Water Resources Management
Climate change is altering hydrological patterns and increasing the risk of compound disasters, making water resource management increasingly important. Asia Cement uses its water risk management policy to identify potential impacts, promote water recycling and reuse, and set performance indicators and adaptation measures.
Water Resource Risk Assessment
According to the World Resources Institute’s Aqueduct Water Risk Atlas, the 2025 water-stress risk for all Asia Cement operating sites in Taiwan was assessed as Low-Medium (10–20%). Under the pessimistic scenario, the risk remains Low-Medium in both 2030 and 2050. None of the sites is located in a water-stressed area.
Asia Cement’s water risk management process covers risk and opportunity identification, materiality assessment, financial impact analysis, response measures, and cost estimation. A financial impact greater than NT$10 million is defined as substantive. The assessment periods are short term (2026), medium term (2027–2030), and long term (2031–2035). Potential financial impacts include increased operating expenses and reduced revenue.
Asia Cement Water Use Indicators and Targets
In 2025, Asia Cement’s water recycling rate reached 88%, exceeding its 85% target. Water-use intensity was 0.673 metric tons of water withdrawal per metric ton of cementitious materials, down 21% from 2024. Net freshwater consumption, excluding municipal water supply, was 2,127 thousand metric tons, down 18%; wastewater discharge was 206 thousand metric tons, down 3%. All four reported indicators met their 2025 targets. Starting in 2026, the water recycling rate target will be adjusted to 83% following a review of plant water-use requirements.
Asia Cement’s information of water use
Asia Cement mainly withdraws groundwater, while its subsidiaries mainly use tap water. All withdrawn water is freshwater (TDS ≤ 1,000 mg/L), used mainly for cooling and the operation of machinery and equipment. The figures below distinguish Asia Cement from its subsidiaries.
