THE NEW VALUE FRONTIER

Water Risk Response

Water is a precious natural resource. The importance of water resources, and water risk, is increasing in some parts of the world because of the ongoing impacts of climate change.
Water is a precious resource, and the Kyocera Group carefully manages its intake and release, as well as quantitatively assessing water risk at each production site using data from the Aqueduct Water Risk Atlas* such as water stress level, amount of water use, unit price of water, and local-level water stress assessment results.
As a result of the FY2022 water stress assessment, there were 4 sites with high water risk, and the total water consumption was 4,272,000 m3, accounting for 24% of water consumption in FY2022.

Targets for FY2022 Implement measures to reduce water consumption by 61,000 m3.
(This target is applied to production sites with high water risk based on a water risk assessment.)
Achievements in FY2022 Implement measures to reduce water consumption by 80,285 m3.
Targets for FY2023 Implement measures to reduce water consumption by 25,000 m3.
(This target is applied to production sites with high water risk based on a water risk assessment.)

As a result of reviewing the data of FY2020 onward, the figures have been revised.

Water Conservation Efforts

Reusing Air-Conditioning Cold Water

The Toyama Nyuzen Plant uses groundwater as a cold-water source for air conditioning. The cold water had previously been used for cooling compressors or as supplementary water for the cooling towers. However, a new process has reduced water consumption by reusing the air-conditioning water as rinse water and coolant in manufacturing processes.

Reusing Process Wastewater

KYOCERA Document Technology (Dongguan) Co., Ltd. uses a water recycling system to neutralize wastewater from the cleaning process, store it in a tank, and reuse it as cooling water for air conditioners, thereby reducing wastewater discharge by an average of 4,600 m³ per month.

Reduced Water Consumption

55,200 m3/year
