MHIEC Receives Order to Refurbish Core Components of 390 tons per day MSW Incineration Plant in Iwaki City, Fukushima Prefecture -- Work Aimed at Extending Facility's Service Life --

Tokyo, January 14, 2016 -- Mitsubishi Heavy Industries Environmental & Chemical Engineering Co., Ltd. (MHIEC), a Group company of Mitsubishi Heavy Industries, Ltd. (MHI), has received an order from Iwaki City in Fukushima Prefecture to refurbish the core equipment of the Nambu Clean Center, a municipal solid waste (MSW) incineration plant. The order calls for refurbishment of three stoker (Notes 1) type incineration plant with a total capacity of 390 tons per day (tpd), to extend the Center's service life by at least 18 years and achieve enhanced energy efficiency. The order is valued at 5.15 billion yen (excluding taxes). The work, part of a four-year project, is slated for completion in March 2019.

The existing Nambu Clean Center was designed and constructed by MHI and completed in March 2000. The facility incorporates three stoker incinerators each having a processing capacity of 130 tpd. It can generate up to 3.5 megawatts (MW) of electricity.

The order newly placed with MHIEC calls for replacement or refurbishment of the superannuated facility's core equipment, used primarily for waste receiving, feeding and incineration, combustion gas cooling, flue gas treatment, ventilation, ash removal and water supply, plus electrical and instrumentation systems. The project also targets enhanced energy efficiency, largely through the adoption of MHIEC's patented "new combustion control system," which contributes to stable combustion, and the incorporation into all key system components of the Company's high-efficiency motors and inverters. With these measures the refurbished plant's CO₂ emissions will be reduced by 350 tons, or more than 5.7 percent, per year, thereby helping to curb global warming.

Recently the number of projects to improve existing MSW incineration plants, both to extend their service lives and to reduce their impact on global warming, is in an increasing trend. Moves in this direction are also gathering further momentum with the central government's introduction in 2010 of a state subsidy system (Notes 2).

MHIEC took over MHI's waste treatment plant business in 2008, acquiring MHI's technological development capabilities in environmental protection 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 encompassing all aspects from plant construction to operation.

Going forward, MHIEC will leverage its solid track record, including this latest order, and proactively propose further energy-saving enhancements and system improvements for stable operation at existing waste incineration facilities. In addition, the Company will work to reduce lifecycle costs, including operation and maintenance, in a quest to further expand business in this field.

(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, promotes effective use of existing waste treatment facilities as one measure to address the issue of global warming. Local (city, town or village) governments that seek to extend the operational life and lessen the environmental impact of their MSW facilities receive subsidies covering one-third of their project costs.
