Storage and Management of PCB

Since 1972, when the manufacture of products using polychlorinated biphenyl (PCB) was discontinued in Japan, Toshiba Group has kept PCB and PCB-containing products under strict surveillance, controlled them, and reported their storage to the relevant authorities in accordance with the Waste Management and Public Cleansing Act and the Act on Special Measures concerning Promotion of Proper Treatment of PCB Wastes in Japan. In addition to meeting the prescribed storage standards, the Group makes doubly sure through the installation of dikes and double containers and other measures that they are stored appropriately.

Identifying environmental liabilities


Enforcement of the Act on Special Measures concerning Promotion of Proper Treatment of PCB Wastes, obliges PCB waste storage business operators to dispose of PCB wastes properly by March 2027. As of March 31, 2022 and 2023, Toshiba Group recorded environmental liabilities of approximately 14.8 billion yen and 13.5 billion yen respectively as PCB detoxification outsourcing expenses. These expenses were incurred in relation to the disposal of products containing PCB that were stored and managed in business and productions sites nationwide and their facilities. We will continue to grasp and disclose such information properly.
