The Sumitomo Metals Group conserves the environment through technology. Resolving air pollution at Besshi Copper Mine some 70 years ago has become Sumitomo’s heritage. We have developed new technology to reduce CO2 emissions from our manufacturing processes and new products that help curb emissions by our customers. Our researchers are trying to invent totally revolutionary steelmaking methods that dramatically decrease environmental impact. We also transfer environmental technologies overseas to help the global steel industry become more eco-friendly.
