To reduce our environmental burden at Tokai Carbon, we not only take measures required by various laws, but also strive to reduce environmental pollutants based on our voluntary standards that are stricter than current laws. As for low-density PCB waste, we have set a target of disposing all low-density PCB waste owned by the end of March 2025, two years ahead of the legally specified deadline.
We have disposed 52% of volume by 2021 and the remainder (48%) will be continuously disposed to achieve the target.
As for industrial waste, we will focus on further reduction of consignment disposal volume and overall disposal volume, by thoroughly separating waste and recycling.
At Tokai Carbon, we produce various types of carbon products from raw materials such as petroleum pitch, feedstock, natural gas, and so on. To use resources more efficiently, we are making ongoing improvements to our production methods enabling us to produce more products with fewer raw materials.
