As part of the $54.9m (JPY5.84bn) contract, MHIEC will enhance the life of the facility by overhauling and improving stoker type incinerators and associated equipment.
The facility was designed and constructed by Mitsubishi Heavy Industries (MHI) in 2004 and has a capacity to generate 15.2MW of electricity to power the equipment in the factory.
Scheduled to be completed in March 2023, the refurbishment project will see the renewal of superannuated core components at the facility.

The refurbishment of the facility is expected to reduce carbon emissions by 9.6% annually.
By refurbishing the facility, the government aims to extend the life of the waste to energy facility and minimise the environmental impact. The Japanese government established a related subsidy system to accelerate this trend in 2010.
