Toray Group works continuously on environmental conservation measures at its production sites. It is working to prevent air pollution caused by volatile organic compounds (VOCs), sulfur oxides (SOx), nitrogen oxides (NOx), and dust emissions, as well as to prevent water pollution by reducing biochemical oxygen demand (BOD) and chemical oxygen demand (COD).
Given that Toray Group processes involve many organic chemicals, reduction of atmospheric VOC emissions has been identified as a top priority. Under the Group’s CSR Roadmap 2025, covering fiscal years 2023 to 2025, KPIs have been established to drive this initiative.
Going forward, the Group will continue efforts to reduce VOCs and other air pollutants by installing recovery systems and switching fuels. It will also keep decreasing BOD and COD through stable operation and expansion of wastewater treatment facilities.

In fiscal 2024, Toray Group’s atmospheric VOC emissions were 996 tons, down 8.8% (97 tons) compared to the previous fiscal year.
The emissions were 74.9% below the base year of fiscal 2000, achieving the CSR Roadmap 2025 target of a 72% reduction compared to the base year.
Going forward, as it works on business expansion, the Group will keep striving to achieve the KPI set under the CSR Roadmap 2025, namely, an annual reduction target of 72% or more compared to fiscal 2000. To achieve this goal, the Group will designate companies with high VOC atmospheric emissions as companies subject to supervision and work with these companies to further reduce emissions.

The Group will also keep voluntarily reducing atmospheric emissions of substances subject to the PRTR Act, which include chemicals of concern due to potential health impacts, while closely monitoring regulatory trends in each country or region where its production sites are located.
In fiscal 2024, total atmospheric emissions of PRTR-regulated substances across the Toray Group amounted to 699 tons. This represented a 73.4% reduction compared to the base year of fiscal 2000.

Air Pollutant Management

In fiscal 2024, Toray Group recorded 386 tons of SOx emissions (down 20% year on year), 2,315 tons of nitrogen oxide (NOx) emissions (down 15% year on year), and 239 tons of dust emissions (down 62% year on year). These reductions were mainly due to the decline in coal-fueled boiler operations at group companies outside of Japan.

Water Pollutant 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 2024, Toray Group recorded 560 tons of BOD emissions (down 11% year on year) and 1,944 tons of COD emissions (down 5% year on year). These improvements are the result of enhancement of wastewater treatment process efficiency and other efforts.
Moving forward, Toray Industries will further strengthen the technical support provided to group companies to achieve greater reduction of effluent loads.

Furthermore, to enhance wastewater management levels at each production site, the following initiatives are being implemented:

1. Wastewater Management Information Exchange Meetings
   Annual wastewater management information exchange meetings are held for wastewater management personnel. The fiscal 2024 meeting was attended by 45 persons from Toray Industries’ plants and 36 persons from group companies in Japan.
2. Technical Guidance and On-Site Training
   Since fiscal 2022, Toray Group has been conducting facility surveys and holding guidance meetings on operation and management with the aim of achieving consistent performance at wastewater treatment facilities. By fiscal 2023, these activities were completed at sites in Japan, and from fiscal 2024 the scope has been expanded to overseas sites. In Thailand and Malaysia, surveys and technical guidance were carried out at group companies.
