Water Resource Management
Starting from the sustainable use of water resources, BenQ Materials follows three main principles: water inventory, water-saving measures, and recycling and reuse. These principles extend to four strategic stages: wastewater reduction, wastewater recycling, development of new water sources, and zero wastewater discharge. Wastewater reduction and recycling are approached from four main water usage areas: domestic, process, air conditioning systems, and boiler water. The company aims to gradually improve water use efficiency and strategies. In 2023, the Taoyuan Plant introduced the ISO 46001 Water Efficiency Management System and passed the verification.
In 2023, BenQ Materials (excluding subsidiaries) had a total water intake of 342.45 million liters (ML) across all plants, a decrease of 83.47 ML compared to 2022. The total discharge of wastewater was 269.24 ML, which was directed to the sewage treatment plants in various industrial zones, a reduction of 91.38 ML compared to 2022. The water consumption was 73.21 ML, primarily used for the evaporation of cooling tower water in the chilled water system.
In 2023, the discharge rate (discharge volume/total water intake) for BenQ Materials (excluding subsidiaries) was 78.62%. If the recycled water from internal process recycling, scrubbing tower recycling, process water treatment recycling, ROR cycle recycling, wastewater treatment recycling, and air conditioning water recycling is included, the R2 (reuse rate) was 87.62%. If the recycled water from cooling towers is also included, the R1 (overall plant recycling rate) could reach 97.82%.

- Note 1: BenQ Materials uses the WRI Aqueduct water risk scenario simulation tool to analyze the geographical locations of its operational sites. In the short term, only the Suzhou Plant in China is in a high water stress risk area, accounting for approximately 16.32% of the total water intake.
- Note 2: The scope of water resource disclosure for 2023 includes BenQ Materials headquarters, Taoyuan Plant, Longke Plant, Yunke Plant, Suzhou Plant, Wuhu Plant, Sigma Medical Materials, Hailu Plant, BMC (Dormitory), BMM, and DTB.
- Note 3: The energy disclosure data for 2021-2022 has been updated (reason for update: exclusion of subsidiaries). The disclosed data does not include subsidiaries (Weipu, Shuocheng, and Jingjie), which are expected to complete third-party verification and be included in the disclosure scope in 2024.
