With mounting pressure on the fashion industry to prove—not just promise—circularity, fibre innovation is undergoing a reset. It’s no longer enough to be recycled. Brands, consumers, and regulators are asking: Can these materials go around again? Are they compatible with real systems of reuse and regeneration?

RE&UP, Principal Sponsor of Global Fashion Summit: Copenhagen Edition 2025, has answered this call with an industry-first validation. The company reported that it recently became the first fibre manufacturer in the world to achieve Cradle to Cradle Certified® for Product Circularity —one of the most rigorous global benchmarks for circular product design.

Three RE&UP products—Next-Gen Recycled Cotton (pre- and post-consumer) and Textile-to-Textile Recycled Polyester Chips—have been certified at Platinum and Silver levels, respectively. This distinction goes far beyond recycled content; it verifies that these materials are fully compatible with safe, scalable, and repeatable cycling systems.

For a company already operating at industrial scale, with 80,000 tonnes of annual processing capacity, RE&UP heralded that their fibres aren’t just circular in theory—they’re circular in practice. The materials are already being used in garments by global fashion brands, backed by traceability, performance, and infrastructure.

Ebru Ozkucuk Guler, Chief Sustainability Officer, RE&UP, said:

“For too long, circularity has been more of a buzzword than a reality. With this certification, we’re proving that RE&UP’s next-gen fibres can meet, and exceed, the highest industry standards. This is what credible, scalable circularity looks like, and it’s already on the market.”

As fibre regulation tightens and textile waste targets grow closer, RE&UP’s milestone offers more than a badge—it provides a model where innovation is grounded in evidence, and scale is grounded in action.
