Engaging in the design, construction and maintenance of PCB* detoxification treatment facilities, we are taking on the ongoing challenge of ensuring a future society completely free of this harmful legacy.
* Polychlorinated biphenyl: a colorless transparent chemical, chemical substance in an oily liquid form. PCB was once extensively used in various applications, including as insulating oil for use in electrical devices, as it has chemically stable properties, for example, being difficult to dissolve in water and providing high electrical insulation. However, the manufacture of PCB is currently banned as it was found to be deleterious to human health. Today, businesses are obliged to maintain the proper management of and report the existence of any waste in their possession containing PCB. It is legally mandated to be safely disposed of by March 31, 2027.
We have a technology for chemically decomposing liquid PCB recovered from such devices as condensers and transformers. This technology is used at government-sponsored collective disposal facilities in Japan as well as at private disposal facilities run by domestic corporations.
Even after the majority of the PCB content is recovered from transformers and condensers, there are often traces left on the surface of components that needs to be completely removed. This technology removes remaining PCB and it is used at government-sponsored collective disposal facilities in Japan.
This technology is capable of collectively treating PCB-containing waste that comes in a variety of shapes and characteristics, such as fluorescent lamp ballasts and other PCB-contaminated electrical components with complex shapes as well as sludge, waste cloth and pressure sensitive copying paper containing PCB. This technology is used at government-sponsored collective disposal facilities in Japan.
