Toyoda Gosei to Soar Recycling Grit in its Japan Line

Toyoda Gosei Co., Ltd. is doubling its rubber recycling capacity at the Morimachi Plant in central Japan. Specifically, it aims to accelerate the recycling of rubber used in automobiles.
While progress is ongoing in the recycling of resources such as steel and plastic in the automobile industry, the recycling of rubber products is difficult. In fact, almost all rubber waste needs to undergo incineration.

Incorporates Improved Technology

Toyoda Gosei began its first recycling line in FY2021, using its proprietary devulcanization technology. Moreover, it can recycle rubber products into high-quality raw materials. The company has been reusing the waste material generated in the production of products.

Background for increased rubber recycling

The company is already preparing the operation of its second line. Thus, doubling the previous rubber recycling capacity to 1,200 tons annually.

A second line is now being put into operation that will double the previous rubber recycling capacity to 1,200 tons annually. The new line, which will start mass production in FY2025, incorporates improved technology to raise the quality of the recycled rubber.

This enables the company to increase the percentage of recycled material mixed into new material from several percent up to 20 percent. Particularly, this is almost recycling all of the waste from opening trim weatherstrips* manufactured at the Morimachi Plant.

Steps in expanding rubber recycling

The recycled rubber will also be of use in other products using the same type of synthetic rubber (ethylene propylene diene monomer; EPDM) as the waste material. Technical development including recycling natural rubber is also underway today. Moreover, the company aims to further establish a recycling system that recovers rubber from end-of-life vehicles. Going forward, Toyoda Gosei will collaborate with automakers and other entities to lead the world in rubber recycling.
