Redefining textile waste sorting

To meet future demands on the amount of textile waste which needs to be collected and sorted, as well as the demand on recycling feedstock, it is necessary to match the demand and need for sorting of waste in Europe and create cost efficiency sorting capacities with larger scale and automation are necessary.

In an online session “Redefining Textile Waste Sorting: Impulses and findings for the future of next-gen sorting facilities” Texaid and partners talk about the current state of development and the challenges for the future.  Anna Pehrsson (Texaid), Gesine Köppe (ITA Augsburg GmbH) and partners present the results of a Technology Assessment conducted within The Transform Textile Waste into Feedstock Project (initiated by TEXAID within the ReHubs initiative) to assess the best available sorting techniques and process.

TEXAID x Triumph: Expansion of international in-store collection program

As a leading company in the collecting, sorting, reselling and recycling of post-consumer textile waste, TEXAID has enabled the recycling of post-consumer textile waste into new textiles and clothing. Working together with brands and retailers, TEXAID and our partners are continuing to take action to shift from a linear to a circular system.

Since 2022, TEXAID has partnered with Triumph International, operating their in-store collection program, “Together We Grow”, for 160 stores across Austria, Denmark, France, Germany, the Netherlands and Switzerland. Given the success of the program, starting April 2023, in-store take back has been expanded to an additional 108 stores across Belgium, Czech Republic, Hungary, Luxembourg, Poland, Portugal, Sweden and Spain. Customers bring in their worn garments and TEXAID manages the collected clothing in alignment with the EU waste hierarchy, sending each item to its next most sustainable lifecycle. TEXAID is pleased to be partnering with Triumph International to offer in-store take back, at scale, across Europe. For every 5 kg collected, Triumph plants a tree in partnership with Treedom.

TEXAID x PUMA partnership for Swiss RE:FIBRE take back program

As a leading company in the collecting, sorting, reselling, and recycling of post-consumer textile waste, TEXAID has enabled the recycling of post-consumer textile waste into new textiles and clothing. Working together with brands and retailers, TEXAID and their partners are continuing to take action to shift from a linear to a circular system.

Today’s linear system of «take – make – waste» needs to change. New textiles are produced used and discarded instead of putting them to a second use. The production of new textiles requires natural resources that are limited, and the current system has a significant negative impact on our planet. The transition to a circular system, where garments are kept in use for longer, is an opportunity to harness untapped potential around customer loyalty, economic growth, and ecological sustainability.

Aligned with the launch of the PUMA Switzerland 23/24 Women’s World Cup home jersey, PUMA and TEXAID have partnered for the Swiss division of their RE:FIBRE Program. PUMA is working to have a more sustainable, long-term solution for recycling polyester jerseys. To achieve this goal, they have developed their RE:FIBRE Program, which transforms textile waste, along with other used materials, into new textiles.

To enable this textile to textile program in Switzerland, specific feedstocks are requires, which is TEXAID’s role as the operator of the collection and sorting. Newly launched in the PUMA Zurich location at Jelmoli, customers can bring garments of all brands and deposit them in-store. TEXAID collects and sorts all deposited items, sending eligible polyester garments into the PUMA RE:FIBRE program, to be recycled into new garments. All other garments are channeled by TEXAID to their next life cycle.

New project “Transform Textile Waste into Feedstock”

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.

Swiss Textile Recycling Project TEXCIRLCE

After two years of joint collaboration and research the Swiss Textile Recycling Project “Texcircle” comes to an end. Partners and stakeholders have worked on the vision of a textile cluster where materials flow in circular loops. The goal of the project was to develop high-quality yarns and products incorporating such a large amount of recycled textiles as possible. In the end, several product prototypes from carpets, socks, and curtains to pullovers, padding and accessories have been developed with at least 50 % recycled fiber up to 80 % recycled fibers and yarns.

Europe has a waste problem of 7.5 million waste of which only 30-35 % is collected and less than 1 % of the textile and clothing worldwide is recycled into textiles and clothing again. It is as well found that around 80 % of the impact of a textile product lies in the design.

Together with the design research expertise of the Lucerne University of Applied sciences and arts, the spinning expertise of Rieter and the sorting and collection expertise of Texaid, systems should be created where products of high quality can be produced of recycled fiber. On board were the expertise of further Cluster partners of Brands, Retailers, and the public sector to see how a joint Cluster and system coukld be established.

