Teijin Ltd. Launches Proof-of-Concept Project for Recycled Polycarbonate Material Traceability

Teijin Ltd. has initiated a demonstration project utilizing the Digital Product Passport (DPP) technology from The Hague-based company Circularise B.V. to achieve traceable management of recycled polycarbonate (PC) resin throughout the supply chain. Through this project, Teijin aims to verify the feasibility of using the DPP as a solution to meet compliance requirements outlined in the draft of the EU's End-of-Life Vehicles (ELV) Directive.

The core objective of the DPP is to provide material purchasing companies with easily accessible and verifiable multi-dimensional data, including material origin, composition, environmental impact, and disposal recommendations. For this proof-of-concept, Teijin is using two types of raw materials: one is recycled polycarbonate resin sourced from end-of-life vehicle headlights, and the other is its Panlite CM series of environmentally friendly composite materials, which blend recycled polycarbonate resin with virgin polycarbonate resin. Leveraging the DPP, customers can accurately verify whether the materials originate from end-of-life vehicles, the percentage of recycled content, as well as various physical property parameters of the materials.

Teijin will collaborate with Circularise's Japanese subsidiary to simulate market circulation scenarios for both Panlite CM composite materials and headlight-derived recycled polycarbonate resin, thereby testing the practical application effectiveness of the DPP through scenario-based simulations. Based on the results of these simulated tests, Teijin plans to equip all its future recycled polycarbonate resin products with DPPs. The company is committed to establishing a comprehensive sustainable material data system covering the entire procurement process, providing clients who focus on green materials with quantifiable environmental performance indicators.

In fact, the Teijin Group has previously conducted traceability verification projects using DPPs for its recycled aramid fiber and recycled carbon fiber products.
