Management of Chemical Substances and Reduction of Hazardous Substances

Management of PCBs, CFCs, etc.

Controlling PCBs

In accordance with the Law concerning Special Measures for Promotion of Proper Treatment of PCB Wastes, at our refineries and complexes, we appropriately store and manage oil containing polychlorinated biphenyls (PCBs) as well as transformers and other equipment that contain these substances. Under the same law and the national Basic Plan for PCB Waste Treatment, final deadlines have been set for the completion of the treatment of all PCB waste and, accordingly, we are steadily carrying out the processing of such waste.

Managing Fluorocarbons

In accordance with the Act for Rational Use and Proper Management of Fluorocarbons, which came into effect on April 1, 2020, we have been implementing steps to prevent the leakage of fluorocarbons. We are also considering timing the replacement of large process equipment that uses HCFCs, which have strong ozone depleting effects, to coincide with periodic shutdown maintenance at our refineries and plants.
