Management of Water Resources

In response to the increasingly critical water shortages and water pollution worldwide, the Teijin Group is endeavoring to reduce water consumption at business sites bearing in mind water-related risks, while promoting the efficient use of water resources.

Management of Water Resources

The Group’s targets (KPIs) for FY2030

By FY2030 improve the freshwater intake volume per sales unit by 30% compared with FY2018.

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 FY2022, the freshwater intake volume amounted to nearly the same level as it was in the previous fiscal year, at 66.5 million tons. This result constituted a 9% improvement in freshwater intake per sales unit compared with FY2021.

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.

Environmental Load due to Wastewater

In FY2022, wastewater volume was on a par with that of the previous fiscal year, at 60.2 million tons.

In addition, due to activities such as reduction of water usage for washing at dyeing factories, chemical oxygen demand (COD) decreased by 20% year on year to 209 tons, and biochemical oxygen demand (BOD) remained the same as the previous fiscal year at 80 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.

Water Risk Measures

The Teijin Group uses the Aqueduct water risk assessment tool of the World Resources Institute to analyze risks at manufacturing sites (26 sites). Based on a risk analysis conducted at each site, it has been determined that eight sites are located in areas with high water stress levels. At such sites, we are adopting measures to reduce risks such as creating projects to reduce usage in the product cleaning process.
