MHIEC Receives Order for Plant Modification Work to Extend Operational Life of Municipal Solid Waste Incineration Facility
In Fukuchiyama City, Kyoto Prefecture
-- 150 Tons/day Capacity Fukuchiyama Environmental Park --

Tokyo, November 11, 2013 - Mitsubishi Heavy Industries Environmental & Chemical Engineering Co., Ltd. (MHIEC), a group company of Mitsubishi Heavy Industries, Ltd. (MHI), has received an order for modification work to improve core equipment at the Fukuchiyama Environmental Park, a municipal solid waste (MSW) incineration plant in Fukuchiyama City, Kyoto Prefecture. The modification work calls for revamping of a stoker furnace*1 type incineration plant with a processing capacity of 150 tons per day (tpd), now in its 13th year of operation, with the aims of extending the plant's operational life and boosting its energy-saving capability. The modification work, valued at 1.86 billion yen, is slated for completion in March 2017.

The incineration plant was originally engineered and constructed by MHI and completed in February 2000; it consists of two 75-tpd stoker furnaces and peripheral facilities. The modification work on order calls for renewal and conversion of the plant's major equipment, including the flue-gas treatment system, ventilation system and electrical instrumentation. Energy saving is to be improved primarily through the adoption of high-efficiency motors, and carbon dioxide (CO2) emissions will be reduced by more than 4.9% (approx. 227 tons) per year, thus contributing to curbing global warming. The adoption of MHIEC's patented Hybrid Bag Filter, incorporating Hybrid Bag Filter (HBF)*2, a catalyst bag filter, will eliminate the need for activated carbon, which has been used to reduce the level of dioxins in the flue gas, and thereby enable reductions in the plant's operating costs.

Recently the number of projects to modify and improve existing MSW incineration plants, both to extend their operational lives and make them more environmentally compatible, has been in an increasing trend as local governments face tight budgets that make it difficult to construct new facilities. Moves in this direction have also gathered 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*3.

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, built up from the company's long track record in this area. Leveraging these assets, MHIEC is in a prime position to provide comprehensive solutions encompassing all aspects from plant construction to operation.

The order for modification work at the Fukuchiyama Environmental Park represents the second of its kind received by MHIEC during the current business year, following an earlier order for a facility in Hiroshima City. Leveraging these consecutive orders 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 maintenance and management 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.
2. Hybrid Bag Filter is MHIEC's original products, the functions of which have been
    enhanced by coating a catalyst on bag filter fibers to add gaseous dioxins (DXNs) and
    nitrogen oxides (NOx) reduction functions, while maintaining the conventional functions
    to remove other harmful substances.
3. This program, which falls under the jurisdiction of Japan's Ministry of the Environment,
    targets effective use and improvement of existing waste treatment facilities as a
    contribution to the prevention of global warming. Local governments (city, town or village)
    that seek to extend the operational life of their general waste processing facilities are
    eligible to receive subsidies covering one-third to half of the project cost, dependent
    on the CO2 reduction rate.
