Measures to develop a recycling-based society
In addition to complying with laws and regulations, we are looking after the environment and actively promoting 3R activities (reduce, reuse, recycle) as fellow inhabitants of this planet.
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.
FY2019 targets and results
As in fiscal 2018, in fiscal 2019 we continued both to comply with the Aichi Prefecture ordinance on Appropriate Use of Recycled Resources, and to promote waste recycling and waste volume reductions. In fiscal 2019, we recycled 99.1% of the byproducts we produced. However, in fiscal 2020, our goal is again to achieve zero emissions.
While it is difficult to recycle byproducts from a technological perspective, in fiscal 2019 we continued to recycle waste refractory materials as secondary materials in electric furnaces. In fiscal 2020, we will also recover zinc from dust collected during cleaning processes and reduce the remaining amount of waste that goes to landfill.
Contributions to end-of-life car recycling
In accordance with the End-of-Life Car Recycling Act, which came into effect in 2005, the Toyota Group has been working towards total recycling. Aichi Steel is cooperating with Toyota Metal Co., Ltd. to improve recycling and develop recycling technology for glass parts, which have been the most difficult.
We introduced silica sand into steel making slag generated in electric furnaces as a molten slag cooling down material*, but we focused on the similarities between silica sand and the glass components and made it possible to achieve the same effects by mixing silica sand with waste glass, and it is now possible to recycle waste glass as a car recycling sub-material.As a result, the end-of-life car recycling rate increased to 99.8%.
* Molten slag cooling down material: A car recycling sub-material that is added to control the slag components, reduce the temperature as a cooling material, and curtail explosive boiling.
Waste glass from cars was previously difficult to recycle due to its specialty components and color
