Waste / Pollution

As part of the Fourth MHI Group Environmental Targets (FY2018–FY2020), 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. Regarding volatile organic compounds (VOCs), we set internal targets to reduce levels of xylene, toluene, and ethylbenzene—chemicals that are emitted in large volumes—in the atmosphere.
In fiscal 2019, the amount of waste generated decreased compared with fiscal2018. Atmospheric emissions of VOCs amounted to 815 tons in fiscal 2019, a decrease from fiscal 2018 .
MHI Group will continue its efforts to reduce waste generation and VOC emissions.
