Acceleration of recycling waste plastics from small household appliances: Establishing large-scale collection routes and an integrated resource circulation process through advanced sorting technologies

Mitsubishi Electric Corporation Future Ecology Co., Ltd. BIC CAMERA Inc. Veolia Japan GK digglue.Inc

Currently, the recycling of used small electronic devices aims to sort and recover metals with high resource value, such as iron, aluminum, and copper. As a result, the recycling rate of waste plastics from small household appliance is lower compared to the waste plastics recovered from the four items specified by the Household Appliance Recycling Law (refrigerators, air conditioners, washing machines, and televisions). Approximately 80% of these waste plastics are processed through thermal recycling, which reuses the heat generated from combustion as energy.

Building the circulation-based model throughout the product life cycle by realizing and commercializing the recycling system of used disposable diaper

Unicharm Corporation Shibushi City,Kagoshima Prefecture Osaki Town, Soo District, Kagoshima Prefecture SORECYCLECENTER

In May 2016, Unicharm has joined the "Used Disposable Diaper Recycling Promotional Council" composed of 18 groups and individuals with an initiative of City of Shibushi, Kagoshima, and, on November 1, 2016, we entered into a three-way agreement with City of Shibushi and So Recycle Center on collection and recycling of used disposable diaper (The agreement was then expanded to four-way on April 2, 2018, as Osaki Town joined us.).

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.
