Collaboration using the world's first new dissolution and separation recycling technology for the complete recycling of polystyrene.

FP Corporation DIC Corporation

In November 2020, DIC and FPCO announced plans to collaborate in the practical implementation of a closed-loop recycling system for polystyrene that maximizes the technologies, as well as the collection and recycling systems, of both companies. In this initiative, colored foamed trays will be recycled into new trays just like conventional white trays using a new dissolution and separation recycling technology, enabling a "tray-to-tray" recycling. Additionally, this effort aims to realize the closed-loop recycling that uses chemical recycling technology to recycle polystyrene to styrene monomer, which is the raw material for polystyrene.
