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 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 7,400 transformers and condensers as well as some 73,000 stabilizers and compact condensers with Japan Environmental Storage & Safety Corporation (JESCO), which provides wide-area PCB treatment services, and is gradually disposing of the devices according to JESCO's plan.

We are also working to dispose of low-concentration PCB waste at government- certified detoxification facilities and prefectural governorauthorized facilities (31 facilities across Japan as of August 18, 2016).

During FY2016A, we also conducted a large-scale in-house survey on devices in use (including transformers, condensers, and stabilizers) that may contain PCB. As a result, we discovered devices that may contain PCB in use at a number of business and manufacturing 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 policies for the future and shared by all company personnel. We will continue our efforts to identify devices that contain PCB and to dispose of them properly.

Disposal policies for the future
  PCB waste (Pollution-confirmed materials for storage) PCB devices in use
High density Proceed 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 upgrade or dispose of devices containing PCB.
