We are working to reduce emissions of hazardous chemical substances through ongoing efforts to prevent leaks of such substances and the transition to processes that create less emissions.

In FY2022, despite ongoing efforts to reduce emissions and prevent leaks of hazardous chemical substances in the carbon fibers and resin and plastic processing businesses, our hazardous chemical substance emissions increased 5% compared with the previous fiscal year, to 780 tons, due to such factors as an increase in the number of facilities in the composites business. This result still amounted to an improvement of 4% in per sales unit compared with the previous fiscal year.

Top 10 chemical substance emissions

NOx emissions resulting from fuel use were down 14% from the previous fiscal year at 0.90 thousand tons, while SOx emissions generated in the same manner decreased 9% from the previous fiscal year at 2.13 thousand tons. Meanwhile, emissions of volatile organic compounds (VOCs) increased 16% from the previous fiscal year to 1.56 thousand tons.

In addition to conforming to each country’s and territory’s legislation relating to the prevention of soil pollution, the Teijin Group formulated guidelines for preventing soil and groundwater pollution. Under these guidelines, we are striving to prevent soil and groundwater pollution resulting from our business operations.
