matterr at K – Where innovation meets industry

At this year’s K trade fair, matterr took the stage to showcase its technology and demonstrate how it drives circular polyester at an industrial scale. Insightful conversations, strong new connections, and great energy — all together reminds how powerful it is when innovation meets industry. The momentum from Düsseldorf shows: circular transformation is no longer a vision — it’s happening.

The cleantech company matterr was part of this year’s K — The World’s No. 1 Trade Fair for Plastics and Rubber, introducing its patented depolymerization technology to a global audience. At the booth and during its sessions the company shared insights into its first small-scale industrial plant, to be built at Chemiepark Knapsack, which will serve as a blueprint for future large-scale facilities.

On day two, matterr hosted a press briefing together with Ralf Müller and Christoph Kappenhagen from the management board of YNCORIS, and Monika Beck, Head of Business Unit D-A-CH / Spain / Portugal at NRW.Global Business. The message was clear: industrial innovation can start in Germany — and scale across borders.

“With the EU funding and BESTSELLER’s investment, we have reached two important milestones toward building a small-scale industrial depolymerization plant at Chemiepark Knapsack. Our decision to scale in Germany is intentional: the technology was developed here, and we will keep the value creation here. This ensures strategic independence in a key technology driving the global circular transformation in the textile and packaging industries", states Melanie Hackler, CEO of matterr

Project and regional impact

The planned facility, with an annual capacity of around 10,000 tons, will convert hard-to-recycle polyester streams — from textiles to multilayer packaging — into virgin-quality, drop-in feedstock. The technology is specifically designed to handle complex material streams that mechanical recycling cannot handle.

By recovering polyester captured in mixed waste streams currently sent to landfill or incineration, matterr advances decarbonization across the polyester value chain, and contributes to EU circular economy and climate targets – while reinforcing Germany’s role as a hub for industrial innovation.

Scaling up, matterr aims to prove that fossil-free circular solutions work at industrial scale and to set a new benchmark for regenerative supply chains across industries.

“Chemiepark Knapsack offers ideal conditions: infrastructure, energy networks, skilled workforce, and proximity to strong partners across the value chain. For us as a team, it is also about establishing standards and processes that enable fast replication and international roll-out, says Benjamin Rump, COO of matterr.

Recycling pioneer matterr to build plant at Chemiepark Knapsack

matterr is establishing operations at Chemiepark Knapsack. The planned small-scale industrial depolymerisation plant will be located in the Hürth section of the site and will have an annual capacity of 10,000 tonnes. The facility marks an important step toward a fossil-free, circular PET industry. Groundbreaking is scheduled for 2026.

matterr welcomes BESTSELLER as new investor to scale polyester recycling

matterr, the German cleantech company pioneering polyester recycling, announces a strategic partnership with family-owned international fashion group BESTSELLER. The investment, made through BESTSELLER’s innovation and investment platform Invest FWD, follows a major EU commitment of 30 million euros in public support through the EFRE/JTF program in North Rhine-Westphalia. Together, these milestones lay the foundation for matterr’s first small-scale industrial plant and the subsequent international scale-up of its technology.

Ence and ShareTex begin initial testing of the ATENEA innovation project to promote textile recycling in Spain

Ence and ShareTex are making progress on the Atenea R&D project, which aims to develop a complete value chain for textile recycling in Spain. Specifically, the goal of the ATENEA project—which is funded by the Center for Technological Development and Innovation (CDTI)—is to connect all the necessary stages for the recovery of textile waste, from collection and management, through recycling and transformation into new raw materials, to their incorporation into new textile products.

DePoly Inaugurates its Showcase Plant in Monthey Switzerland

What if used plastic bottles, PET packaging material and polyester textiles could become raw materials just as high performing as virgin resources? That is the ambition of DePoly, a circular materials company based in Sion, Switzerland which inaugurated its Showcase Plant in Monthey on July 6th & 7th. The first depolymerization facility of its kind and scale in Switzerland, this industrial Showcase Plant represents a major milestone in the company's growth and its journey toward commercialization.

ReHubs elects new Board of Directors to lead the next phase of ReHubs’ strategy to recycle 2.7 million tonnes of textile waste annually by 2035

ReHubs has elected its new Board of Directors, marking an important milestone as the industry alliance continues to accelerate the industrial scale-up of textile-to-textile recycling across Europe. The election took place during the ReHubs Annual Event in Brussels on June 23rd, held alongside the Textile Recycling Expo and Future Fabrics Expo. The newly elected Board combines expertise from across the textile value chain, reflecting ReHubs' collaborative approach to solving the industry’s textile waste crises.

YKK develops concept EXCELLA® zipper tape using nonwoven fabric partially derived from used clothing

YKK Corporation has developed a concept version of its premium EXCELLA® zipper series made from nonwoven fabric sheets created by fiberizing used clothing and other textile materials. Based on a proposal by fashion designer Yuima Nakazato, this item was created as a result of collaboration between Nakazato, Seiko Epson Corporation and YKK. The concept zipper was incorporated as a material component for pieces in the newest YUIMA NAKAZATO Couture Collection, “INFERNO,” which was unveiled in Paris, France on July 8, 2026.

ALADIN paves the way for circular and demand-driven textile production in Europe

Textile production can be organized sustainably by utilizing short supply chains and preventing overproduction. This can already be achieved today by intelligently connecting and efficiently utilizing existing infrastructure. At the same time, production becomes circular when innovative technologies and materials are used that enable high-quality recycling. The ALADIN research project, launched in May 2026 and co-funded with five million euros under the EU Horizon Europe program, is creating the conditions for this.
