Management of Water Resources

While promoting the efficient use of water resources, the Teijin Group is endeavoring to reduce water consumption at business sites bearing in mind water-related risks.

Management of Water Resources

In response to water shortages and water pollution, which are becoming increasingly serious worldwide, the Teijin Group in FY2019 stipulated a target relating to water resources up to FY2030 and began moves toward its achievement.

The Group’s targets (KPIs) for FY2030

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

Although the freshwater intake volume in FY2019 was 69.9 million tons, about the same level as in FY2018, the volume per sales unit rose 5% over FY2018. The wastewater volume was 61.7 million tons, down 6% from FY2018.

Toward the achievement of our target, we are expanding the number of products that use less water during the production process and making efficient use of water in our businesses activities.

Environmental Load due to Wastewater

In FY2019 the load due to wastewater (calculated from chemical oxygen demand [COD] and biochemical oxygen demand [BOD]) was 464 tons (up 19% over FY2018).

Water Risk Measures

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 promoting measures toward the reduction of water usage.

Trends in freshwater intake and water discharged

  • *The amount of freshwater intake is the total of industrial water, groundwater, and tap water.
  • *The amount of water discharged includes seawater used for cooling (until FY2016).

Trends in COD and BOD loads

  • *The tally covers wastewater discharged in rivers, sea areas, and lakes.
  • *At sites measuring both COD and BOD, the COD value is used if data exists.
