Environmental Sustainability

In recent years, climate anomalies have intensified, increasing the risk of water shortages. Efficient water resource management has become critical for maintaining operational stability and fulfilling corporate sustainability responsibilities. To address this, OSE introduced the ISO 46001:2019 Water Resource Efficiency Management System in 2022 and has successfully passed third-party verification. This system enables systematic water use identification, risk analysis, and management planning to ensure efficient water use and resource control.

Following recognition by the Water Resources Agency in 2022 with the “Water Conservation Guidance Improvement Award Unit (Industrial Group Special Excellence),” OSE continues to strengthen system promotion and on-site application. Key focus areas for 2024 include：
• Enhancing the recycling rate of process wastewater and strengthening reuse capabilities at Central 3rd Factory (HQ) and Jing 3rd Factory (AT)；
• Activating continuous wall seepage and water flow monitoring management;
• Expanding recycled water use within plant areas to reduce reliance on external water supply;
• Continuing independent water-saving initiatives within factories to improve overall water resource management resilience.

Through the dual-track advancement of management systems and technological innovation, OSE effectively implements water resource efficiency in daily operations, demonstrating a concrete commitment to environmental sustainability.
