Mitsubishi Chemical aims to commercialize the world's first chemical recycling of PC resin
The Mitsubishi Chemical Group (the MCG Group) has started a study aimed at realizing a processing capacity of approximately 10,000 tons per year by 2030, seeking to commercialize the world's first chemical recycling by depolymerization of polycarbonate resin (PC resin).
A bench facility for a verification study is currently under construction at the Fukuoka Plant, with completion scheduled for August 2023. The MCG Group plans to complete demonstration experiments during the same fiscal year and then proceed with specific commercialization studies.
The demonstration project has been adopted as a subsidized project for the Ministry of the Environment's "FY2022 Demonstration Project for a Plastic Resource Circulation System toward a Decarbonized Society" program.
Chemically recycled PC resin.
Currently, it is common to recycle used PC resin through mechanical recycling. There is a problem of not being able to obtain recycled resin of sufficient quality if degraded or different resins are mixed in.
In contrast, chemical recycling, in which used PC resin is depolymerized, returned to monomers, and then polymerized again, makes it possible to recycle a wider range of used PC resin into high-quality recycled PC resin.
The MCG Group aims not only to establish chemical recycling technology, but to build a recycling system for used PC resin. It plans to actively cooperate with companies that use PC resin in their products.
