Water Resources Risk Management

Ardentec's primary water usage is for the air conditioning cooling water required for 24-hour plant operations, followed by domestic water for employees and water used for firefighting purposes. In 2024, Ardentec's total water withdrawal was 391,513 metric tons, with total wastewater discharge amounting to 187,318 metric tons. All water sources are supplied by municipal tap water, and the water withdrawal points are located at government-designated supply points at each operational site. There are no anticipated negative environmental or species impacts from the water extraction. Ardentec uses the "Aqueduct Water Risk Atlas" tool developed by the World Resources Institute (WRI) to assess the water risk levels at the headquarters and subsidiary locations. By examining water sources and total water withdrawal data, we gain insights into the Company''s overall water usage, potential impacts, and associated risks, enabling us to enhance water conservation efforts. Ardentec's operational sites in Taiwan, Singapore, South Korea, and Nanjing are located in low or low-moderate water stress areas.

 

Water Conservation Management

Although Ardentec is not a water-intensive enterprise due to its relatively low water consumption, the Company remains committed to the goals of reduction, recycling, and reuse of water resources. Ardentec continuously implements water-saving initiatives, such as upgrading water-saving equipment, recovering air conditioning condensate, and reusing reverse osmosis (RO) reject water from production processes as supplementary water for cooling systems. These measures maximize water resource circulation, reduce overall water consumption, and enhance water conservation performance. In 2024, the Talent Site at the headquarters introduced new recycling and filtration systems for cooling water discharge, air conditioning, and air compressor condensate, enabling water to be recirculated and reused. The combined water recycling volume at the headquarters and the Nanjing subsidiary reached 41,070 metric tons, accounting for 10.5% of total water withdrawal. The cost savings generated from water reduction initiatives have been reinvested into environmental education related to water resources, contributing to a positive cycle of the Company's green management system.
