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.

To manage high-concentration PCB waste, Toshiba Group has registered some 2,500 transformers and condensers with Japan Environmental Storage & Safety Corporation (JESCO), which provides wide-area PCB treatment services, and is gradually disposing of these devices according to JESCO's plan.

Meanwhile, we are also working to dispose of low-concentration PCB waste at government-certified detoxification facilities and prefectural governor-authorized facilities (42 facilities across Japan as of the end of March 2018).

Transformers and condensers for which the possibility of containing PCB cannot be ruled out are in use at a number of production sites.

When checking transformers for maintenance, we analyze the oil, and if we discover PCB contained in such oil, we suspend use of the transformers, upgrade them, or draft a disposal plan. Condensers are fully sealed and become useless if their oil is analyzed, regardless of whether or not they contain PCB. Therefore, we are drafting plans to gradually update condensers while taking care not to impair our business activities. These measures are incorporated into Toshiba Group's disposal policies.

We will continue our efforts to dispose of devices that contain PCB properly by the legal processing deadline.

Disposal policies

  PCB waste (Pollution-confirmed materials for storage) PCB devices in use
High density Proceed with disposal according to JESCO’s disposal plan. Formulate plans to upgrade or dispose of devices.
Low density Proceed with disposal at government-certified facilities. Transformers: Analyze oil during maintenance. Formulate plans to upgrade or dispose of devices containing PCB.
Condensers: Formulate plans to gradually upgrade fully sealed devices while taking care not to impair business activities. Formulate plans to dispose of devices containing PCB.

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, 2017 and 2018, Toshiba Group recorded environmental liabilities of approximately 16.2 billion yen and 11.7 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.
