bio-based paint systems. The practicality of the door - and possibly additional components - will again be tested by Four Motors on the racetrack. If the researchers are successful, it may be possible to transfer the acquired knowledge into series production at Porsche.

The German Federal Ministry of Food and Agriculture (BMEL) is funding the “Bioconcept-Car” project via the project-management agency Fachagentur Nachwachsende Rohstoffe e. V. (FNR).

Background
Sustainability through the utilization of renewable raw materials has formed the focus at the Fraunhofer WKI for more than 70 years. The institute, with locations in Braunschweig, Hanover and Wolfsburg, specializes in process engineering, natural-fiber composites, surface technology, wood and emission protection, quality assurance of wood products, material and product testing, recycling procedures and the utilization of organic building materials and wood in construction. Virtually all the procedures and materials resulting from the research activities are applied industrially.

• EU Project ALMA: Thinking Ahead to Electromobility

E-mobility and lightweight construction are two crucial building blocks of modern vehicle development to drive the energy transition. They are the focus of the ALMA project (Advanced Light Materials and Processes for the Eco-Design of Electric Vehicles). Nine European organizations are now working in the EU project to develop more energy-efficient and sustainable vehicles. Companies from research and industry are optimizing the efficiency and range of electric vehicles, among other things by reducing the weight of the overall vehicle. The Fraunhofer Institute for Industrial Mathematics ITWM is providing support with mathematical simulation expertise.

According to the low emissions mobility strategy, the European Union aims to have at least 30 million zero-emission vehicles on its roads by 2030. Measures to support jobs, growth, investment, and innovation are taken to tackle emissions from the transport sector. To make transport more climate-friendly, EU measures are being taken to promote jobs, investment and innovation. The European Commission's Horizon 2020 project ALMA represents one of these measures.

As a result of the Corona pandemic, the PERFORMANCE DAYS fair on December 9^th - 10^th and the accompanying sustain&innovate conference for sustainability on December 10 could only take place in digital form. Nevertheless: exhibitors, visitors and partners can look back on a successful event. The focus topic “Nothing to Waste – Closing the Loop“ relating to the issue of the textile circular economy in the course of the sustain&innovate conference also provided great discussion material while generating a positive response.

The PERFORMANCE DAYS team also expresses its satisfaction. Because despite the event being solely a digital event on the 9^th and 10^th of December 2020, an estimated 15,000 participants made extensive use of the comprehensive online offerings of the 191 digital exhibitors, among them drirelease/OPTIMER, Merryson, Stotz, HeiQ, Schoeller Textil, Long Advance, Dry-Tex, Utenos, Fidlock, Cifra, dekoGraphics and Jia Meir, during the week of the fair. The popular “Contact Supplier” function was supplemented with a new online tool that allows exhibitors to be contacted directly via chat, call or per video. A total of 3,250 fabric sample orders were placed with exhibitors. The variety on offer included fabric innovations for Autumn/Winter 2022/2023 within the top class PERFORMANCE FORUM and an extensive digital supporting program via live-stream with informative webinars, talks and rounds of discussions. Best of all: the resulting videos will be available on demand on the PERFORMANCE DAYS website free of charge.  
 
Finally standard: PERFORMANCE FORUM with sustainable materials
Innovative, sustainable and cutting-edge: the 240 fabrics plus accessory trends at this year’s PERFORMANCE FORUM impressed throughout with exciting environmentally conscious solutions. Natural fibers such as hemp, organic cotton, bamboo, wool or coconut shell remain in demand, while manufacturers are also increasingly refraining from the use of environmentally harmful chemicals, avoiding microplastics, advocating natural dyeing processes and either trying to return fabrics to the cycle, recycle plastic and other waste in order to produce fibres in such a way that they are biodegradable. This environmental awareness is also reflected in this year’s FOCUS TOPIC – so here the 24 best fabrics not only score in terms of sustainability, but also demonstrate that they are both functional and can be returned to the textile cycle, true to the motto “Nothing to Waste – Closing the Loop.   

In the Marketplace section, visitors have the opportunity to view more than 9,500 exhibitor products, including the fabric highlights of the individual categories of the PERFORMANCE FORUMS. In order to be able to digitally present the fabrics to visitors as realistically as possible in terms of feel, design and structure, the Forum has been equipped with innovative 3D technology, including innovative tools such as 3D images, video animations and U3M files for download.  

