From the Sector

Kelheim Fibres, a manufacturer of specialty viscose fibres, showcases its latest developments at this year's Global Fiber Congress in Dornbirn. The focus is on innovative solutions that not only promote environmental sustainability but also strengthen the European supply chain.

In his presentation "Towards high performing plant-based AHP products - a joined approach of Pelz and Kelheim Fibres," Dr. Ingo Bernt, Project Leader of Fiber & Application Development at Kelheim Fibres, together with Dr. Henning Röttger, Head of Business Development at PelzGROUP, introduces the development of a plastic-free yet high-performance panty liner. The water-repellent Kelheim specialty fibre Olea plays a crucial role in both the top and backsheet of the panty liner. This product emerged from the ambition to offer eco-friendly alternatives to conventional disposable hygiene solutions without compromising on product performance.

A similar approach is pursued in the second presented project. Under the title "Performance Fibres meet Sustainable Design - example of a reusable Baby Diaper," Natalie Wunder, Project Leader from Kelheim Fibres' New Business Development team, together with Caspar Böhme, Co-Founder of Sumo, introduce the washable and reusable SUMO diaper. Made from biobased materials and featuring a unique construction with Kelheim specialty fibres, this combination offers double environmental benefits compared to conventional disposable baby diapers.

Both the panty liner and the SUMO diaper are manufactured entirely in Europe, resulting in shorter transportation routes and a reduced CO2 footprint. Moreover, these innovations contribute to strengthening the European textile and nonwovens industries by fostering innovation within Europe.

Using recovered resin from discarded car bumpers, Autoneum’s sustainable Re-Liner technology transforms a previously unusable waste product into lightweight and durable wheelhouse outer liners. In addition to their high recycled content, the eco-friendly components require significantly less energy to produce than conventional alternatives. The innovation presents another important step towards a more sustainable circular economy and has now been nominated for the 2023 PACE Award.

Autoneum has been selected as one of the finalists for the 2023 Automotive News PACE Awards. Entering its 29th year, this prestigious award honors superior innovation, technological advancement and business performance among automotive suppliers.

Re-Liner is based on a core of polyolefins recovered from post-consumer bumpers and has a textile top layer made of fibers from recycled materials. “Autoneum has recognized the untapped potential of recovered resin from automotive bumper covers as a resource and is giving this former waste product a second life,” explained Dan Moler. “The core resin of Re-Liner is 100% automotive post-consumer recycled material, not just a filler or additive to a virgin material. Lightweight, durable, and sustainable wheelhouse outer liners based on this technology are expected to reduce waste generated by bumper covers by nearly one million kilograms in 2023.”

For more than a quarter century of a century, the PACE Award has honored innovations driven by automotive suppliers. The award is known in the global automotive industry for identifying and recognizing the latest game-changing innovation: from the plant floor to the product to the showroom. In 2000, Autoneum (then Rieter Automotive) already received a PACE Award for its Ultra-Light technology. In addition, two of the Company’s technologies have also been nominated as finalists in the past: Ultra-Silent in 2010 and Theta-Fiber in 2012.

How does a future-proof, circular and sustainable plastics economy look like? The answer is a balance ranging from plastics reduction to a sustainable use of recyclable plastics. After all, the increasing demand for plastics in high-value applications such as food packaging, car parts or synthetic textiles requires a holistic change. With four strategic approaches, researchers from the German institute Fraunhofer UMSICHT and the Dutch institute TNO now provide insights into how this future scenario could look like in their recently published white paper "From #plasticfree to future-proof plastics". Both organizations also start a hands-on platform for plastics in a circular economy: European Circular Plastics Platform – CPP aimed at removing existing barriers and sharing of promising solutions.

Versatile and inexpensive materials with low weight and very good barrier properties: That's what plastics are. In addition to their practical benefits, however, the materials are also associated with a significant share of mankind's greenhouse gas emissions. The production and use of plastics cause environmental pollution and microplastics, deplete fossil resources and lead to import dependencies. At the same time, alternatives - such as glass packaging - could cause even more environmental burden or have poorer product properties.

