Resource Recycling
Basic Concept
Iron is a material with exceptional recyclability. We use steel scrap as raw material, melt it in an electric furnace to remove impurities, refine it into crude steel, and then roll it to produce steel products. We will contribute to the realization of a sustainable society by enhancing and expanding systems that facilitate efficient recycling of steel scrap and realizing a sound material-cycle society (circular economy).

The Challenge to Achieve Zero Waste (Zero Emissions)
Our Group reuses used steel scrap as the main raw material and recycles waste materials such as slag, dust, scale and other waste generated in the manufacturing process. Some of the slag generated in the steelmaking process at Yamato Steel is crushed and aged in-house and sold to recycling companies as valuable resources.
In FY2023, we promoted waste reduction by implementing intermediate treatment of industrial waste and converting it into recyclable products, improving the recycling rate by 4.3% compared to FY2020. We are steadily working toward our mid-term target of a 5% increase in the industrial waste recycling rate.
About the management of slag and slag products, we are striving for the proper management of steel slag products by preparing and complying with a management manual following the "Guidelines for the Management of Iron and Steel Slag Products" established by the Nippon Slag Association.