The Project Texcircle and cluster is led by the Lucerne University of Applied Sciences and Arts – Art  & Design, and in collaboration with Coop, Rieter, Jacob Rohner AG, Ruckstuhl AG, TEXAID as well as workfashion.com ag. Furthermore, Bundesamt für Zivildienst ZIVI, NIKIN AG, and Tiger Liz Textiles are supporting the project. The project is funded by Innosuisse.

Furthermore, collaboration partners from all over Europe contributed to the project to enable these prototypes and systems.

Through joint developments from the design, the collecting, sorting trials, tearing, and spinning trials until the actual production trials and product testing. The partners were able to recycle 2.5 Tons of pre-and post-consumer textile waste into product prototypes with a promising commercial interest. From socks, west, and pullovers to non-woven felts and accessories to carpets and curtains. Through our 2 years of collaboration, the teamcame across several hurdles in the textile recycling value chain which could be tackled. This was a proof of concept that a circular system is possible and the industry now has to enable this at full scale.

CISUTAC: New European innovation project on circular & sustainable textiles

Launched this September, the new Horizon Europe project CISUTAC will support the transition to a circular and sustainable textile sector. As part of a consortium of 27 partners working on the project, TEXAID will among others support the project with sorting, disassembly and repair trials.

The production and consumption of textile products continue to grow, together with their impact on the environment, due to a lack of reuse, repair and recycling of materials. Quality, durability, and recyclability are often not being set as priorities in the design and manufacturing of clothing (EU Strategy for Sustainable and Circular Textiles, March 2022).  

CISUTAC aims to remove current bottlenecks in order to increase textile circularity in Europe. The objective is to minimise the sector’s total environmental impact by developing sustainable, novel, and inclusive large-scale European value chains.

CISUTAC aims to remove current bottlenecks in order to increase textile circularity in Europe. The objective is to minimise the sector’s total environmental impact by developing sustainable, novel, and inclusive large-scale European value chains.  

The project will cover most parts of the textile sector by working on two material groups representing almost 90% of all textile fibre materials (polyester, and cotton/cellulosic fibres), and focusing on products from three sub-sectors experiencing varying circularity bottlenecks (fashion garments, sports and outdoor goods, and workwear).  

CISUTAC will follow a holistic approach covering the technical, sectoral and socio-economic aspects, and will perform three pilots to demonstrate the feasibility and value of:

  • Repair and disassembly
  • Sorting (for reuse and recycling)
  • Circular garments through fibre-to-fibre recycling and design for circularity

To realise these pilots, the consortium partners will:

  • Develop semi-automated workstations
  • Analyse the infrastructure and material flows
  • Digitally enhance sorting operations (for reuse and recycling)
  • Raise awareness among the consumers and the textile industry

As part of the CISUTAC consortium, TEXAID, will conduct different trials of sorting, repair, and disassembly, and be active in the LCA and Standardisation work packages.

Transforming textile waste into feedstock

Europe has a 7-7.5-million-ton waste problem, of which only 30-35% is collected today. The ReHubs initiative launched in 2020 has now completed a Techno Economic Master Study (TES) and it sheds light on key figures and options to collaborate to solve the European waste problem.

In two and a half year all EU member states are obliged to separately collect textile waste. Currently there are no large-scaled plans to use that waste.  The largest portion of the waste (around 85%) comes from households.

In two and a half year all EU member states are obliged to separately collect textile waste. Currently there are no large-scaled plans to use that waste.  The largest portion of the waste (around 85%) comes from households.

The ReHubs initiative brings together key European and world players to solve the textile waste problem by transforming “waste” into a resource and to boost textile circular business models at large scale. The completed TES has accessed critical information on solving the European waste problem. It is estimated that to reach a collection rate from 18 to 26 percent by 2030, 7 billion euro will be needed. Once matured and scaled, the textile recycling industry could become a profitable industry with a total market size of 6-8 billion € and around 15,000 direct new jobs by 2030. As a first step the ReHubs Initiative announces different actions forwards, including projects on this pathway, which one is to transform textile waste into feedstock.

