Water Resources in Our Business Activities

As a chemical manufacturer, our group recognizes its dependence on water resources for the water withdrawal required in our production activities, as well as the impact on local areas caused by discharges into water bodies. Our group is committed to the effective use of limited and precious water resources, and to reducing water risks through preventing water pollution and rigorous wastewater management. We believe these efforts contribute to the conservation and sustainable use of regional water environments.

The identification, assessment, and management of risks and opportunities related to environmental issues pertaining to our Group (including conservation of water resources) are carried out in accordance with the risk management structure and risk management processes described on the following page.

Assessment of water-related risk

We conduct an annual assessment of water related risks in the watersheds of 18 domestic and 27 overseas locations where our domestic and overseas group sites are situated.
In fiscal year 2024, we carried out a comprehensive water related risk assessment that included confirming the water stress conditions at each site as well as evaluating other risk factors.

・Water Stress at Production Sites

Using the WRI Aqueduct* as an assessment tool, we reviewed the water stress conditions in the countries and regions where our production sites are located.
As a result, high water stress was confirmed at some sites in Europe and China.

・Assessement Water-Related Risk at Production Sites

In addition to assessing the water stress conditions at each site, we evaluated various risks such as flood risk, water quality risk, regulatory risk, and reputational risk.
Based on these information, we conduct assessments that incorporate our company’s unique surveys and the water usage status at each site to comprehensively understand water-rerated risks by country and region.
In terms of our overseas business sites, although there are few sites with high water withdrawal, regional water risks are emerging in Southeast Asia and China, requiring continued attention.
Moving forward, we will continue these assessments and promote initiatives for the conservation of water resources.

Conservation of water resources

At our European and Chinese business sites in recent years, we have been working on initiatives for reusing water as industrial water by purification and treatment using a system that combines biological treatment (purification by microorganisms) and separation technology (separation such as by microfiltration membrane) of chemical wastewater emitted from plants. As a result, the amount of utility water used has been reduced by at least 50% at these business sites.

Moving forward, we are promoting activities aiming for both manufacturing activities and reduction of water withdrawal for sustainable use of water resources.
