We are expanding the number of products that use less water during the production process and are using water efficiently in our business activities.

In these ways, we aim to achieve our targets for reducing the amount of freshwater intake with a focus on curtailing water use at manufacturing sites and other locations that use high volumes of water.

In fiscal 2021, the freshwater intake volume increased 6% compared with the previous fiscal year, to 66.6 million tons, as production activities recovered from the impact of the COVID-19 pandemic.

However, this result still constituted a 4% improvement in per sales unit compared with the previous fiscal year due to efforts to curtail water use at the Matsuyama Factory.

Trends in freshwater intake volume and volume per sales unit

• *The per sales unit has been assured since FY2021, and calculated by using consolidated net sales as the denominator.

In FY2021, wastewater volume increased by 6% year-on-year to 61.9 million tons due to recovery in production as a result of decrease in the impact of COVID-19.

In addition, due to activities such as reduction of water usage for washing at dyeing factories, chemical oxygen demand (COD) decreased by 14% year-on-year to 260 tons, bio-chemical oxygen demand (BOD) increased by 24% year-on-year to 79 tons.

Trends in freshwater intake and water discharged

• *The amount of freshwater intake is the total of industrial water, groundwater, and tap water.

Trends in COD and BOD

• *The tally covers wastewater discharged in rivers, sea areas, and lakes.
• *Until FY2021, COD values were used for sites measuring both COD and BOD values, but from FY2021, COD values have been tabulated for discharge into sea areas and lakes, and BOD values are aggregated for discharge into rivers.

The Teijin Group uses the Aqueduct water risk assessment tool of the World Resources Institute to analyze risks at manufacturing sites. At the present point in time, there are no sites harboring serious risks, but at sites in regions where there are concerns that water usage might be limited, we are adopting measures such as creating projects to reduce usage in the product cleaning process.
