Kawasaki Awarded Contract to Design Hokkaido PCB Waste Treatment Facility Addition

Mar. 27, 2008

Tokyo, March 27, 2008 — Kawasaki Plant Systems, Ltd. announced today that it has been awarded a contract by the Japan Environmental Safety Corporation (JESCO) to design an addition to JESCO’s Hokkaido PCB Waste Treatment Facility which is currently under construction in Muroran. Kawasaki’s contract, which is valued at approximately 2.4 billion yen, is part of a 26.2 billion yen project for designing and constructing the expanded facility. Kawasaki expects to receive an official order for the remaining part of the project by the end of March 2009.

Once that official order comes through, Kawasaki will employ Plasma Enhanced MelterTM (PEM) technology to design, construct and test the entire PCB (polychlorinated biphenyl) treatment system, from receiving/storage, pretreatment/shipping to utilities and ancillary facilities. The overall construction is scheduled for completion in August 2010.

The PCB treatment system has a number of technical and safety features designed for the safe decomposition of PCB.

1. PCB waste which is fed from the top of the PEMTM system is melted in a 3,000°C to 5,000°C plasma arc. The PCB waste is then melted into the molten glass bath which is maintained at over 1,400°C inside the process chamber. PCBs are thermally decomposed during this process and completely detoxified. The waste residue in the molten glass bath is recovered as leach-resistant*1 solidified molten glass and metal on the bottom of the chamber.

2. A negative pressure is maintained in all areas where PCBs exist. Exhaust gases are purified by the exhaust gas treatment system, which is constantly monitored for any malfunction. The system is also equipped with active carbon filters and emergency dampers in order to safeguard against PCB leaks into the environment outside the facility.

3. Exhaust gases from the PEMTM system are also constantly monitored and purified by active carbon filters before being released into the atmosphere. All secondary pollutants generated during the treatment process, including protective gear, are fed into the PEMTM system to be completely detoxified.

*1. A state in which soluble components do not dissolve out.
