Water Resource Risk Management |
|
Key indicators for water resource risk management include water supply quantity and environmental discharge water quality. Kinsus identifies water risks within its factory areas and establishes comprehensive emergency response procedures. It also expands regional water resource sources and promotes the reuse of recycled water. |

Water Resource Usage |
|
A comparison of water consumption and wafer input from 2023 to 2025: |
| Year | 2023 | 2024 | 2025 |
|
Total Water Consumption (million liters) |
5,454 | 6,543 | 7,790 |
|
Total Wafer Production (million wafers) |
4,718 | 6,392 | 7,087 |
|
Unit Water Consumption per Unit Output (liters/wafer)
|
1,156.08 | 1,023.67 | 1,099.15 |
Note：
● In 2024, with the commencement of operations at the Xing-Feng II and Youth Factories,
the unit water consumption per production capacity decreased to 1,023.67 liters per piece.
● In 2025, water consumption per unit of production capacity increased slightly to 1,099.15 liters per piece due to
water usage associated with the trial operation of Youth Factory II.

Water Saving Measures |
|
Kinsus continuously pursues innovation with a primary focus on ongoing improvement. Through water-saving measures, we aim to optimize water usage while actively identifying new opportunities for conservation. The Company also enhances its recycled water systems to reclaim water used in production lines, thereby improving the overall water recovery rate. Based on the Company’s 2025 operational performance, the annual water recycling rate remained above 5.5%. Going forward, Kinsus will continue to implement water conservation projects and increase the water recycling rate by 1% annually starting in 2026, with the goal of achieving a 10% water recycling rate by 2030. |
| Year | 2023 | 2024 | 2025 |
| Water Recycling Rate | 5.4% | 7.5% | 9.7% |
|
● The source of recycled water is RO regeneration wastewater and process recycled water. The recycling rate is calculated as the total amount of recycled water in each plant divided by the total water consumption. ● In 2023, the Youth Factory was added to the reporting scope. As the plant had not yet commenced production, the volume of recycled water was relatively low, resulting in a decline in the recycling rate for that year. Following increases in production capacity, the recycling rate improved to 9.7% in 2024 and remained at the same level in 2025. starting in 2026, with targets of 6.5% in 2026, 7.5% in 2027, 8.5% in 2028, and 9.5% in 2029, ultimately achieving a water recycling rate of 10% by 2030. |
