Teijin has started rolling out initiatives to enable aramid and carbon fibres to be accompanied by Digital Product Passport (DPP) technology to enhancse supply chain transparency by verifying the origins of materials and supporting sustainability claims.

The company is using the supply chain traceability system of Netherlands-based Circularise, in which it has invested since November 2024, to develop DPPs for each product.

The implementation of DPPs is being mandated by Europe’s Ecodesign for Sustainable Products Regulation (ESPR). At JEC World 2025 in Paris, Teijin presented two proof-of-concept applications highlighting how DPPs enhance traceability and circularity in recycled materials use.

The ESPR, which came into force in July 2024, aims to “significantly improve the sustainability of products placed on the EU market by improving their circularity, energy performance, recyclability and durability,” according to the European Commission. Implementation of DPPs will follow a phased approach, with full adoption expected by 2030. From 2027, a DPP will be mandatory for all industrial and electric vehicle batteries and in the future, it is expected that a basic DPP will also be mandatory for textiles and other products.

The first DPP demonstrated at JEC was for aramid pulp made by grinding aramid fibres from recycled materials. The DPP shows the pathway of the aramid fibres from their origins to the customer Hampidjan, the producer of the Terra Sling. Teijin is now able to fully trace the discarded slings up to their return to be used again for the production of aramid pulp.

The second DPP showcased the traceability of Tenax Next R2S P513 6mm, a short carbon fibre product. This material is produced using post-production waste from carbon fibre filament yarn manufacturing. The DPP demonstrates how specific waste streams are reintegrated into new product.
