THE NEW VALUE FRONTIER

Water Risk Response

Water is a precious natural resource. Since water risk has been increasing in some parts of the world as a result of the ongoing impact of climate change, the Kyocera Group conducts water risk assessment. The Group set medium-term water consumption reduction targets (FY2025-2027) in addition to its annual water consumption reduction targets from FY2025 to ensure more effective and systematical use of water resources, and implemented water resource preservation measures.
The Kyocera Group assesses the natural environment and pressure on natural resources at each production site to identify locations that urgently require the implementation of water consumption reduction targets, and carefully manages the intake and discharge of precious water resources. For the assessment of the natural environment, the Group assesses the water stress level at each production site using Aqueduct Water Risk Atlas data provided by the World Resources Institute (WRI). The Group also assesses the pressure on natural resources using data such as water intake, unit price of water, and local-level water stress. Based on such information, the Group quantitatively assesses the water risk level at each production site. According to the water risk assessment in FY2024, there were two sites with high water risk, and the total water consumption was 4,484,000 ㎥, accounting for 29% of water consumption in FY2024.

Targets for FY2024 Implement measures to reduce water consumption by 116,000 m3.
(This target is applied to production sites with high water risk based on a water risk assessment.)
Achievements in FY2024 Implement measures to reduce water consumption by 100,064 m3.
Targets for FY2025 Implement measures to reduce water consumption by 54,000 m3.
(This target is applied to production sites with high water risk based on a water risk assessment.)
Targets for FY2025-2027
(Mid-term Targets)
Implement measures to reduce water consumption by 830,000 m3 in three years.
(This target is applied to production sites with high water risk based on a water risk assessment.)

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.

Reduced Water Consumption

180 thousand m3/year

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
