Kashima Joint Combustible Waste Clean Centre

Mitsubishi Heavy Industries Environmental & Chemical Engineering (MHIEC), a part of Mitsubishi Heavy Industries (MHI) Group, has completed construction of a waste-to-energy plant in Kamisu city in Ibaraki Prefecture, Japan. Full-scale operation of the plant, named the Kashima Joint Combustible Waste Clean Center, has been underway since the beginning of April 2024.

MHIEC received the order for the plant in 2020 from the Kashima Regional Administration Association, which comprises the cities of Kashima and Kamisu. The new plant consolidates and replaces two combustible waste management facilities previously operated in Kashima and Kamisu and enables integrated incineration of the two cities’ combustible waste.

Equipped with two stoker type incinerators, each having a waste treatment capacity of 115 tonnes per day, the facility also includes a power generation system for energy recovery. The stoker incinerator technology used is the most widely adopted furnace type in waste-to-energy plants, where waste is combusted as it moves along on a fire grate made of heat-resistant castings.

MHIEC succeeded to MHI’s environmental systems business in 2008, incorporating its accumulated technological development capabilities in environmental systems, giving MHIEC capacity to propose comprehensive solutions encompassing everything from plant construction to operation. The company aims to proactively offer proposals for new waste management facilities, together with:

•   solutions for efficiently recovering energy from waste;
•   enhancing the energy efficiency of existing plants;
•   improving incinerator performance through support for remote monitoring and autonomous operation applying AI and IoT;
•   and lowering lifecycle costs.

MHIEC aims to expand its orders for waste-to-energy plants both in Japan and overseas.
