Environmentally friendly resin-coated steel sheet
Toyo Kohan Co., Ltd.
Decorative steel sheets used in home appliances and building materials have reduced greenhouse gas (GHG) emissions by replacing the raw material with recycled material (electric furnace material).
● Overcoming challenges unique to recycled materials and achieving high-quality mass production.
● Contributes to reducing GHG emissions across the entire supply chain.
To apply recycled materials to resin-coated steel sheets, it was necessary to meet the required properties for resin-coated steel sheets, such as adhesion between the film and the steel sheet and corrosion resistance of the product. These challenges were overcome through our unique chemical conversion processing technology and improvements in the quality of electric furnace-made base sheets, achieving both environmental performance and the high quality required for resin-coated steel sheets.
By using hot-dip galvanized steel sheets derived from recycled materials, we contribute not only to reducing our own Scope 3 emissions but also to reducing our customers' Scope 3 emissions. This product contributes to reducing GHG emissions throughout the entire supply chain.
*There are two methods for producing raw iron plates: the electric arc furnace method and the blast furnace method, which uses iron ore as raw material. The electric arc furnace method can reduce GHG emissions during the raw iron plate production process to about 1/4 to 1/5 of that of the blast furnace method.
Switching from blast furnace materials to electric furnace materials is a highly effective and important initiative for reducing GHG emissions.
This initiative is significant as the first step toward a major change, and I hope that it will be expanded throughout the company in the future, while also taking into consideration the increased costs associated with the shifts.