From fiber to fiber: successful sustain&innovate conference generates discussion  
Textile circular economy is considered part of the solution to the global waste problem, curbing the consumption of resources and reducing climate damaging greenhouse gases. But what exactly is the circular economy and how can it succeed? Most importantly, how far are fiber manufacturers in developing mono-component fabrics that can eventually be returned back into the textile cycle?    
The Focus Topic of this year’s sustainability conference, launched in cooperation with SPORTSFASHION by SAZ, offered a platform for discussion and strove to enlighten with evocative talks, discussion rounds and webinars. Christiane Dolva, Head of Sustainability at Fjällräven, got to the heart of the matter at the start of the expert talks on the second day of the fair, outlining how important emotional consistency is for the brand itself and ultimately also for the consumer – especially when it comes to textile recycling. Durability, good quality, in combination with timeless design are more important than ever today and in the future in terms of sustainable action. Added to this is the possibility of reviving products by means of a repair service. Equally exciting: the development of new technologies in terms of recycling. Erik Bang from the H&M Foundation provided a first glimpse of the new Greenmachine, which should make it possible to separate mixed fabrics such as cotton and polyester as early as 2021. Alternatively, old clothing is converted into new fibres thanks to companies such as WornAgain, Re:newcell, Spinnova or Infinited Fiber, which soon promises to be more than just a mere vision. For those who wish to gain insight into the supply chain of their purchased garment, the start-up know your stuff lets customers track the journey of the respective garment by simply scanning a QR code on the garment in a store or online.    
 
Free extensive retrospective
The next edition of PERFORMANCE DAYS is planned as a hybrid fair and will take place on May 19^th and May 20^th, 2021 in Munich as well as online. Until then, the PERFORMANCE DAYS platform will remain accessible, for instance with the Marketplace and further inspiring topics of (video) material stories to make online sourcing even easier. The talks from the first day of the fair and the conference will be accessible free of charge on the fair website.

• Finite resources and endless mountains of rubbish set the tone of the upcoming 25th edition of PERFORMANCE DAYS. Closing the loop means nothing is wasted, not even time, as recycled clothing gets recycled again and again.

In keeping with this topic, the trade fair organizers are planning expert discussion panels to help present the facts as well as visions of the future. Expect the corresponding displays of sustainable materials, chosen by the PERFORMANCE FORUM Jury. Look for materials such as fibers from recycled PET bottles, recyclable mono-component materials or blends, and shirts that decompose to biomass in a "Cradle-to-Cradle" approach. "Nothing to Waste - Closing the Loop" is open to the public at the Messe München fairgrounds and as a Digital Fair online starting on December 9-10, 2020.

The PERFORMANCE DAYS trade fair has chosen a new Focus Topic that concerns not only our own industry. The textile industry has long been achieving more efficient production by recycling its own waste products and using recycled materials from outside the industry, for example, PET-bottles. Nevertheless, textiles exist alongside glass, paper, metal, and plastics as a separate branch of waste management. Despite ambitious efforts at recycling by the waste and textile industries, the efficient use of textile waste as a resource remains a challenge. Compounding this challenge are the difficulties caused by a global world: production, consumers, and disposal sites are miles apart, shared expert knowledge about the other industries is lacking, and international standards and political support are nearly non-existent.

Final destination: the waste bin
Information from the Federal Office for the Environment shows that 0.8% of the oil produced is used in the textile industry for the production of new textiles. But the costly processing chain of this finite resource ends all too quickly in waste. A Greenpeace survey reveals outdated fashions or clothing of worn quality is thrown away within three years, only to land in the trash dumpsters. The European Environmental Agency estimates that 5.8 million tons of used textiles are discarded every year and either incinerated, used for landfill, or taken to mechanical-biological sewage treatment plants. Even if used clothing is collected by state or private companies, in many cases it cannot be sold (as second hand), donated, or recycled (into rags or insulating material). In the best case scenario, it is incinerated and converted to thermal energy.

