The circular economy is an industrial system designed for recovery and regeneration to replace “end of life” with “recovery" in order to turn waste into resources and thereby achieve waste reduction. By constantly implementing the circular economy, we implement water conservation and drainage reduction through improvement programs to reclaim and recycle valuable water resources for reuse and set the annual water conservation target at “1%". The actual conservation in 2024 was 6.20%. The boundary of water resource and effluent management is the Kaohsiung Plant, with data coverage of 100%.

In terms of water stress distributions, based on the water stress by country in the ‘Aqueduct Water Risk Atlas’ published by the World Resources Institute (WRI), the water stress of Taiwan falls at the low to medium level, with water stress at 10-20%.

According to the 2023 water resources statistics published in the Water Resources Agency Register Statistical Report, MOEA, the water consumption of Kaohsiung City was 927,279.141 ML, including 349,667.41 ML of water for domestic use and public use, 242,403.883 ML of water for industrial use, and 335,197.848 ML of water for agricultural use. The 2024 total water withdrawal of Kaohsiung Plant was 938.423 ML, accounting for about 0.1% of Kaohsiung City’s total water consumption. Kaohsiung Plant withdraws water mainly from tap water supplied by the Pingding Waterworks and Cheng Ching Lake Waterworks for product production, equipment cooling, boiler, domestic use of employees, and other uses. In 2024, due to a decrease in annual production, the water withdrawal decreased by about 31.1 ML to 938.423 ML compare to 2023.
