Pollution and resource


Activities to reduce environmental burden

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 goal of disposing all low-density PCB waste by the end of March 2025, two years ahead of the legally specified deadline.
As for industrial waste, we will focus on further reducing contracted disposal volume and cutting down final disposal volume by thoroughly separating waste according to type and recycling waste materials.

Efficient use of resources

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.
