Water Resource Management

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.



 

At present, each plant in Taiwan has wastewater recovery and treatment facilities within the plant. Wastewater discharged from the plants is 100% connected to the sewer systems of the industrial park wastewater treatment plants where the plants are located for subsequent wastewater treatment. Each industrial park wastewater treatment plant has established standards for influent limits, and wastewater must be discharged in accordance with these standards. Domestic wastewater from the Suzhou Plant is discharged into the municipal sewer network and centrally treated by the municipal wastewater treatment center. Process wastewater from the Wuhu Plant consists of wastewater from coating roller cleaning. After flocculation, sedimentation, and filtration, it is combined with domestic sewage treated through septic tanks and discharged into the sewer network. In 2025, no water quality abnormalities occurred at any plant.

In 2025, BenQ Materials, including subsidiaries, had total water withdrawal of 834.68 megaliters (ML), an increase of 477.42 ML compared to 2024. In 2025, total water discharge, namely wastewater discharge, was 673.81 ML, discharged into the wastewater treatment plants of each industrial park. This represented an increase of 397.33 ML compared to 2024. Water consumption was 160.86 ML, mainly attributable to evaporative water use by the cooling towers of the chilled water system.

In 2025, BenQ Materials, including subsidiaries, had a total discharge rate, calculated as water discharge divided by total water withdrawal, of 81.39%. When recycled water from in-process recovery, scrubber recovery, process water treatment and reuse, ROR circulation and reuse, wastewater treatment recovery, and air-conditioning water recovery is included, R2, or the reuse rate, was 72.39%. When recycled water from cooling towers is further included, R1, or the plant-wide recycling rate, reached 93.45%.

Annual water resource utilization intensity and utilization overview

• Note 1: BenQ Materials uses the WRI Aqueduct water resource scenario simulation tool to analyze the geographic locations of its operating sites. In the short term, only the Suzhou Plant in mainland China and the Vietnam Plant are located in areas with high water stress risk, accounting for approximately 13.28% of overall water withdrawal.
• Note 2: The 2025 water resource disclosure scope includes BenQ Materials Headquarters, including the Taoyuan Plant, Hailu Plant, and BMC No. 28; Longtan Plant; Yunlin Plant, including Yunlin Plant, Yunlin Plant I, and Yunlin Manufacturing Plant III; Manufacturing Plant I; Suzhou Plant, including BMS, BMM, and DTB; Wuhu Plant; and subsidiaries GeneJet, Cenefom, and Web-Pro (including the Vietnam Plant)
• Note 3: Water resource disclosure data for 2021 to 2025 has been updated. The disclosed data includes subsidiaries GeneJet, Cenefom, and Web-Pro (including the Vietnam Plant), which completed third-party verification in 2025 and were included in the disclosure scope.
