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.
For industrial waste, we will focus on improving recycling rates, by thoroughly separating waste and recycling. In 2024, we have expanded the scope to include Tokai Carbon and its major domestic and overseas group companies, and set the recycle rate target to 50% or higher*, and have achieved the target with the recycle rate target to 58.5%. For 2025, the scope of the target will continue to be consolidated(Tokai Carbon and its major domestic and overseas group companies)and we will work towards our target of the recycle rate target to 51% or higher.
*Recycle rate (%) = Recycled weight (Recycled weight of waste) / (Weight of generated waste) x 100

To reduce the environmental burden on the atmosphere, we are working to reduce emissions of nitrogen oxides (NOx), sulfur oxides (SOx), and volatile organic compounds (VOCs). In 2024, we have expanded the scope to include our consolidated companies (Tokai Carbon and major domestic and overseas group companies) and have set the targets of "NOx emissions: 3,400 tons or less/year (base year: 2021)," "SOx emissions: 18,600 tons or less/year (base year: 2021)," and "VOC emissions: 280 tons or less/year."
As a result, we achieved our targets: NOx emissions: 2,843t/year, SOx emissions: 11,132t/year, VOC emissions: 167t/year. For 2025, the scope of the target will continue to be consolidated(Tokai Carbon and its major domestic and overseas group companies)and we will work towards our targets : NOx emissions: 3,330 t/y or less (2% reduction against 2021), SOx emissions: 17,670 t/y or less (5% reduction against 2021), VOC (Volatile Organic Compounds): 265 t/y or less (5% reduction against 2022).

Efficient use of resources

At Tokai Carbon, we produce various types of carbon products from raw materials such as pitch, coke, 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.

Responding to regulations regarding chemical substances

Tokai Carbon carries out strict control of chemical substances that are hazardous and toxic to human health or to the environment, and is actively engaged in reducing their use. Furthermore, Tokai Carbon has set the following substances as “Prohibited Substances” and prohibits the manufacture and sale of products that contain these Prohibited Substances.
