Osaka PCB Waste Treatment Facility
Osaka Facility is the fourth regional PCB waste treatment facility
in Japan, thanks to the acceptance of the facility by Osaka City.
JESCO started construction in January 2005, and after a test run conducted from March to August 2006,
full operations started on October 3, 2006.

|C Region:||Gifu, Shizuoka, Aichi and Mie Prefecture|
|E Region:||Hokkaido, Aomori, Iwate, Miyagi, Akita, Yamagata, Fukushima, Ibaraki, Tochigi, Gunma, Niigata, Toyama, Ishikawa, Fukui, Yamanashi and Nagano Prefecture|
- Pre-treatment of containers and components: Solvent Cleansing Method and Vacuum Heating Separationt Method
PCB decomposition: Dechlorination Method
Overview of West Wing
5-story steel framed building, Height: 30 m, Total floor area: 17,600 m2
Overview of East Wing
5-story steel framed building, Height: 27 m, Total floor area: 7,650 m2
Osaka Waste Treatment Facility is divided into the West Wing and the East Wing.
In the West Wing, PCB is extracted from transformers and capacitors and the containers are disassembled
into the shape and size suitable for treatment. The methods used to collect PCB from the containers
are the "Solvent Cleansing Method" and the "Vacuum Heating Separation Method".
In the East Wing, the collected PCB is chemically decomposed using the "Catalyst Hydrogenation Dechlorination Method".

Safety Measures of Osaka Facility
||Operations are monitored 24 hours a day by computers from the Central Monitoring Room.
|Measures for Exhaust
||Exhaust from process is cleaned by oil scrubbers in the exhaust treatment equipment, and goes
through activated carbon as a safety net before released. Furthermore,
the air pressure inside the facilities are kept lower than atmosphere outside, to keep air from
|Measures to Prevent Leakage
||To prevent PCB from leaving the facilities, oil pans are set under PCB-handling areas and PCB
treatment equipment. Floors are coated with epoxy resin which is impermeable, chemical resistant,
and wear-resistant. These measures will prevent PCB from penetrating floors in case of
a spilling. The oil pans and floors are equipped with detectors to identify leakage.
||When an earthquake above preset intensity is detected, facilities are shut down automatically.
Also, to protect facilities from fire, automatic fire alarms, chemical fire extinguishers and fire
hydrants are installed.
Information Disclosure of Operation Status
JESCO makes effort to actively disclose information from planning of facilities to operation status.
