From the Sector

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.

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.

The steering committee for the Denim Deal has announced that Haelixa, the Swiss standard in physical traceability, is approved as a new signature. The Denim Deal is an international collaboration of more than 50 private and public sector companies united in the commitment to produce denim more circularly.

The Denim Deal aims to close the loop and achieve change in the value chain. Based in Amsterdam, the group is working towards a circular economy where textile waste no longer exists. The brand and manufacturing members pledge to work towards using 5% recycled post-consumer cotton in all future denim collections and produce 3 million denim jeans made with 20% recycled post-consumer cotton.

Coordination of the Denim Deal is led by Roosmarie Ruigrok, where the objective is to unite potential allies who have made the journey to circularity a priority. She has been working to improve sustainability in textiles for more than two decades and is an expert on enrolling the correct stakeholders to instigate change. Ruigrok states, "a circular supply chain in the textile industry is like a well-prepared machine - it ensures that every part of the production process runs smoothly, from sourcing post-consumer materials to delivering well-made finished products to customers. It not only drives efficiency and profitability but also builds trust among stakeholders and fosters sustainable practices - we welcome Haelixa who offers a trustful traceability solution."

Over the last few years, the demand for the technology in recycled denim has grown as brands are asked to validate their recycling claims. Haelixa’s unique DNA solution marks and traces fibers from the source to retail. Using DNA to mark the recycled post-consumer cotton, Haelixa substantiates claims by testing the final garment to validate that the marked waste is present.

The Denim Deal is pushing to lead the change in how denim is made. Changing the standards of operation is always challenging, and traceability is a key to authenticating recycled claims. “We are committed to promoting the use of recycled fibers through traceability and thrilled to align with this group,” said Holly Berger, Haelixa’s Marketing Director. “The goals of the Denim Deal support our vision for a circular economy.”

Kelheim Fibres, a leading manufacturer of viscose speciality fibres, has joined Recycling Atelier Augsburg. Recycling Atelier Augsburg is a unique centre for research and development in the field of textile recycling. It is located at the Institut für Textiltechnik Augsburg an affiliated institute of Augsburg University of Applied Sciences. The two institutions founded the Recycling Atelier in June 2022 together with twelve partners from the German textile industry.

In the Recycling Atelier, the focus is on the triad of technical and ecological sense as well as economic benefit. In this way, the partners of the Recycling Atelier are standing up against fast fashion, outsourced corporate responsibility and a general decline in raw material quality, which often fuels downcycling - the low-quality reuse - of materials.

As a model factory, the Recycling Atelier Augsburg combines the most important processes of textile recycling and offers holistic and comprehensive research along the value chain," explains Georg Stegschuster, head of the Recycling Atelier Augsburg. The scientists research on all process steps of textile recycling: from material analysis to sorting, preparation and textile processing to sustainable product design. Comprehensive data collection and the use of artificial intelligence as well as innovative materials play a central role.

Kelheim Fibres is a producer of high-quality viscose fibres, which consist of cellulose, the main component of the renewable raw material wood, and are used worldwide for products in areas such as hygiene, textiles, and technical applications.

"In New Business Development as well as Fibre and Application Development, we follow the Open Innovation concept - the cooperation with the Recycling Atelier offers us an ideal platform for this. Here we work with partners to advance sustainability and performance," explains Maik Thiel, project manager at Kelheim Fibres.

Recycled cotton fibres are often very short or of uneven length, which makes further processing of 100 % recycled material a challenge. Adding speciality fibres from Kelheim Fibres should enable the production of high-quality new products, such as nonwovens. In the future, the fibres provided by Kelheim Fibres will also be made from recycled pulp.

Textile waste is a problem in Europe. Out of 7-7.5 million tonnes of textiles discarded every year, 30-35 % are collected separately – and of that quantity, 15-20 % are sorted by medium and larger sorting facilities within the EU. After sorting, 60 % still qualify as wearable clothes, however after a second or third collection-loop, all of the textiles become non-wearable sooner or later. Therefore, fibre-to-fibre recycling is becoming increasingly important to preserve the valuable resources.
 
The textile recycling value chain is not yet mature, but we are on the verge of a turning point, as different fibre-recycling technologies are deployed on a large scale. If successful, the textile recycling industry could reach a recycling rate of 18 to 26 percent of gross textile waste in 2030. This would create economic, social and environmental value that could total 3.5 to 4.5 billion euros in 2030.

Today, there is a sorting gap to achieve a circular economy for textiles in Europe. To feed this new circular value chain, a significant sorting-capacity increase is needed with 150 to 250 sorting and recycling facilities nearby, as the McKinsey-study “turning waste into value” assessed.

There is also a technology and capacity gap in sorting for reuse and recycling to ensure that high quality raw materials from non-wearable textile waste can be made available on a large scale. This is why the “Transform Textile Waste into Feedstock” project was initiated by TEXAID, within the ReHubs initiative together with well-known stakeholders of the textile value chain.

The major outcome of this project will be a sorting-factory blueprint fulfilling the requirements to the future needs of fibre-to-fibre recycling, enabling the future of more sustainable textiles by using recycled fibres. TEXAID, who is leading the project, is committed to build and operate scalable sorting facilities across Europe, the first with a capacity of 50,000 tonnes by the end of 2024.

Companies like Concordia, CuRe Technology, Decathlon, Inditex, Indorama Ventures, L’Atelier des Matières, Lenzing, Marchi & Fildi, PurFi, Södra, Worn Again and others are taking part in the project to jointly evaluate technologies and the business case for scaled sorting for reuse and recycling. ITA Academy GmbH (in cooperation with RWTH Aachen) together with CETIA has been commissioned for the assessment of technologies. The outcome will be an innovative sorting system 4.0, building on cross-functional technologies with digitalization and automation are at the heart.
