Water Stewardship & Pollution Control
The Company recognizes the importance of water resources for stable production in the chemical industry and views water resource management as the core of business continuity planning. We focus not only on reduction but also on strengthening supply resilience through early warning and recovery. Water resource management covers two main priorities: water recovery and water withdrawal management.
▍WRI Aqueduct Water Risk Assessment & High-Risk Zone Management
- According to the risk assessment conducted using the World Resources Institute (WRI) Aqueduct Water Risk Atlas, Everlight Suzhou is located in a water-stressed area, where water is primarily used for domestic and production purposes. Therefore, we actively enhance water recycling rates through standardized management to reduce reliance on water resources.
- In 2025, water withdrawal at Everlight Suzhou dropped to 56.6 ML (a 9.4% YoY reduction). Through standardized operations and drought-period dispatching plans, we ensure our operations do not compete with local communities for water, fulfilling our corporate citizenship responsibility.
▍Water Resource Circulation & Drought Community Mutual Good
- All withdrawal sources are freshwater (TDS ≤ 1,000mg/L). Total withdrawal in 2025 was 634.0 ML, within the target (872 ML). Sources include groundwater, tap water, and industrial water.
- Planning considers government policy, company development, industry shifts, and community needs. Opening groundwater intake points for neighbors during dry periods realizes the community spirit of SDG 6 (Clean Water and Sanitation).
Optimize processes for fixed water loads during low-production periods to maintain efficiency regardlessof scale.
2025 Water Withdrawal at Plant Sites (By Source)
▍Disclosure
Total withdrawal was 634.0 ML, significantly below the 872 ML target, showing excellent management of dependency. Water Recovery R2 was 90.3%, affected by major process maintenance. Though slightly below the 92% benchmark, a PDCA project has started to optimize parameters for 2026. Total recovery and circulation reached 5,907.4 ML, equivalent to 2,362 standar d swimming pools.
Note 1: According to the standard swimming pool dimensions (50m × 25m × 2m) announced by the Chinese Taipei Swimming Association, the water capacity is approximately 2.5 million li ters (ML). Therefore, the water volume is converted as 5,907.4 ML ÷ 2.5 ML.
Historical Water Resource Management Indicators and Target Achievement Status
Practicing Indicator Management: Introducing Unit Product Water Consumption
Formally introduced into monitoring in 2025. Result: 18.7 (10³ liters / ton). The rise from 2024 is due to new boiler equipment increasing water use.Action Plan
Optimize processes for fixed water loads during low-production periods to maintain efficiency regardless of scale.
