MHI to upgrade Fuskushima waste-to-energy plant

Mitsubishi Heavy Industries Environmental & Chemical Engineering (MHIEC), has received an order from the Fukushima Municipal Government to upgrade the city's Abukuma Clean Center Incineration Plant.

The plant was originally designed and built by Mitsubishi Heavy Industries in 1988.

The upgrade will see the installation of two stoker-type incinerators collectively capable of processing 120 tons per day (tpd).

According to Mitsubishi Heavy Industries (MHI), stoker incinerators are the most widely adopted type of furnace used in waste-to-energy plants. Waste is combusted as it moves along on a fire grate made of heat-resistant castings.

The upgrade, scheduled to begin operating in April 2028, will reduce emissions, decreasing the environmental footprint of the facility and will increase the efficiency of power generation.

The upgrade will see the heat energy generated during waste processing used to supply power to a nearby recycling plant and the health facility, Healthyland Fukushima, which will also receive high-temperature water.

The ¥23.86 billion ($159 million) contract will also include the provision of operation and maintenance services for 20 years.

For the contract, MHI submitted the winning bid which included the adoption of a new local electric power source with a 100% renewable energy ratio by a local company, the use of waste-derived construction materials in the building to save resources, the use of a wooden administration building to enhance the view seen by visitors and from prefectural roads, and consideration of the landscape.

In constructing and operating the waste-to-energy facility, MHIEC will work closely with a group of three local companies in Fukushima City.
