Initiatives to Prevent Air and Water Pollution
Toray Group works continuously on environmental conservation measures at its production sites. Ongoing initiatives that it will continue include reducing sulfur oxide (SOx) emissions by installing desulfurization equipment and switching to cleaner fuels, and reducing biochemical oxygen demand (BOD) and chemical oxygen demand (COD) through stable operation and expansion of wastewater treatment facilities.
Air Emission Management
In fiscal 2020, Toray Group recorded 1,583 tons of SOx emissions (down 15% year on year), 2,190 tons of nitrogen oxide (NOx) emissions (flat year on year), and 196 tons of dust emissions (down 45% year on year). The year-on-year reduction in SOx emissions was due to the use of low sulfur concentration coal by group companies outside of Japan, and that of dust was due to the stable operation of dust removal equipment.
Wastewater Quality Management
Toray Group monitors and complies with regulations concerning BODs, CODs, and nitrogen in countries and regions where it operates plants and implements water quality management for plant wastewater. Plants with high effluent loads are reducing effluents by installing wastewater treatment facilities (activated sludge method) that utilize the activated sludge method and other techniques. The Group is committed to remaining in compliance with regulations through everyday facilities operation management and regular self-testing of water quality.
In fiscal 2020, Toray Group recorded 733 tons of BOD emissions (down 14% year on year) and 1,945 tons of COD emissions (down 16% year on year). This year, the water quality of plant effluent improved with a decrease in the effluent load on activated sludge equipment due to a decrease in production volume.
The Group brings together wastewater managers every year to share and discuss strategies for enhancing wastewater management at production sites. The fiscal 2020 meeting was attended by 38 persons from Toray Industries’ plants and 15 persons from group companies in Japan.
