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 2018, the amount of waste generated decreased compared with fiscal 2017 as a result of the changes in the number of data aggregation companies. However, landfill disposal amounts increased. The primary reason for this increase was the sludge generated through maintenance at some sites. Atmospheric emissions of VOCs amounted to 759 tons in fiscal 2018, a decrease from fiscal 2017.
MHI Group will continue its efforts to reduce waste generation and VOC emissions.
