Development of Circular Materials Based on Network Polymers with Dynamic Crosslinking Structures:
Social Implementation of a Carbon-Fiber Recycling Circulation System Utilizing Self-Healing Functional Materials

Collaborating Organization

Teijin Limited

Research and Development Overview

In FY2026, building on carbon-fiber recycling technology, the work will center on demonstration trials aimed at social implementation. Through these demonstrations, the technology readiness level will be raised, while a framework will be developed to make the environmental value of recycled materials visible across the entire value chain.

Focus Areas

In addition, for social implementation, a blockchain platform connecting the stages of (1) material manufacturers → (2) processing manufacturers → (3) product manufacturers → (4) disposal/collection operators → (5) recyclers will be utilized to build a mechanism for sharing GHG emissions, emission certificates, traceability information, and digital certificates among stakeholders. This will visualize the environmental value of recycled materials and promote arterial–venous (forward–reverse logistics) collaboration, leading to the social implementation of a circular economy.

The blockchain platform connects 1 material manufacturers, 2 processing manufacturers, 3 product manufacturers, 4 waste collection contractors, and 5 recyclers, enabling the sharing of GHG emissions data, certificates, and traceability information throughout the value chain.
