Water Resources
Basic approach and policy
Our Group takes the effective use of water resources as an important business issue and has set a target for the amount of water used and is working to ensure the effective use of water resources.
Governance and risk management
For more details, “Environmental Management”.
Strategies
Reduction of water usage
Our Group uses water in our manufacturing processes, as well as for cooling and
cleaning.
At five of the ten sites that require water management plans, including both domestic and
overseas sites, we are promoting the plan and are striving to ensure effective use of water
resources. We are striving to reduce water usage by reducing the use of cooling water
through the implementation of better manufacturing methods and by reducing the use of water
through the optimization of cleaning methods and additions of cooling water recycling
equipment. The Production Division in Japan, which uses a particularly high amount of water,
reports monthly to the Environment and Safety Committee on the reasons for increases or
decreases, as well as the reduction measures implemented. In FY2024, the amount of water use
increased by 5.6% year on year due to an increase in production volume.
Wastewater treatment
Since we installed a wastewater treatment system at the Fukaya Facility in 1969, we have
been installing and upgrading wastewater treatment facilities in our production
facilities using various water purification technologies, such as the activated sludge
method, dissolved air floatation method, anaerobic method, coagulation and sedimentation
method, and the membrane filtration method.
Wastewater from production facilities is treated through a tertiary treatment process.
Wastewater from the R&D Center is treated until the secondary treatment process before
being discharged to the sewer system. We comply with wastewater standards in terms of
regulation values, etc., as prescribed in the Water Pollution Control Law, prefectural
ordinances, and agreements with communities.
Water stress analysis
In addition to addressing climate change, our Group is working to establish a system for
managing water risk strategies and initiatives through the company-wide Environment and
Safety Committee, in response to the growing global interest in and importance of water
resources.
We analyze water stress using the Aqueduct Water Risk Atlas from the World Resources
Institute (WRI) and the WWF’s Water Risk Filter. We recognize that water risk is not high in
our production areas in Japan; however, four sites in our U.S. and China production areas
have been identified as being under high water stress. For example, at our sites in China,
where water stress is high, we have set a target of keeping water consumption per unit of
production below the five-year average. To achieve this, we are focusing on measures such as
increasing continuous production and reducing the frequency of equipment washing.
We recognize that water is a vital global resource and that strengthening water management
is essential. We will continue to address this issue appropriately. We will continue working
to reduce water usage while monitoring the progress of our measures for achieving our
reduction targets.
Indicators and targets
In FY2024, we reduced water usage by 2.7%, exceeding our target of 2.1% reduction per unit of
production year-on-year.
