MHIEC Receives Order from Amachiku Environmental Office Association for Plant Modification Work to Extend Operational Life of Municipal Solid Waste Incineration Facility
-- Hachiho Clean Center in Aichi has 330 Tons/day Processing Capacity --


Tokyo, July 22, 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 Amachiku Environmental Office Association, an organization encompassing seven municipal entities in southwestern Aichi Prefecture, for modification work to improve core equipment at the Hachiho Clean Center, a municipal solid waste (MSW) incineration plant in Yatomi City. The modification work on order calls for revamping of three stoker furnace* type incinerators with a collective processing capacity of 330 tons per day (tpd), with the dual aims of maintaining the plant's operational functions and extending its operational life. The modification work is slated for completion in March 2018.

Municipal solid waste incineration plant in Yatomi
The Amachiku Environmental Office Association handles waste and sewage treatment for four local cities (Tsushima, Aisai, Yatomi, Ama), two townships (Oharu, Kanie) and one village (Tobishima). The Hachiho Clean Center was originally completed in May 2002, with design and construction performed by MHI. The current incineration facilities consist of three stoker furnaces each offering 110tpd processing capacity and related equipment. Power generation capacity at the plant is 5 megawatts (MW).

In the newly ordered work, age-deteriorated core incineration equipment will be fully replaced or partially upgraded. Applicable equipment includes waste hoppers and feeders; combustion gas cooler boilers; slag crane hydraulic buckets and curing conveyor components of the ash removal equipment; and, among electrical instrumentation, flue-gas analyzers.

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.

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.
