Waste / Pollution

As part of the Fifth MHI Group Environmental Targets (FY2021-FY2023), we set targets to reduce waste generation, including hazardous waste, promote thorough separation and reuse of waste, and reduce waste generation through minimizing process loss.
In fiscal 2020, the amount of waste generated is 146 thousand tons, decreased compared with fiscal 2019.
Regarding volatile organic compounds (VOCs), which are important air pollutants, we set internal targets to reduce levels of xylene, toluene, and ethylbenzene - chemicals that are emitted in large volumes - in the atmosphere, while continuously monitoring air emissions.
Atmospheric emissions of VOCs amounted to 741 tons in fiscal 2020, a decrease from fiscal 2019.
MHI Group will continue its efforts to reduce waste generation and VOC emissions.
