Water Resource Usage<\/h2>\n\n\n\n
The company's Linkou plant, located in Hwa Ya Industrial Park, receives its main water supply from Shimen Reservoir, with wastewater discharged to the South Wastewater Treatment Plant managed by Hwa Ya Consulting Co., Ltd. The Xinzhuang plant also sources its water from Shimen Reservoir, with wastewater discharged to Bali Wastewater Treatment Plant. According to the Water Resource Risk Assessment Tool, the company's water resource risk is classified as medium to low risk.
The company has long focused on water conservation and environmental protection. In its water-saving plan, the company emphasizes daily water conservation practices and actively improves the water consumption of its processes to maximize the use of available water resources. The Company's water consumption in 2025 was 4,861 metric tons, representing a 20.71% decrease compared to 6,131 metric tons in 2024, indicating continuous improvement in water use efficiency. In the future, the Company will continue to promote water conservation measures and set a target of reducing water consumption by an additional 1% in 2026 compared to 2025, further enhancing the effectiveness of water resource management.<\/div>\n\n\n\n
