Water Management
LITEON managed water resources based on ISO 14001 Environmental Management System. Water consumption at LITEON plants was sourced from tap water and used primarily for employees' daily needs and plant equipment. The reduction plans include auditing the significant water use and water efficiency and reduction training. In terms of the drainage system, LITEON ensured that the quality of effluent meets the requirements of local environmental protection agencies and does not cause an environmental burden. A small amount of industrial wastewater is treated by the wastewater treatment facilities inside the plants (by methods such as sedimentation or chemical coagulation) and discharged when the treated wastewater meets the local regulatory requirements. All wastewater produced is either properly treated or discharged to sewage treatment plants. LITEON made sure that the water discharge had no significant impact on the water body.
Water Risk Assessment
Areas with higher risk in LITEON's water resource management are identified using external tools and internal evalsuation methods. External tools used to analyze the potential impact of main locationss of operations on water resources include WRI tools and the scenario RCP 8.5 in the IPCC guidelines; internal evalsuation is conducted via on-site evalsuations, which identify higher risk areas in LITEON's water resource management including Tianjin, Vietnam, Thailand, and India. LITEON improves the water quality in areas with higher risk, to lower the burden on the air conditioning system, improving equipment efficiency and reducing water evaporation.
Water Management Performance
LITEON uses 2020 as the baseline year and sets an absolute reduction target of 6% for water resources in 2023. In terms of management, LITEON uses a management system to monitor the water consumption of major operating sites worldwide. We compared the water withdrawal information of the same months in the previous year, to maintain reasonable use of water resources and track water conservation results. Total water consumption in 2023 was 2,066,626 m3 (18.5% lower than in 2020) and the intensity was 15.07 m3 NTD million of revenue (18.44% lower than in 2020).
LITEON promoted the improvement of water quality and water conservation measures. These measures included implementing the effective management of wastewater, inspecting water-saving appliances, strengthening leakage prevention, improving the recovery rate of water used in production, and reducing the water escape rate of cooling towers. LITEON also strengthens daily management practices such as training. We exceeded expectations by achieving the water resource reduction target set in 2021. In 2024, we set an absolute water resource reduction target of 6% in 2026 using 2023 as the baseline.
Water Reuse
The cooling water in the chiller is recycled and reused, and a small amount of process-cutting water is well-treated and recovered into the water system. In addition, the factory's domestic water and the rainfall water are also recycled. The water from drinking fountains is recycled and reused as a water source for flushing toilets. We collected the rainfall water to incorporate into our daily water use including flushing the toilet, etc. The total reclaimed water volume in 2023 was 0.277 Mm3 (276,932 m3 ), a decrease of 13,878 (approximately 4.77%) compared with 2022. LITEON will continue to improve water recycling and reuse to reduce its water consumption and environmental impact.