Recycling and circular design
From an economic and environmental perspective, the term recycling refers to waste-free products, waste avoidance, and waste recovery and disposal. In our industry as it stands, recycling at the end of the product life cycle usually means converting the product into some other product, i.e., not clothing. This is the "Open-Loop" process. Accordingly, textiles are eventually incinerated, but the amount of energy recovered can vary greatly depending on how efficiently the waste incineration plant works. Such devaluing of the product to a product with less value than the original product is known as Downcycling. However, Downcycling is not the only solution: the "Closed-Loop" approach has the goal of making new clothes out of old ones through recycling. The closed loop for renewable natural resources, for example, can mean that natural fibers used in textiles will end up becoming soil, which is the nutrient for new natural fibers, i.e., a cradle-to-cradle approach. Synthetic garments similarly require extracting the man-made fibers and reprocessing them to produce another garment.

Planning for the end in advance
Rather than thinking about recycling opportunities at the end of the product life cycle, brands can already begin developing closed loop options while in the design phase. Among other things, designing out the waste can reduce the environmental impact of the products. To extend the useful life, consider leasing the materials and/or adding labels with instructions for disposal, repair, or repurposing. And, what about the idea of preparing 100% used textiles that can be reintroduced into the supply chain as 100% new textiles? Separating the different types of fiber used in blends is complex, cost-intensive, and further complicated when labels are non-existent (or no longer existing) or it is simply not (yet) technically possible. More and more clothing makers and suppliers are trying to avoid mixing fibers and are switching to "mono-materials" or "mono-components." Shirts are easy to make in this way, but if you add buttons, zippers, etc., the issue becomes more complex.

•     09.-10. December 2020      DIGITAL FAIR  Trends Winter 2022/23 

UPDATE
CoVid-19 continues to keep the world on edge. Many PERFORMANCE DAYS visitors, as well as exhibitors, have already announced that travelling to Munich in December would be simply impossible for them. Due to the increasing number of infections, further international travel bans and company-internal travel restrictions are now threatening. As a result, the December 2020 edition of PERFORMANCE DAYS will unfortunately not take place at the Messe München, but as Digital Fair! On the planned dates of December 09-10, both approved and advanced new tools will go online and provide further proof of PERFORMANCE DAYS’ expansion of its pioneering role in creating a digital textile trade fair experience.

• Risk analyses for nanoparticles

In order to reduce the number of animal experiments in research, alternative methods are being sought. This is a particular challenge if the safety of substances that have hardly been studied is to be ensured, for instance, the completely new class of nanomaterials. To accomplish just that, Empa researchers are now combining test tube experiments with mathematical modelling.

They are already in use in, say, cosmetics and the textile industry: Nanoparticles in sun blockers protect us from sunburn, and clothing with silver nanoparticles slows down bacterial growth. But the use of these tiny ingredients is also linked to the responsibility of being able to exclude negative effects for health and the environment. Nanoparticles belong to the still poorly characterized class of nanomaterials, which are between one and 100 nanometers in size and have a wide range of applications, for example in exhaust gas catalytic converters, wall paints, plastics and in nanomedicine. As new and unusual as nanomaterials are, it is still not clear whether or not they pose any risks to humans or the environment.

This is where risk analyses and life cycle assessments (LCA) come into play, which used to rely strongly on animal experiments when it came to determining the harmful effects of a new substance, including toxicity. Today, research is required to reduce and replace animal experiments wherever possible. Over the past 30 years, this approach has led to a substantial drop in animal testing, particularly in toxicological tests. The experience gained with conventional chemicals cannot simply be transferred to novel substances such as nanoparticles, however. Empa scientists are now developing new approaches, which should allow another substantial reduction in animal testing while at the same time enabling the safe use of nanomaterials.

"We are currently developing a new, integrative approach to analyze the risks of nanoparticles and to perform life cycle assessments," says Beatrice Salieri from Empa's Technology and Society lab in St. Gallen. One new feature, and one which differs from conventional analyses, is that, in addition to the mode of action of the substance under investigation, further data is included, such as the exposure and fate of a particle in the human body, so that a more holistic view is incorporated into the risk assessment.

These risk analyses are based on the nanoparticles' biochemical properties in order to develop suitable laboratory experiments, for example with cell cultures. To make sure the results from the test tube ("in vitro") also apply to the conditions in the human body ("in vivo"), the researchers use mathematical models ("in silico"), which, for instance, rely on the harmfulness of a reference substance. "If two substances, such as silver nanoparticles and silver ions, act in the very same way, the potential hazard of the nanoparticles can be calculated from that," says Salieri.

