Water saving measures and performance

Water conservation efforts at FENC focus on reducing water loss caused by the wind drift and evaporation at the cooling tower. With production management and control, the Company aims to increase the concentration of recirculating cooling water, reduce water consumption and construct water recycling and reuse systems to achieve water conservation.The Company’s production business formulates water management plan (including water recycling system) coverage rate of 100%.

Water Recycling and Reuse

The water recycled in 2023 is down by 8% from 2022. The main contributing factor is decreased production at the Petrochemical Business, which led to a 15% decline in the use of cooling water. The FENC-wide water recycling rate remains at 98%.

Avid Support for Governmental Policies

1. Switch to smart meter to provide real-time data on water resources.
   FENC supports water conservation policies enacted by the government with strong efforts to reduce water consumption. The Company implements water management systems at all production sites, adopts water-conserving technologies and reuses water resources to achieve the water conservation targets set by the government.
2. Commit to including domestic reclaimed water as source of water withdrawal.
   OPTC signed the recycled water use contract with the Taoyuan City Government for a three-phase project to utilize reclaimed water, and the completion of phase one is expected in 2025. The reclaimed water will go through the UF membrane and RO, reaching a quality surpassing that of tap water and meeting industrial water standards. Phase one will produce 40,000 kiloliters of reclaimed water daily, and approximately 15,000 kiloliters will be utilized by OPTC. This project is the exemplification of FENC’s commitment to water conservation and its answer to the governmental policy on the circular economy and water reclamation.
