Teijin showcased two proof-of-concept applications at JEC World 2025 in Paris, demonstrating : technology's critical role in verifying sustainability and the origin of recycled materials. Circularise’s solution enabled Teijin to substantiate these claims with accurate, secure, and verifiable data.

The first proof of concept focused on Teijin aramid pulp made by grinding aramid fibers from recycled materials. The : tracked its origins to discarded lifting slings manufactured by Hampidjan. The material used in the Terra® Sling was traced back to Twaron® filament yarn supplied by Teijin Aramid, illustrating a transparent and verifiable recycling process with the help of Circularise’s :.

The second proof of concept demonstrated how Circularise’s platform enables traceability for Tenax Next™ R2S P513 6mm, a short carbon fibre product manufactured from post-production waste of carbon fibre filament yarn. The Digital Product Passport clearly showcased the reintegration of specific waste streams back into the product.

Implementation of :s will follow a phased approach, with full adoption expected by 2030. By 2027, a basic : will be mandatory for textiles, chemical products and other items sold in the EU. This move positions Circularise as a vital technology provider for industries aiming to meet sustainability and regulatory compliance.

"Launching these :s with Teijin is a crucial step in realising our vision of a transparent and sustainable global supply chain," said Jordi De Vos, co-founder of Circularise. "We believe traceability is fundamental for sustainability, supply chain risk management, regulatory compliance, and consumer trust. This project highlights how our technology empowers companies to achieve their sustainability goals and aligns with broader regulatory requirements."
