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, our objective is to reduce the final amount sent for landfill compared with the previous year. In 2018, however, the final amount of industrial waste we sent for landfill rose year-on-year, because production output increased in response to strong demand while the volume of business we did in valuables fell and we accelerated our equipment maintenance/repairs and disposal of idle assets.

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.
