MHIEC Receives Order from Bisan Sanitation Association in Aichi Prefecture for Refurbishment of Key Components of MSW Incineration Plant with 200 Tons/day Processing Capacity -- Work Aimed at Extending Facility's Service Life --

Tokyo, September 29, 2015 -- Mitsubishi Heavy Industries Environmental & Chemical Engineering Co., Ltd. (MHIEC), a group company of Mitsubishi Heavy Industries, Ltd. (MHI), has received an order from the Bisan Sanitation Association, an organization consists of three municipalities in central Aichi Prefecture, to refurbish the core components of a municipal solid waste (MSW) incineration plant. The order calls for refurbishment of stoker type incineration plant (Notes 1) with a total capacity of 200 tons per day (tpd), to maintain their proper functioning and extend their service life. The work is slated for completion in March 2020.

The Bisan Sanitation Association handles waste treatment for the cities of Nisshin and Miyoshi and the town of Togo, where it is based. The MSW incineration plant, which is located at the Togo Environmental Beautification Center, was designed and constructed by MHI and completed in November 1997. The plant incorporates two stoker incinerators each offering 100tpd capacity and auxiliary equipment.

The order placed to MHIEC calls for the refurbishment of the plant's key components. Work will consist of replacement or revamping (partial replacement) of superannuated equipment used primarily for incineration, combustion gas cooling, flue gas treatment, ventilation, ash handling, and water supply and discharge. The refurbishment project will also target enhanced energy conservation, largely through the adoption of high-efficiency motors in key equipment, and a greater than 3 percents reduction in CO2 emissions, thereby contributing to curbing of global warming.

Recently the number of projects to modify and improve existing MSW incineration plants, both to extend their operational lives and to reduce their impact on global warming, is in an increasing trend as local governments face tight budgets that make it difficult to construct new facilities. Moves in this direction are also gathering further momentum with the central government's introduction in 2010 of a state subsidy system created to promote operational life extension and enhance energy savings of waste treatment facilities (Notes 2).

MHIEC took over MHI's waste treatment plant business in 2008, acquiring MHI's technological development capabilities in environmental systems and its abundant expertise in the construction and operation of waste management facilities both in Japan and overseas. Based on its strong track record, MHIEC today is in a prime position to provide comprehensive solutions incorporating all aspects from plant construction to operation.

Leveraging this latest order and its solid track record, going forward MHIEC will proactively propose further energy-saving enhancements and system improvements for stable operation at existing waste treatment facilities as well as ways to reduce lifecycle costs, including operation and maintenance costs, in a quest to expand its business in this field further.

(Notes 1) A stoker furnace is a common feature of MSW incineration plants. In a stoker furnace, MSW is combusted as it moves along on a fire grate made of heat-resistant castings.

(Notes 2) This program, which falls under the jurisdiction of Japan's Ministry of the Environment, targets effective use of existing waste treatment facilities as a contribution to the prevention of global warming. Local (city, town or village) governments that seek to extend the operational life of their MSW facilities are eligible to receive subsidies covering one-third to half of the project cost, dependent on the CO2 reduction rate.
