Water Resources Management
Consistently innovates and upgrades wastewater treatment facilities to reduce wastewater discharge.
Effluent Management Regulations
FENC established the Water Pollution Management Regulations, which has gone into effect after the Board approval. According to the regulations, the heads of the responsible units are tasked with establishing response strategies, action plans, management indicators and targets and overseeing progress tracking and management. Implementation progress is periodically reported to senior executives and the Board. In the event of violations against effluent quality regulations related to the operational status of water pollution treatment equipment, anomalies and improvement plans at production sites, while implementing remedial and improvement measures prescribed by the authorities, FENC also reinforces preventive management, including the enhancement of training.

In the event of wastewater pollution or abnormal discharge, emergency management protocols are activated to contain the pollution source and prevent the escalation of impacts. Each incident is investigated methodically to identify the root cause, the scope of impact and responsibilities. The findings then dictate the formulation and implementation of specific corrective and preventive measures, such as optimizing operational procedures, increasing monitoring frequency, upgrading equipment and reinforcing personnel training, to keep similar incidents from reoccurring.
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 2025

In 2025, total effluent discharge decreased by 8% compared with 2024. However, an uptick of 3% is observed in effluent discharge per unit of production compared with the previous year, which is the result of structural adjustments in production capacity and changes in management conditions for cooling water and dyeing and finishing processes. FENC has optimized water management while installing and expanding effluent recycling and reuse systems to boost the water efficiency per unit of production. These measures aim to continue reducing the water footprint to help FENC implement water recycling and management with higher efficiency.
Effluents Treatment and Final Discharge Destination
Business | Production Site | Effluents Treatment and Final Discharge Destination |
Petrochemical | OPTC | OPTC wastewater goes through biotreatment, including anaerobic and high-efficiency aeration treatments. Once reaching the sewage connection standards, the wastewater is discharged into the sewage system operational center in Kuanyin Industrial Park and finally discharged into Shulin River. |
Polyester | Hsinpu Chemical Fiber Plant | Wastewater goes through biotreatment internally. Once reaching effluent standards, it is discharged into Fengshan River. |
Kuanyin Chemical Fiber Plant | Wastewater goes through biotreatment internally. Once reaching effluent standards, it is discharged into Shulin River. | |
FEFC | Wastewater goes through biotreatment (contact oxidation) and sedimentation internally. Once the water reaches the effluent standards, it is discharged into Shulin River. | |
OGM | Plant 1: The wastewater is treated at the effluent treatment facility within OGM. Once reaching the sewage connection standards, the wastewater is discharged into the sewage system operational center in Kuanyin Industrial Park and eventually discharged into Shulin River. Plant 2: The wastewater is treated at the effluent treatment facility within OGM. Once reaching the sewage connection standards, the wastewater is discharged into the sewage system operational center in Taoyuan Science and Industrial Park and eventually discharged into Dajue River. | |
FEIS | Wastewater is treated internally until reaching the required standards, and then discharged through the municipal pipelines to Fengxian District East Wastewater Treatment Plant. Once fully treated, the wastewater is discharged into Hangzhou Bay. | |
WHFE | Treated in the internal wastewater treatment facility first, the wastewater then goes through the municipal wastewater treatment facility. Once fully treated, it is discharged into the Yangtze River. | |
FEPV | Wastewater is treated internally until reaching the required standards (through online testing), and then discharged into ecological pond no. 1 in Bau Bang Industrial Park. Once fully treated, the water is discharged to Thị Tính River. | |
FIGP | Tokyo Plant: Wastewater is treated internally until reaching the required standards and then discharged to Tone River. Himeji Plant: Wastewater is treated internally until reaching the required standards and then discharged to Yumesaki River. | |
APG Polytech | Wastewater is treated internally until reaching the required standards and then discharged to Ohio River. | |
PFEM | Wastewater is treated internally until reaching the required standards, discharged to the drainage system of Senai Industrial Estate 3, and eventually discharged into Skudai River. | |
Textile | Kuanyin Dyeing and Finishing Plant | Wastewater is treated in house, discharged to the wastewater treatment plant in the industrial park for further treatment, and then discharged into Shulin River. |

| Note: 1. On-site wastewater treatment is designed to reach the standards of secondary treatment, which aims to remove substances and materials that have remained in the water, or are dissolved or suspended in it. 2. Effluent discharge from Hsinpu Chemical Fiber Plant, Kuanyin Chemical Fiber Plant, FEFC and FEIS includes wastewater from the manufacturing process, domestic use, cooling tower and cleaning water. Effluent discharge from OGM, WHEF, the knitting and dyeing plant of OTIZ, the polyester plant of FEPV and APG Polytech includes wastewater from the manufacturing process, domestic use and laboratory. Effluent discharge from PFEM includes wastewater from the manufacturing process, domestic use and cooling tower. Effluent discharge from Kuanyin Dyeing and Finishing Plant, the tech textiles plant of OTIZ, FENV and FIGP includes wastewater from the manufacturing process and domestic use. Effluent discharge from OPTC includes wastewater from the manufacturing process and cooling tower. Domestic wastewater is the only source of effluent discharge at FEIW, FEAZ and FEAV, and manufacturing process is the only source at the knitting and dyeing plant of FEPV. 3. There is no significant impact caused by the effluent on water bodies and adjacent habitats. 4. Minimum wastewater discharge standards have been established at all production sites in accordance with local regulations and industry characteristics. 5.
