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. In fiscal 2019, the amount of waste generated is 170 thousand tons, decreased compared with fiscal 2018 as a result of the changes in the number of data aggregation companies.
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. As a major example, MHI developed VOC-free, solventless paints in partnership with a Japanese paint maker, and significantly reduced VOC emissions in the process of coating metallic aircraft parts.. 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.
