We deliver a technology that revolutionizes today's PET recycling by being scalable, economically viable, and environmentally responsible.
We are driving polyester beyond fossil fuels. By transforming packaging and textile waste into virgin-quality drop-in feedstocks, we enable high-performance materials to return to production continuously. Our depolymerisation technology combines proven recovery rates with scalable design — turning today’s waste into tomorrow’s resources. A new chapter of circular industry begins, ready to expand worldwide.
We leverage the power of depolymerization to unlock the full value of PET waste. Our technology transforms complex, mixed PET waste streams—including polyester blended textiles and multilayer packaging—into high-quality raw materials, ready for reuse. By breaking PET down to its molecular building blocks, we regenerate virgin-quality, drop-in-ready materials and enable true circularity. We eliminate fossil dependency for PET and close the loop—for packaging, textiles, and the planet. That’s how we build the future—by breaking down the past.

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 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.
We offer a solution for PET-rich waste streams that cannot be mechanically recycled—including complex packaging and textiles. With just 80% polyester content, we turn waste into valuable monomers instead of sending it to incineration. Let’s talk about your toughest waste streams—we’re ready to turn them into resources.
matterr delivers monomers in virgin quality—seamlessly compatible with today’s PET production processes. No process changes. No compromises. With our high-purity recycled materials, you can produce circular PET on an industrial scale and future-proof your business for a low-carbon economy.
We power truly sustainable supply chains—by turning PET waste into virgin-quality material. Our technology enables circularity even for complex, multi-material products, whether post-consumer or post-industrial. We want you to keep using polyester freely—blended, layered, or otherwise—without trade-offs in performance, design, or sustainability. This is circularity at scale.
This operation benefits from support from the ERDF/JTF program in North Rhine-Westphalia.
