Measures to develop a resource recycling-based society

Basic approach

In addition to complying with laws and regulations, as a member of the global community, we take the environment into consideration and actively promote activities from the perspective of the "4 Rs" (Reduce, Reuse, Recycle, and Renewable).

We are a resource-recycling corporation in the sense that our manufacturing uses steel scrap as a raw material. We are fully focused on our mission of helping to recycle resources through our businesses and minimizing and recycling by-products.

To ensure the safe, secure and stable handling of by-products, we are working to establish a number of different recycling techniques and recyclers, while developing new technologies and recycled material users.

FY2020 targets and results

As in the previous year, we have continued to promote recycling and reduce the amount of waste generated by complying with the Aichi Prefecture Ordinance "Guidelines for the Proper Use of Recycled Resources. Although the remaining target materials were considered difficult to recycle technically and in terms of cost, we successfully reduced indirect landfill waste by starting to collect and recycle zinc from cleaning dust. As a result, we recycled 99.1% of the by-products.
In fiscal 2021, our goal is again to achieve zero emissions.

Contributions to end-of-life car recycling

In line with the End-of-Life Vehicle Recycling Law, which came into force in 2005, the Toyota Group is working to achieve complete recycling.

Aichi Steel is working with Toyota Metal Co., Ltd. to improve recycling, and we are recycling automobile shredder residue (ASR)* by melting “dallied solids” and “solids balers” in the electric furnace as raw material.

* Automobile shredder residue (ASR):
All remaining waste after crushing end-of-life vehicles in an industrial shredder and removing ferrous and non-ferrous metals.
