[Keynote Address] Resource Circulation of PA6 Resin with Subcritical Water Method

Hideki Matsumoto･Koya Kato･Tsuyoshi Tominaga (Toray Industries)

Current status, issues, and future prospects of research and development on resource recycling of PA6 resin by the subcritical water method, using market recovered products as raw material.

Utilization of Post-Consumer Recycled Resources for Development High-Performance Engineering Plastics

Shuta Iseki･Hidekazu Shoji･Yasushi Yamanaka (Mitsubishi Chemical)

To achieve circular economy, there are growing attention for utilization of recycled resources in mobility applications. On the other hand, progress of “CASE” requires plastic materials to be multi-functionalized and high-performance. In this presentation, we suggest the design of engineering-plastic materials for both combining utilization of post-consumer recycled resources and functionalization.

Establishment of Recycling of Self-Sufficient PET Bottle for Seat Skin Material
-Supply Environmental-Friendly Material for Vehicles by Their Own Company's Employees-

Naoki Oshita (Toyota Motor)

We have established the world's first recycling system for Self-sufficient PET Bottle collected in TOYOTA into our own products, allowing us to mass produce seat fabric from PET bottles.
In order to achieve that, we establish internal collecting system by our own employees, and also new circular supply chain with related companies.
