Each Mitsubishi Electric production base manufactures different products, and therefore generates different kinds of waste. Our general rule is to create and implement a different plan for each base. However, we also endeavor to share management expertise and information on contractors, and cooperate with neighboring bases.

Additionally, we have introduced a waste control system at all 26 Mitsubishi Electric production bases to implement stricter compliance.

Total waste output amounted to 87,000 tons in fiscal 2019, slightly down compared to the previous fiscal year, and the final disposal ratio was maintained at 0.001%.

Affiliated companies in Japan have also implemented measures that proved successful at Mitsubishi Electric production sites and continued to carry out thorough separation. Despite an increase in total waste output to 50,000 tons in fiscal 2019, the final disposal ratio was maintained at 0.01%.

It is difficult to set the same target levels as Japan for overseas affiliates, as regulations and waste treatment practices vary by country and region. Nevertheless, there are some activities that can also be implemented overseas, such as thorough separation, recycling, improvement in the efficiency of collection and transportation, and expansion in recycling of used plastics.

In fiscal 2019, we outsourced biomass treatment and utilized methane gas extracted after processes for fuels. Combining this initiative together with others, waste output totaled 77,000 tons, falling from the previous term. Although a final disposal ratio of 0.52% was an improvement over the previous fiscal year, we failed to achieve the target set.

Specification, Disposal and Transportation of Hazardous Wastes

The Mitsubishi Electric Group specifies hazardous wastes as follows, monitors their output and appropriately disposes of them in compliance with the laws and regulations of the regions in which our facilities are located. We also carry out material recycling and thermal recycling where we can in order to reduce final disposal (landfill) volume.

Wastes containing polychlorinated biphenyl (PCB) are managed separately based on the "Law concerning Special Measures for Promotion of Proper Treatment of PCB Wastes, PCB Special Measures Law.* Please refer to our Environmental Risk Management webpage for details.

In fiscal 2019, total hazardous waste emissions of Mitsubishi Electric amounted to 1,184 tons, of which, 901 tons was recycled. That of affiliates in Japan totaled 629 tons, of which, 618 tons was recycled, and that of overseas affiliates totaled 5,409 tons, of which 3,361 tons was recycled.
