Environmental Efforts in Corporate Activities

The Metal One Group proactively promotes effective resource use and recycling through our business activities in the pursuit of a recycling-oriented society. As a corporate group whose core businesses are the sale and processing of steel products, we are expanding the use of environmentally friendly steel products. Steel is a recycling-oriented material that can be used over and over again, contributing significantly to the effective use of resources.

The Metal One Group is also one of the largest handlers of steel scrap and stainless steel scrap in Japan, playing a vital role in creating a resource-recycling society. We supply steel materials used in renewable energy facilities such as solar and wind power generation, and foster a society that conserves resources and energy by promoting the adoption of high-performance steel products from steel manufacturers, including lightweight, high-strength products.