Researchers from TNO and Fraunhofer UMSICHT have elaborated a white paper that provides a basis for the transformation of plastics production and use. They consider the integration of the perspectives of all stakeholders and their values and the potential of current and future technologies. In addition, the functional properties of the target product, the comparison with alternative products without plastics, and their impact in a variety of environmental, social and economic categories over the entire life cycle are crucial. In this way, a systematic assessment and ultimately a systematic decision as to where we can use, reject or replace plastics can be realized.

Strategies for the Circular Economy
As a result, the researchers describe four strategic approaches for transforming today's largely linear plastics economy into a fully circular future: Narrowing the Loop, Operating the Loop, Slowing the Loop, and Closing the Loop. By Narrowing the Loop, the researchers recommend, as a first step, to reduce the amount of materials mobilized in a circular economy. Operating the Loop refers to using renewable energy, minimizing material losses, and sourcing raw materials sustainably. For Slowing the Loop, measures are needed to extend the useful lifetime of materials and products. Finally, for Closing the Loop, plastics must be collected, sorted and recycled to high standards.

Individual strategies fall under each of the four approaches. While the ones under Operating the Loop (O strategies) should be applied in parallel and as completely as possible. According to the researchers, the decision for the strategies in the other fields (R strategies) requires a complex process: “Usually, more than one R-strategy can be considered for a given product or service. These must be carefully compared in terms of their feasibility and impact in the context of the status quo and expected changes”, explains Jürgen Bertling from Fraunhofer UMSICHT. The project partners have therefore developed a guiding principle for prioritization based on the idea of the waste hierarchy.

A holistic change, as we envision it, can only succeed if science, industry, politics and citizens work together across sectors. “This implies several, partly quite drastic changes at 4 levels: legislation and policy, circular chain collaboration, design and development, and education and information. For instance, innovations in design and development include redesign of polymers to more oxygen rich ones based on biomass and CO2 utilisation. Current recycling technologies have to be improved for high quantity and quality recycling,” explains Jan Harm Urbanus from TNO.

Hands-on platform for cross-sector collaboration
“Therefore, in a next step, TNO and Fraunhofer UMSICHT are building a hands-on platform for plastics in a circular economy: European Circular Plastics Platform – CPP," explains Esther van den Beuken, Principal Consultant from TNO. It will give companies, associations and non-governmental organizations the opportunity to work together on existing barriers and promising solutions for a Circular Plastics Economy. The platform will also offer its members regular hands-on workshops on plastics topics, roundtable discussions on current issues, and participation in multi-client studies on pressing technical challenges. Regular meetings will be held in the cross-border region of Germany and the Netherlands as well as online. The goal is to bring change to the public and industry.

ERCA, Patagonia® and YKK announce the implementation of ERCA’s REVECOL®, a sustainable, innovative chemical agent, in YKK’s dyeing processes at their Vietnam production sites transforms common waste material, such as exhausted vegetable cooking oil, into an upcycled, certified high performance, safe textile chemical. ERCA has invested in circular practices to take waste material and use them as feedstocks to create new responsible chemical products.

Always searching for new sustainable innovations, REVECOL® caught the attention of Patagonia®. Driven by the goal to utilize non-extractive chemistry in their supply chain wherever possible, the brand teamed up with ERCA and trim supplier YKK to deploy REVECOL®.

REVECOL® LV-TS has a carbon footprint that is 72% lower* than the more conventional chemical auxiliaries produced by ERCA. Today ERCA produces a wide range of high-performance chemical auxiliaries made from used vegetable oil that are ZDHC, bluesign® approved and GRS certified.

ERCA is one of the first companies to have GRS certified chemical products, opening the door to circular chemical auxiliaries.

As part of their Sustainability Vision 2050, YKK is constantly working to deploy more sustainable chemical processes in their production. The ability to replace a commonly used dye chemical with a lower impact version was a no-brainer for YKK’s Vietnam management. REVECOL® is not only more sustainable, it is also more efficient, reducing the use of the dyeing auxiliary by 20% to 30%, thus  helping to lower YKK’s overall chemical usage.