But for laboratory studies on nanoparticles to be conclusive, a suitable model system must first be developed for each type of nanoparticle. "Substances that are inhaled are examined in experiments with human lung cells," explains Empa researcher Peter Wick who is heading the "Particles-Biology Interactions" lab in St. Gallen. On the other hand, intestinal or liver cells are used to simulate digestion in the body.

This not only determines the damaging dose of a nanoparticle in cell culture experiments, but also includes all biochemical properties in the risk analysis, such as shape, size, transport patterns and the binding – if any – to other molecules. For example, free silver ions in a cell culture medium are about 100 times more toxic than silver nanoparticles bound to proteins. Such comprehensive laboratory analyses are incorporated into so-called kinetic models, which, instead of a snapshot of a situation in the test tube, can depict the complete process of particle action.

Finally, with the aid of complex algorithms, the expected biological phenomena can be calculated from these data. "Instead of 'mixing in' an animal experiment every now and then, we can determine the potential risks of nanoparticles on the basis of parallelisms with well-known substances, new data from lab analyses and mathematical models," says Empa researcher Mathias Rösslein. In future, this might also enable us to realistically represent the interactions between different nanoparticles in the human body as well as the characteristics of certain patient groups, such as elderly people or patients with several diseases, the scientist adds.

As a result of these novel risk analyses for nanoparticles, the researchers also hope to accelerate the development and market approval of new nanomaterials. They are already being applied in the "Safegraph" project, one of the projects in the EU's "Graphene Flagship" initiative, in which Empa is involved as a partner. Risk analyses and LCA for the new "wonder material" graphene are still scarce. Empa researchers have recently been able to demonstrate initial safety analyses of graphene and graphene related materials in fundamental in vitro studies. In this way, projects such as Safegraph can now better identify potential health risks and environmental consequences of graphene, while at the same time reducing the number of animal experiments.

Swiss Quality Principles plus Innovation Strength: Hygiene and Material Protection from SANITIZED 

SANITIZED AG is known as a worldwide leading Swiss company in hygiene functions and material protection for textiles and plastics. Globally oriented, pioneering work is done with federal thoroughness in the development of innovative, effective and safe technologies for antimicrobial equipment. Textination had the opportunity to speak to CEO Urs Stalder about the growing importance of hygiene in times of the pandemic.

Founded in 1935, the majority ownership of the public company SANITIZED still lies with the founding families. You are the market leader in Europe in hygiene functions and material protection for textiles and plastics. If you had to introduce yourself in 100 words to someone who doesn't know the company: What influenced you in particular in the development of the company and what made it unique?
Preventing odor in shoes, that's how it started in 1935. This is where our business model came from: the antimicrobial protection of plastics and textiles.
SANITIZED develops ready-to-use additives that are individually tailored to the protection goals of the end products and that work, for example, against the development of odors in work clothing, against permastink (resilient odors) in synthetic textiles or against mold growth.
The 360-degree service is unique: This includes backing in product development, support for all regulatory questions and assistance with marketing topics.
SANITIZED AG is globally active and yet committed to Swiss quality principles. More than 400 brands worldwide use the ingredient brand Sanitized^® on their end products.

Think global – act local? You have sister companies in France, the United States and Asia. Your roots and headquarters are based in Switzerland. The pandemic is currently increasing the question of intact supply chains. What does this mean for your company in the future?
Indeed, the broad global positioning enables us to do business locally. The local anchoring results in synergies, also in sourcing. That will be even more important for us in the future. And, of course, the issues of speed and customer proximity are also positive aspects of this approach.

From textiles to plastic surfaces to cans: SANITIZED Preservation AG was founded in 2018 to take care of colors and coatings. SANITIZED is thus opening up another market. Which markets are you particularly interested in and which product areas do you feel particularly challenged by?
Customers want paints and varnishes without solvents, which is better for people and the environment. But with the alternative water-based products, there is a high risk of contamination by microbes. This starts with the production, continues with the storage in the can and also in the application. The result is mold formation.
Antimicrobial protection for paints or coatings is particularly relevant in hygiene-sensitive areas of industrial production and, of course, in the medical environment. The risk of contamination and mold multiplies in regions with high air humidity. This is another reason why India is a growth market for this business area.   

