Initiatives to Address PCB Pollution
Facilitating the proper management of PCB waste and full-scale measures for soil remediation
Panasonic discontinued the production of equipment containing polychlorinated biphenyls (PCBs) in 1972 and has since been strictly managing its PCB wastes. As for the PCB-containing capacitors buried at five of our factories, which we voluntarily made public in January 2003, we completed the excavation at the end of March 2009. We also began treatment of the contaminated soil on a full scale in September 2007, commissioning its treatment to Geosteam Corporation, which has PCB contaminated soil purification facilities in Kitakyushu, Japan. By the end of March 2009, about 1,640 tons of the contaminated soil was transported to and treated at the facilities.
Numbers of PCB-containing items registered with JESCO*1 and those already decontaminated (as of March 31, 2009)
| Type of waste | Registered with JESCO | Already decontaminated |
|---|---|---|
| Transformers, capacitors, etc. | 2,023 devices*2 | 824 devices |
| PCB and PCB-containing oil | About 4,700 kg | – |
- *1 Japan Environmental Safety Corporation (company engaged in PCB waste treatment).
- *2 In and after 2008, a total of four devices were founded to be outside the scope.
