Appropriate Management of Chemical Substances

The Kobe Steel Group carries out thorough and appropriate management of chemical substances, in line with domestic and international standards, and endeavors to reduce the use of hazardous substances and replace such substances with safer alternatives.

Thorough Chemical Substance Management

Kobe Steel has established the Kobe Steel Group Policy on Controlling Hazardous Chemical Substances and pursues thorough chemical substance management.

The use and management of each substance is clarified through Designated Chemical Substance Management Sheets. In addition to tallying transfer and output of substances as required by the PRTR Law1, we also engage in initiatives to limit the use and output of such substances.

According to reported figures collected under the PRTR Law for each location in the Kobe Steel Group (in Japan), the Kobe Steel Group handled 51 substances, with a total output2 of approximately 816 tons, and total transfer3 of 553 tons.

Management of Waste Electrical Equipment Containing PCB

Transformers, condensers and other used equipment containing PCB (polychlorinated biphenyl) are handled at a special depository, as prescribed under the PCB Special Measures Law.

When contracting for outside disposal, we visit sites directly and train persons-in-charge in proper management rules. Oversight is also carried out by the Environmental Control & Disaster Prevention Department.
