Water Resource Management

With the rising frequency of extreme weather events, water stewardship has become increasingly critical. Because Ventec operates in multiple countries and regions, water use at each site is closely linked to local natural conditions and regional water-stress levels— making a robust water-management strategy essential. Accordingly, we treat water management as a key component of operational risk control, focusing on improving water-use efficiency and reducing environmental impact.Ventec uses the WRI Aqueduct Water Risk Atlas to assess overall water risk at each operating site. Except for the Suzhou Plant, our sites are not located in high water-stress areas. To address local water stress, the Suzhou Plant continued to strengthen water-circulation and reuse mechanisms, increasing the reuse ratio from 31.27% in 2023 to 33.04% in 2024. In production, filtration and sedimentation equipment are used so that treated water can be returned to the process for recycling. Conductivity sensors continuously monitor quality: when conductivity reaches 1,600 μS/cm the system automatically initiates discharge; it stops when conductivity falls to 1,500 μS/cm, thereby maintaining stable water quality and avoiding unnecessary water use.To manage water responsibly, we compile wateruse statistics for all operating sites. Our primary source of water is third-party supply (i.e., the local municipal water supply); we do not withdraw from surface water or groundwater. In 2024, total water withdrawals across all sites were 149.62 million liters, a 13.82% decrease versus 2023. At the Suzhou Plant, comprehensive leak inspections and remediation reduced withdrawals from 124.72 to 102.91 million liters, a 17.49% reduction.Discharge management at each plant complies with local regulations and actual process conditions. At the Taiwan Plant, discharge volumes are compiled from the Taoyuan Pingzhen Wastewater Treatment Plant's monthly records; other plants estimate volumes based on their water-use profiles. In 2024, total discharges across the four plants were 71.85 million liters. Discharges were managed in a stable manner and continued to meet local standards, with outflows directed either to surface-water bodies or to thirdparty treatment. Water consumption reflects the net water used by each plant; in 2024 total consumption was 76.33 million liters, down 16.29% year on year.
