Kobe Steel also proactively implements power generation that utilizes waste heat. Combined yy易游体育官网th the power generated from byproduct gases, over 60 percent of the power required by production processes is generated through energy recovery.

Insofar as possible, byproducts produced during production processes, such as steel slag**, dust and sludge, are also turned to effective use as raw materials in applications such as cement and roadbeds.