TEXAID has been supporting ReHubs since the start and contributed significantly involved to the Business Council and the Steering Committee of the initiative. As strongly committed industry leader TEXAID is taking the lead on the project to transform textile waste into feedstock for recycling processes. In order to handle the increasing quantities of post-consumer textile waste a massive scale up of sorting and preparation for recycling of used textiles is needed. TEXAID is committed to lead the work on developing new technologies and building up additional capacities for the handling and preparing of textile waste for textile recycling in Europe. In a first phase this involves the built up of a new sorting and pre-processing facility with the capacity of 50’00 tons p.a. by 2024.

TEXAID supports the Swiss textile recycling ecosystem with professional collecting and sorting of textiles

TEXAID as a professional collector and sorter with roots in Switzerland contributes to this ecosystem to enable the textile-to-textile recycling.  The creation of Swiss Textile Recycling Ecosystem marks a key milestone in the upscaling of Worn Again Technologies’ recycling process technology with technology scale-up partner Sulzer Chemtech in Winterthur. It also supports its ambition to create a circular economy where non-reusable, hard-to-recycle textiles can be reintroduced into supply chains to become new fibers.

To cause a paradigm shift in the fashion industry and realize true circularity requires all members of the value chain to be on the same page and working towards the same goals. The Swiss Textile Recycling Ecosystem is a network comprising fabric and textile manufacturers, waste collectors and sorters, as well as retailers, brand owners and technology providers – all coordinated by Swiss Textiles. All these parties will cooperate to make their shared vision of a more sustainable fashion industry a reality, where used textiles can be recycled into new textiles.

TEXAID enables Circularity Project R[ECO]LLECT

TEXAID with its Spanish subsidiary PERCENTIL enable Springfield to put its commitment to sustainability into action through implementing a circularity pilot project with the aim of giving a second life to second-hand garments. As part of the Tendam Group, who operates more than 2000 stores in 79 countries, Springfield partners with the TEXAID group, leading in the industry of collecting, sorting, reselling and recycling used garments, to launch the R[ECO]LLECT initiative.

Take-Back Program R[ECO]LLECT
With "the future is circular" as their call to action, the project is called R[ECO]LLECT and refers directly to the collection of all second-hand garments in good condition, to meet three clear sustainability objectives of Springfield: reduce the pressure on natural resources, reduce CO2 emissions and reduce the amount of textile waste.

R[ECO]LLECT was launched in May 2022 as a pilot project in 16 Springfield stores in Spain across different cities and provinces.

TEXAID’s Spanish subsidiary PERCENTIL is a strategic partner of Springfield in this step towards sustainability. The motto of PERCENTIL is that "there is nothing more sustainable than what you already have in your closet", and it is an intermediary between people who want to get rid of clothes and those who are looking to buy almost new clothes from brands recognized for their design and quality, but at a much lower price. In this way, textile overproduction is reduced, and the environmental impact is reduced. In addition, PERCENTIL receives the clothes, sorts them and takes care of giving them a second life.

Vom alten Pulli zum neuen Teppich

Hochschule Luzern und Texaid erforschen, wie gesammelte Kleidung besser recycelt werden kann

Über ein Drittel der gesammelten Altkleider können höchstens noch als Putzlappen oder Reisswolle wiederverwendet werden. Texaid und Forschende der Hochschule Luzern wollen den textilen Kreislauf nun weiter schliessen. Es hat sich gezeigt: Aus Alttextilien lassen sich Garn und Vlies für neue Teppiche und Dämmstoffe herstellen.

Hochschule Luzern und Texaid erforschen, wie gesammelte Kleidung besser recycelt werden kann

Über ein Drittel der gesammelten Altkleider können höchstens noch als Putzlappen oder Reisswolle wiederverwendet werden. Texaid und Forschende der Hochschule Luzern wollen den textilen Kreislauf nun weiter schliessen. Es hat sich gezeigt: Aus Alttextilien lassen sich Garn und Vlies für neue Teppiche und Dämmstoffe herstellen.

Texaid sammelt in der Schweiz jährlich rund 37 000 Tonnen Altkleider und sorgt dafür, dass diese ökologisch sinnvoll wiederverwendet werden. 30 Prozent der gesammelten Textilien sind in zu schlechtem Zustand, um sie als Secondhand-Kleidung weiterzutragen – Tendenz steigend, da der Trend hin zu billigen und billig produzierten Kleidern anhält. Die Frage war: Lassen sich diese Textilien hochwertig recyceln? Forscherinnen und Forscher der Hochschule Luzern und Texaid entwickelten Methoden, um die Altkleidung in der Schweiz zu einem groben Garn zu verspinnen, das sich gut für Teppiche eignet. Aus den kürzeren Fasern und sogar aus dem Staub, der beim Reissen der Stoffe entsteht, stellten Designforscher und Materialforscherinnen Prototypen her, die beispielsweise zur Schalldämmung genutzt werden könnten.

