Idemitsu and Partners Develop Recycled Plastic Building Material for Japan's Construction Sector
Idemitsu Kosan, Takenaka, and three partners have created a recycled plastic from post-consumer waste for construction applications. This initiative aims to enhance circular-economy practices in Japan's construction industry, although no production metrics or rollout timelines have been disclosed.

Idemitsu Kosan, Takenaka, and partners have successfully produced recycled plastic from post-consumer waste, applying it to construction materials. This project employs chemical recycling and a mass-balance approach, where materials are processed with both recycled and conventional feedstocks.
The resulting post-consumer recycled plastic has quality comparable to fossil fuel-derived plastics. Fukubi Chemical Industry utilized this recycled material in its Free Floor CP dry sound-insulating double-floor system.
The partners aim to expand recycling efforts for construction site waste, although details regarding production capacity and commercial timelines remain unspecified. The construction sector's potential for circular-economy initiatives depends on consistent material quality and performance compliance.
