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 refineries and complexes, we appropriately store and manage oil containing polychlorinated biphenyls (PCBs) as well as transformers or 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 CFCs

In accordance with the Act for Rational Use and Proper Management of Fluorocarbons, which came into effect on April 1, 2015, we have been implementing steps to prevent the leakage of fluorocarbons. The Safety, Environment (HSSE) & Quality Assurance Department undertakes annual inspections on the progress of changeover to non-fluorocarbon coolants at our facilities. As our refineries and complexes house a significant portion of our large-scale processing equipment containing CFCs and HCFCs, which damage the ozone layer, we have been replacing these equipment during the performance of major shutdown maintenance, aiming to eliminate the use of CFCs and HCFCs by March 2026.
