Reduce Critical Material Usage

Effort Status

• With our environmental goal to "use resources effectively and reduce waste", to protect water resources we are working toward a goal of water usage output level reduction of 30% against FY2013 levels by 2030.
• We use both well water and municipal water supplies, and strive to reduce consumption across both sources. Because many surface treatment systems require large volumes of water for cleaning, and usage fluctuates with production volume, our reduction targets are set based on usage intensity.
• Surface treatment water is treated with counteragents, etc. before being drained into the sewerage system. By reducing the amount of water we use, it protects the environment and saves on expenses, too.
• In FY2025, total water usage decreased by 42.8% compared with FY2013.
  Compared with the previous year, there was a 9.7% increase, resulting from safety measures-such as running water to prevent pipe freezing-implemented during a record cold winter, particularly at the Nagano Plant.