To break new ground means decisiveness, overcoming fears - and thus the courage to fail. Not every project can succeed. In retrospect - about which entrepreneurial decision are you particularly glad to have made it?
Let me mention just three decisions that are important for corporate development: This is definitely the foundation of the SANITIZED Preservation division. This is about the antimicrobial protection of paints and varnishes. This also includes setting up our in-house TecCenter, in which we can perform laboratory services even faster. It was recently accredited by the International Antimicrobial Council. And right now it is the sales cooperation with Consolidates Pathway on the US market for our textile hygiene function solutions.

You state that innovation is embedded in the company's DNA. How do you live your inno-vation management and which role do the requirements of end consumers and your indus-trial customers play in this setting?
We ourselves as well as our global sales partners are in close contact with the manufacturers of textile products. This is also why we know the requirements and needs of the market. Sustainability is emerging from the niche in the mass market.
This is exactly what our product Sanitized^® Odoractiv 10 has been developed for and awarded by the Swiss Innovation Award.
It is a dual-acting, biocide-free, patented technology against odor development and odor adsorption in textiles. Many customers appreciate our expertise and use it in the development of new products to create innovative textiles with additional benefits for the requirements of the market.

Tailor-made or solutions only for major customers? The topic of individualization up to lot size 1 takes up a lot of space today. What do you think about individual product solutions - or can you cover everything with the SANITIZED portfolio comprising 40 products?
We have a very versatile technology “kit” at our disposal. It is part of our daily business to respond individually to the special customer needs and the respective product requirements. We offer tailor-made recipes for this and our extensive application know-how flows into the advice for the individual application situation at the customer.

There are various definitions for sustainability. Customers expect everything under this term - from climate protection to ecology, from on-site production in the region to the ex-clusion of child labor, etc. Textile finishing does not always sound unproblematic. Public procurement is increasingly switching to sustainable textiles. What does this mean for SANITIZED and what do you do to bring the concept of sustainability to life for your company, and which activities and certifications do you focus on?
Resource conservation is a key issue for us. Since we “think” about the topic of sustainability along the entire production chain, including in research and development, resource-saving application techniques for the textile industry are important to us. Sanitized^® additives can be integrated into standard production processes, so that additional energy is not required for complementary finishing processes.
Our portfolio also includes biocide-free products. Sanitized^® Odoractiv10 prevents odors from sticking to textiles. Sanitized^® Mintactiv uses the natural antibacterial effect of mint and was specially developed for cotton textiles.
And what smells less has to be washed less often. This saves water and electricity and extends the useful life of textiles.
          
SANITIZED supports its customers with a so-called 360° service. What do you mean by that and why don't you concentrate exclusively on the technical aspects of the products?
The SANITIZED brand wants to create real added value for its customers. That is why we have expanded our core competence as a developer and provider of innovative antimicrobial additives with an all-round service. The obvious thing to do is to support the production process, of course that is part of it. Furthermore; we also provide the latest knowledge on regulatory issues - world-wide. And we offer comprehensive marketing assistance for our license partners who use Sanitized^® as an ingredient brand. Making correct advertising statements is important not only in times of Corona. Because it's always about transparency and security for people. Warning letters or delivery stops due to incorrect claims can be prevented.
Cooperation with the institutes is absolutely sensible; after all, it is their job to do research for com-panies that they cannot shoulder on their own. This includes testing facilities, as well as applying for funding, which is only possible in cooperation with research institutes. However, they are public institutions and therefore have different objectives per se than a company: We have to bring a promising idea to the market as quickly as possible to show a profit. A research institute does not have this pressure.

Which goal do you pursue with the website https://www.sanitized.house for example?
Yes, it may seem unusual when SANITIZED as a B2B company designs a platform for end customers. But more than 400 brands use Sanitized^® as an ingredient brand. So, we are connected to the end customer in this way.
In the virtual house - Sanitized^® the house -, visitors can playfully experience in which areas of life hygiene and material protection contribute to the quality of life. A click in the wardrobe links to products - including brand names - that have been equipped with Sanitized^®: clothing in the wardrobe, the carpet in the living room or the towel in the bathroom. The best thing to do is try it yourself.

