JESCO will establish five regional plants nationwide.
Kitakyushu Facility was the first to be completed and started operations in Dec. 2004.
Toyota Facility, and Tokyo Facility started operations in 2005, and Osaka Facility started in 2006,
and Hokkaido Facility started operations in 2008.
Each facility is assigned by the government to treat PCB wastes of regions shown below.

Treatment Methods
All JESCO facilities use only chemical decomposition methods, because they do not produce combustion gases. Tokyo Facility adopts the "hydrothermal oxidation decomposition method", and the other four facilities adopt the "dechlorination method".
In accordance with the company policy to carry out PCB waste treatment with priority on safe and reliable treatment, JESCO designs its facilities conforming to the concepts of adopting safe and sure treatment methods.
When determining treatment method for each facility, experts at the JESCO PCB Waste Treatment Project Exploratory Committee discuss necessary requirements for the facility, considering terms such as types of PCB wastes to treat and geographical constraints. In accordance with the conclusion of Committee discussions, JESCO invites public proposals on concrete treatment methods under WTO bidding rules, and carefully examines proposals from technical aspects and implementation aspects, and finally makes decision on which method to adopt.

Safety Measures Given Highest Priority
JESCO has set up "the PCB Waste Treatment Exploratory Committee", composed of outside specialists.
JESCO receives guidance and advice on technology, environmental and safety measures, safety design, management of safety and health of workers, etc.
[Basic Concept of JESCO's Facilities]
Adoption of Safe and Reliable PCB Treatment Method
Treatment methods and other matters are examined by experts in "the PCB Waste Treatment Exploratory Committee".
Multiple Safety Measures for Risk Management
JESCO gives its highest priority to safety, and takes all possible measures to ensure it.
All facilities and equipment are designed so that processes are safe,
and are fully equipped with operation monitoring systems. "Fail-safe" functions prevent
malpractice or human errors, while multiple protective structures with "Safety Net" functions prevent damage to spread.
Facilities are designed to withstand not only incidents that may occur during normal operation,
but also unavoidable disasters such as earthquakes and typhoons, and in all cases operations are to shut down safely to minimize
affect to the environment.
Information Disclosure of Operation Status
JESCO makes effort to actively disclose information from planning of facilities to operation status.