ITA Aachen - Digital ring spinning tester for recycled fibres enables spinning of fine yarns with high recycled fibres content
The Institut für Textiltechnik of RWTH Aachen University (ITA) will be exhibiting a digital ring spinning tester, which spins recycled fibres directly and conventionally with a particularly high content of 60-70 percent. Up to now, recycled yarns have mainly been rotor-spun in this blend ratio. This results in rather coarse yarns and is not suitable for finer textiles such as outerwear. Ring spinning of recycled yarns now enables the spinning of finer yarns and thus a higher application level for recycled materials.

A unique selling point of the ITA ring spinning tester is the simultaneous spinning in the direct spinning process from the sliver and in the classic ring spinning process. For this purpose, the strength and elongation of the spun yarn are determined online and digitally for the first time. The real-time measurement allows process parameters and yarn properties to be adjusted iteratively and quickly. The ring spinning tester was upgraded from an existing tester to Industry 4.0 standard and is operated via a tablet. Operation via tablet enables the adjustment of process parameters including online quality monitoring remotely from anywhere in the world.
 
For this purpose, the ring spinning tester is also able to produce fine ring spun yarns. These yarns made from recycled material opens up a multitude of further fields of application for woven and knitted goods. Now, for example, clothing and technical textiles can be made from recycled material, the production of which was not possible before - such as outerwear made from recycled material. The development of new industries and fields of application opens up new market potential for recycled yarns - also and especially for processing in Europe. This creates the opportunity to preserve key technologies and jobs in cost-intensive locations.

ITA Augsburg - Recycling Atelier: Walk4Recycling
The Recycling Atelier of the Institut für Textiltechnik Augsburg gGmbH on stand H3-A207 presents the textile recycling from used textiles into new products via the various process steps and, together with the industrial partners, opens up solution paths for industrial implementation.

Under the headline "Walk4Recycling", a tour of the fair shows the cycle of used textiles from used knitwear into a new knitted pullover via a ring yarn made from a blend of 65 percent recycled cotton and 35 percent virgin polyester. The key innovation here is the high proportion of recycled fibres from post-consumer textiles for a ring yarn of this fineness. Today, mainly coarse rotor yarns for low-quality textiles are spun from these materials. The industrial partners participating in the Walk4Recycling are partners of the Recycling Atelier and contribute with their technologies to the fact that fibre material from old clothes can be processed in various process stages into a yarn of new value and high-quality ready-made garments.

The Walk4Recycling offers visitors the opportunity to experience a complete recycling cycle with the numerous process stages from tearing the old textiles, preparing and spinning the fibres and knitting a new jumper live during the fair. Get detailed information on the mechanical recycling of clothing via QR code, website and flyer about the participating exhibitors and their machines and technologies. A short movie will give you additional insights into the various processes involved in the production of the jumper.

Carbios shares the Foundation’s commitment to accelerate the transition to a circular economy, especially in the areas of plastics and fashion. By joining the Ellen MacArthur Foundation’s Network, Carbios will connect with other leaders within the Foundation’s leading circular economy network of businesses, policymakers, academia, innovators, and thought leaders worldwide.

Carbios fully adheres to Ellen MacArthur Foundation’s vision for a circular economy for plastic. Its biorecycling and biodegradation technologies already match the actions defined by the Foundation:

• Eliminate all problematic and unnecessary plastic items
• Innovate to ensure that the plastics we do need are reusable, recyclable, or compostable
• Circulate all the plastic items we use to keep them in the economy and out of the environment

Through ambitious collaborative projects, plastics and fashion are two topic areas for the Foundation and are also at the heart of Carbios’ activities. Providing actionable solutions to support brands’ ambitious commitments for sustainable packaging and textile industries, Carbios has founded two consortiums: one in the packaging industry established with L’Oréal in 2019, which has since been joined by Nestlé Waters, PepsiCo and Suntory Beverage & Food Europe; another created in 2022 in the textile industry with apparel and fashion brands On, Patagonia, PUMA, PVH Corp. and Salomon. Together, the consortium members develop solutions promoting the recyclability and circularity of their products.

Joining the Ellen MacArthur Foundation’s Network takes Carbios’ circular economy actions one step further. Carbios recently underscored its commitment to circularity and environmental responsibilities by publishing its first Sustainability Report at the end of 2022^[1]. In 2019, Carbios’ biorecycling and biodegradable solutions were among the first innovations to be labelled “Efficient Solution” by the Solar Impulse Foundation^[2].
