Tokyo, May 21, 2020 — Kawasaki Heavy Industries, Ltd. announced today that it has been awarded a contract by the Kodaira, Murayama, Yamato Hygiene Association (Tokyo) for the New Waste Treatment Facility Construction and Operation Project (tentative name). It will be a DBO (design-build-operate) project in which Kawasaki will demolish and remove existing facilities,design and build new waste incineration and processing facilities, operate the new incineration facilities for 20 years and 6 months, and operate the non-combustible and bulky waste processing facilities for 24 years.

During this scrap-and-build project planned for execution in phases, Kawasaki will demolish two waste incineration facilities and a bulky waste processing facility situated in a very limited space adjacent to a quiet residential neighborhood, then proceed to build the new waste incineration facilities. All demolition and building work will be completed by the end of FY 2027. Kawasaki has secured the agreement and understanding of the local municipal governments that form the Kodaira. Murayama, Yamato Hygiene Association, along with other members of the community for this project, and will ensure the provision of sufficient waste treatment services during the project period while giving top priority to issues such as safety and environmental considerations.

The new waste incineration facilities will be capable of treating 236 tons of waste per day using two incinerators, each with a capacity of 118 tons every 24 hours. Incineration facilities will come equipped with leading-edge Smart-ACC®* technology and use Kawasaki's proprietary parallel-flow incinerator configuration. Each of the incinerators will combine high-temperature, high-pressure boilers and extraction condensing steam turbines for high-efficiency electric power generation that supplies all the electricity the facility needs. In addition, surplus power will be sold in quantities sufficient to supply approximately 8,100 general households annually. The facilities will feature architectural design that harmonizes with nearby sites such as the Tamagawa Josui Scenic Road and Nobidome Canal Historical and Environmental Preservation Area, and will provide spaces for relaxation and interpersonal exchanges that can be visited by the public. In these ways, Kawasaki hopes to achieve familiarity and acceptance among locals for the new facilities and replace the negative image fostered by conventional waste treatment facilities, while creating an open waste treatment center that contributes to the area as a hub for regional exchanges, disaster-prevention efforts and environmental education.

Demolition of existing facilities and new-facility design and construction will be carried out by a joint venture established with Asunaro Aoki Construction Co., Ltd., with Kawasaki serving as the representative organization. Facility operations will be handled by the special-purpose corporation Green Park Kodaira-Murayama-Yamato Co., Ltd., which is owned by Kawasaki, Kawasaki Environmental Plant Engineering Co., Ltd. and Metawater Co., Ltd.

Kawasaki boasts a wide range of waste treatment technologies in addition to the stoker incinerator and has been involved in the construction and operation of numerous municipal solid waste treatment facilities throughout Japan for more than half a century. The company will continue to develop innovations and deliver products in response to increasingly diverse environmental problems and societal needs.

*    Smart-ACC:
Smart Automatic Combustion Control. Proprietary, sophisticated combustion control technology by Kawasaki, designed to achieve more efficient and reliable power generation than conventional waste treatment facilities. Enables adjustment of generation output at a scale roughly double that of conventional systems (over the same time period), facilitating response more closely tailored to power supply demand.
