CSR GUIDELINE 3 Emphasize Safety, Accident Prevention, and Environmental Preservation

Initiatives to Prevent Water Pollution

Toray Group purifies all wastewater from plant production activities with activated sludge treatment and other systems before release. Although we were not able to meet COD targets, we came extremely close to meeting BOD targets because of improvements in manufacturing processes and wastewater treatment facilities.

Toray Group Performance

Efforts to meet the Second Three-Year Environmental Plan target of reducing BOD emissions by 20% were only able to achieve a 19% reduction due to an emissions increase of 150 tons over FY 2006.

Although we reduced COD emissions by 11% compared to the base year, a year-on-year increase of 1.7% prevented us from reaching our voluntary reduction target. Going forward, we will be redoubling process improvements and wastewater stabilization.

BOD emissions at Japanese subsidiaries and affiliates increased 2% year-on-year due to increasing production, while COD emissions fell 10%.

BOD emissions at overseas subsidiaries and affiliates rose 3% year-on-year in Southeast Asia and China, while COD emissions fell 5%.

Water Emissions (Toray)

Note: BOD figures include all 12 plants and 1 research center. COD figures include the 6 plants subject to Total Pollutant Load Control.

Water Emissions (Japanese Subsidiaries and Affiliates)

Note: BOD figures include 24 plants at 19 companies. COD figures include the 7 plants subject to Total Pollutant Load Control.

Water Emissions (Overseas Subsidiaries and Affiliates)

Note: BOD and COD figures reflect totals for 33 plants at 24 companies

Initiatives at Toray


The Ehime Plant's new MBR treatment facility

Water quality improvement efforts at the Ehime Plant included the construction of a new MBR treatment facility, which began operation in August 2006. Compared to conventional treatment facilities, the plant's high throughput allows it to output treated water at a higher level of purity while maintaining higher activated sludge concentrations.

Initiatives at Japanese Subsidiaries and Affiliates


Liquid waste spray combustion equipment at TFC (Chiba)

Zero emissions initiatives at the Chiba Plant of Toray Fine Chemicals Co., Ltd. (TFC) include completely breaking down highly concentrated organic liquid waste in spray combustion equipment and treating liquid waste generated during the polysulfide polymer manufacturing process with activated sludge and activated carbon adsorption equipment to reduce COD concentrations to 5 mg/l or lower levels.

Initiatives at Overseas Subsidiaries and Affiliates


New wastewater treatment facility at TPSZ in China

Toray Plastics (Shenzhen) Ltd. (TPSZ) constructed a new anaerobic coagulation treatment facility capable of processing 300 cubic meters of wastewater from its resin compound manufacturing process daily.
