Tokyo, December 20, 2011 ― Kawasaki Heavy Industries, Ltd. announced today that it has been awarded a contract from the city of Miyakonojo, Miyazaki Prefecture for a project to build and maintain its Clean Center following approval of the city council. The design-build-maintain project ordered by the city includes the construction of a waste treatment facility and its maintenance over a 20-year period.

The facility to be built under the project will be able to process 230 tons of waste per day using two incinerators. Also, a range of anti-air pollution measures will be put in place for a smaller environmental impact. This includes the use of parallel flow stoker incinerators capable of high-temperature combustion at low excess air ratio. Flue gas exiting the incinerators will be treated with bag filters, a selective catalytic reduction device, and a flue gas recirculation system.

This facility combines high-temperature, high-pressure boilers and an extraction turbine with the incinerators for superior environmental and energy-saving performance. Delivering a maximum power generation capacity of 4,990 kW, the facility boasts a generating efficiency of 20% at normal waste treatment operation. This high efficiency rate adds up to fewer greenhouse gas emissions, while generating enough electricity to run the facility with a surplus that can be sold to the local power grid.

The architectural design of the facility also emphasizes harmony with the natural environment, its exterior blending harmoniously with the surrounding mountain ranges.

A special purpose company, Green Park Miyakonojo Co., Ltd., will be established for the maintenance operation. The facility will be run with a focus on the community and a sound operation that contributes to the municipal waste treatment.

Kawasaki has a wide range of incineration technologies in addition to its stoker-type incinerator. Kawasaki will continue to develop new waste treatment technologies and market products that address diversifying environmental needs.
