Consistently innovates and upgrades wastewater treatment facilities to reduce wastewater discharge.

Measures for Effluent Management

Effluents Management Policy

Effluent source management
The discharge of oil agents and surfactants is minimized by modifying and optimizing the production process.
Treatment efficiency management
Gradually phase out old equipment, regularly replace filter membranes, and perform routine maintenance to prevent equipment failures in wastewater treatment facilities that could cause water quality issues and environmental impact.
Environmental impact management
Continuously establish low-noise, low-odor, and low-pollution effluent treatment facilities, fully enhance effluent recycling rates, and implement resource recycling and reuse. Use online monitoring instruments to measure and monitor the concentration of Mixed Liquor Suspended Solids (MLSS) in the wastewater treatment system. Provide real-time sludge concentration data to facilitate operator adjustments and ensure stable system operation.

FENC has a comprehensive set of guidelines and operating procedures established to address effluent discharge. The Company conducts pollutant treatment with regular self-evaluation and testing that target an array of pollutants. Among them, those regulated by the local government are prioritized for treatment to keep the water quality in line with regulatory standards. Permits are obtained from the government authority prior to discharging the effluent into water bodies as stipulated by law, and the recycled effluent is for internal use only.

Since February 1, 2023, water users in Taiwan with over 9,000 KL in monthly consumption have been imposed a water conservation charge during the dry season. After the requirement went into effect, FENC paid a yearly charge that amounted to approximately 0.1% of the total revenues generated by its production sites in Taiwan, which does not constitute a material financial impact. FENC will minimize its water conservation charge by continuing to implement water conservation measures, utilizing reclaimed water and increasing the water recycling rate.

Water Discharge in 2024

Water Discharge per Unit of Production

Unit: kiloliter / metric ton of production

Note: FEAZ, FEAV and FENV are not included.

The total effluent is down by 18% in 2024 compared with the previous year, and the effluent per unit of production is cut by 14%. The Company will install additional effluent recycling and reuse systems to increase water efficiency per unit of production.
