Recovery and Reuse of Auto Parts from End-of-Life Vehicles

Tokio Marine Holdings, Inc.

When an automobile accident happens and its insurance company pay the claim in full amount of the automobile insurance, the ownership of the vehicle is transferred from the insurance policyholder to the insurance company.

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.

Regarding the Use of Recycled Plastic

TOTO. LTD

As part of our initiative to promote the 3Rs (Reduce, Reuse, Recycle) in our products, we are actively utilizing recycled plastic. In Japan, we use over 100 tons of recycled plastic each month. The main application is in the tank part of toilets, where over 80% is comprised of recycled plastic.

closed recycling system of label backing release liner" Resource Recycling Project"

Resource Recycling Project NEION Film Coatings Corp． TOYOBO CO., LTD. Shionogi Pharma Co., Ltd.

label backing release liner typically uses composite materials of paper and 　 resin, which　are generally difficult to recycle. As a result, they become a large amount of industrial waste and are incinerated. In this project, we replace these label backing release liner with release liner for recycling made from PET-based synthetic paper. After use, the release paper is collected as valuable materials and subjected to material recycling. By using the recycled material again as a raw material for release liner for recycling, we achieve Film-to-Film recycling. This will enable the social implementation of closed recycling system of label backing release liner.

Educative activities to promote closed-loop recycling of PET bottles in collaboration with companies and an industry association

Japan Soft Drink Association Japan Airport Terminal Co.,Ltd. Tokyo International Air Terminal Corporation

The collection of PET bottles can be broadly categorized into 'Households related route collection', where they are discharged from homes, and 'Business related route collection', where they are collected from offices, factories and next to vending machines. PET bottles collected from households are easily recycled by sorting them into three parts segregation recycling (caps, labels and bottles), while bottles collected by 'Business related route' are often contaminated with foreign particles and not sorted into three parts segregation.