The company is working consistently on implementing Sanitized^® as a brand. The hygiene function for textiles and plastics shall be documented and thus offer added value to customers and consumers. Co-branding is not always welcome, especially in the clothing, sports and outdoor sector. How rocky was the road until Sanitized^® was advertised as an ingredient brand by 400 license partners on the product?
Of course, there are brands that do not want a second brand on their end product. But a trend is causing more and more manufacturers to rethink: Customers are increasingly asking questions about ingredients and their origins. Elucidation and transparency are growing needs. And that's exactly what we contribute to. In addition, this is an opportunity for a textile brand to stand out positively in the flood of suppliers. Differentiation through added value - donated by Swiss technology from SANITIZED. Those arguments work worldwide.

You have a diversified network. Just to mention to two of them - you have been a system partner since the foundation of bluesign^® and you work closely with Archroma in sales matters. In which aspects do you see the special value of partnerships? Are there segments existing where you can imagine new partners and collaborations?
Partnerships are important and work if all pursue common goals and can mutually fertilize each other. For example, the partnership with the company Consolidates Pathway in the United States is brand new one.

For which socially relevant topics do you see a particularly great need for innovation and action in the next 5 years? What is your assessment that your company will be able to offer solutions for this with its products? And what role do the experiences from the corona pandemic play in this assessment?
Nobody can predict what the corona pandemic will change in the long term. Environmental protection and thus the conservation of our resources is and remains an important issue.
The fact that the textile industry can make a big contribution to this is slowly gaining awareness among the masses. Keywords are cheap production or water consumption for jeans production. People are becoming more sensitive to what companies and brands are doing. It will be all the more important to act and communicate openly and transparently.
For SANITIZED, it is a mission and a matter of course that only products with official approvals are used and that we work ac-cording to the bluesign principle. This is where traceability and transparency begin.

Whether biodegradable geotextiles, wearables from thermoplastic elastomers or functional textiles from 3D printers - the scope of plastics developed at the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT is wide.

Insights into these projects were provided from October 16th - 23rd  in Düsseldorf: At the K, scientists presented their work on thermally and electrically conductive, biodegradable, bio-based compounds as well as compounds suitable for additive production.
 
Textile composites from the 3D printer
In the "AddiTex" project, plastics were developed that are applied to textiles in layers using 3D printing and give them functional properties. A special challenge in the development was the permanent adhesion: The printed plastic had to be both a strong bond with the textile and sufficiently flexible to be able to participate in movements and twists.

A flexible and flame-retardant compound was developed, which is particularly suitable for use in the field of textile sun and sound insulation, as well as a rigid compound, which is used, among other things, for reinforcing the shape of protective and functional clothing.

Geotextile filter for technical-biological bank protection
Geotextile filters for technical-biological bank protection are the focus of the "Bioshoreline" project. It stands for gradually biodegradable nonwovens, which allow a near-natural bank design of inland waterways with plants. They consist of renewable raw materials and are intended to stabilize the soil in the shore area until the plant roots have grown sufficiently and take over both filter and retention functions. The ageing and biodegradation of the fleeces begin immediately after installation, until the fleeces are gradually completely degraded.

Prototypes of the geotextile filters are currently being tested. Female scientists evaluate the plant mass formed above and below ground with and without geotextile filters as well as the influence of the soil type on plant growth and the biological degradation of the filter.

Wearables made of thermoplastic elastomers
In addition, Fraunhofer UMSICHT is developing novel, electrically conductive and flexible compounds that can be processed into thermoplastic-based bipolar plates. These plastics are highly electrically conductive, flexible, mechanically stable, gas-tight and chemically resistant and - depending on the degree of filling of electrically conductive additives - can be used in many different ways. For example, in electrochemical storage tanks (batteries), in energy converters (fuel cells), in chemical-resistant heat exchangers or as resistance heating elements.

Another possible field of application for these plastics: Wearables. These portable materials can be produced easily and cheaply with the new compounds. It is conceivable, for example, to form garments such as a vest by means of resistance heating elements. The idea behind this is called Power-to-Heat and enables the direct conversion of energy into heat.
