B1-01 Development on a construction waste plastic recycle process with collaboration between arterial and venous industries for the circular economy.
Principal Investigator
Toshiaki Yoshioka (Tohoku University)
Research Overview
The purpose of this R&D is to maximize the carbon and chlorine circulation of the 590,000 tons of construction waste plastics emitted annually and contribute a circular economy system. The recycling rate of construction waste plastics is estimated to be 80% by volume basis, but most of it is thermal recycling by incineration power generation, and in light of the international trend toward plastic recycling, there is an urgent need to establish a recycling method that enables circulation to arterial industries.
Development Goals
- Development on a sorting method to increase the recycling rate of a construction waste plastic
- Optimization of a gasification process and operation
- Life cycle assessment of a construction waste plastic recycle process
- Evolution of a manifest for industrial waste such as Digital Product Passport (DPP) and Digital Material Passport (DMP)