Prozesse analysiert, Anwendungen optimiert

Texaid verfolgt den «Close the Loop»-Ansatz: Sie will textile Kreisläufe nachhaltig und ganzheitlich schliessen und für den Rohstoff aus Altkleidern neue und auch höherwertige Verwendungen finden. Sie hat dafür das Projekt «Texcycle» ins Leben gerufen, eine Zusammenarbeit von Texaid, der Hochschule Luzern und Coop, gefördert durch Innosuisse.

Eine designgetriebene Forschung bot die Möglichkeit, die hochkomplexe Nachhaltigkeitsproblematik der textilen Kreisläufe neu anzugehen. Dafür mussten die Forschenden folgende Fragen beantworten: Welche textilen Materialien liegen nach heutigen Sortiermöglichkeiten der Altkleideraufbereitung vor? Wie lassen sie sich auf welche Art und Weise neu verarbeiten? Wie könnte eine Produktepalette mit neu gewonnenen Materialien aus Alttextilien aussehen?

Nicht nur nach Kleidungsart, sondern auch nach Material trennen

In einem ersten Schritt analysierten die Forscherinnen und Forscher die Prozesse der Altkleideraufbereitung und optimierten sie für neue Anwendungen. «Bisher werden die gesammelten Kleider nach Kleidungsart – z.B. Männerhemd, Damenhose, Mantel – sortiert», erklärt Anna Pehrsson, Recycling Solutions Specialist bei Texaid. Für eine bessere Weiterverwendung spielt aber das Material der Kleidung eine grössere Rolle; nach diesen Kriterien wird derzeit kaum getrennt.

Derzeit wird ein nicht mehr tragbarer Pullover aus Baumwolle zu Putzlappen verarbeitet, obwohl sein Material in hochwertigen Produkten gefragt wäre. Das wollen die Forscherinnen und Forscher ändern. «Wir haben vorgeschlagen, sechs Materialkategorien einzuführen», sagt Brigitt Egloff, Wissenschaftliche Mitarbeiterin im Departement Design & Kunst. So liessen sich beispielsweise Produkte mit einem hohen Baumwollanteil gesondert sortieren. Denn je reiner ein Material ist, umso leichter lassen sich Weiterverwendungsmöglichkeiten finden.

Teppichprototyp

In der Wollspinnerei Huttwil AG wurden Materialien zu Faden versponnen. Dabei stellte sich heraus, dass die besten Resultate erzielt werden, wenn das recycelte Material aus den Altkleidern mit Wollabfällen aus der Spinnerei kombiniert wird. So lässt sich ein 100%-Recycling-Garn herstellen und der grobe Faden zu Teppichen weiterverarbeiten. Erste Prototypen sehen vielversprechend aus.

Recycelte Kleidung als Dämmmaterial

Auch die Designforscher von Design & Kunst und die Materialforscher des Departements Technik & Architektur können erste Prototypen vorweisen. Sie nutzten die kurzen Fasern zur Herstellung von Vlies, einer losen, nicht gewebten Verbindung von Fasern, und entwickelten verschiedene Anwendungsmöglichkeiten als Dämmmaterialien. Diese können vor allem im Bereich der Schalldämmung von Innenräumen oder von Fassaden Verwendung finden. Eine Schwierigkeit dabei: «Die technischen Anforderungen an Bauprodukte in der Architektur haben strenge Auflagen und Normen zu erfüllen. Gegensätzliches trifft bei Bekleidung oder textilen Ausstattungen zu», sagt Materialforscherin Susanne Triller und Wissenschaftliche Mitarbeiterin im Departement Technik & Architektur. Damit das Material im Bau verwendet werden darf, muss bewiesen sein, dass es schadstofffrei ist und als nicht brandgefährlich zertifiziert werden kann.

In einem Folgeprojekt könnten nun Wege gefunden werden, aus Alttextilien auch feine Garne zu spinnen – so fein, dass aus ihnen wieder neue Kleider hergestellt werden können.
