Oono Associates PCB Waste Treatment

Japan’s largest storage facility

We have developed a seamless system for treating low-concentration PCB waste from initial analysis to final disposal. We offer speedy and reliable analysis and treatment, making life easier for storage facility operators, keeping environmental burdens to the minimum, and providing a service (as waste treatment specialists) to the whole community.

Third authorization from the Minister for the Environment

On March 30, 2018, we received our third authorization for low-concentration PCB waste treatment from the Minister for the Environment

We have constructed Japan’s largest storage facility for PCB waste treatment, enabling us to accept orders without delay. At this facility equipped with overhead cranes and dedicated fork lift trucks, we can accommodate waste transport vehicles safely and reliably. Also, in case leaks or other accidents occur, the entire floor area has an impermeable epoxy coating, and for absolutely secure storage the facility is surrounded by a drainage gutter.
