Environmental Management
Continuously to introduce new technology on air pollution prevention and control, and examines existing facilities and production process regularly. To ensure regulatory compliance and help reach reduction targets.
Air Pollution Management Guidelines and Measures
Air pollutants emitted in 2022 dropped by 7% from the previous year while air pollutants emitted per unit of production increased by 3%. The main contributing factor to the increase comes from decreased production. FENC aims to strengthen its ongoing efforts in improving air pollution prevention and control with enhanced equipment and facility monitoring.

| Note: 1. Only emitted gases are listed. 2. Particle pollutants include suspended particle matters (PM), dust and smoke. 3. The collected data covers 3 categories, actual measured value, annualized sampling value and estimates. In 2022, actual measured values are collected at Hsinpu Chemical Fiber Plant (NOx, SOx, particle pollutants), Kuanyin Chemical Fiber Plant (NOx, SOx, particle pollutants), FEFC (NOx and SOx), polyester plant of FEPV, OPTC Plant 2, OPSC (NOx and SOx), WHFE, Kuanyin Dyeing and Finishing Plant, FEIW, FEDZ, FEAZ, FEAV and FENV. Annualized sampling values are collected from OPSC (VOCs), FEIS, OTIZ and the textile plant of FEPV. Estimates are collected from OPSC Plant 1, Hsinpu Chemical Fiber Plant (VOCs), Kuanyin Chemical Fiber Plant (VOCs), OGM, FEFC (particle pollutants), Hukou Mill, APG Polytech and FIGP. 4. Data on hazardous air pollutants (HAP) are collected at APG Polytech in the U.S. and FIGP in Japan. The 3 HAPs identified at APG Polytech are ethylene glycol, acetaldehyde and 1,4-Dioxane, which are regulated by U.S. Environmental Protection Agency. Acetaldehyde, which is on the list of HAPs regulated in Japan, is identified at FIGP. 5. Data collection on air pollutant management accounts for 100% of FENC 21 production sites. |
FENC consistently introduces technology that enhances air pollution prevention and control, and examines existing facilities and production process regularly. The boilers and exhaust pipes are also inspected on a regular basis to ensure regulatory compliance and reach reduction targets.
System Establishment and Management
Incorporation of Innovation Technology and Facility
- To reduce air pollutants, Hsinpu Chemical Fiber Plant installed the selective catalytic reduction (SCR) equipment, which utilizes catalysts to reduce the NOx and ammonia mixture to nitrogen and water. The equipment removes 80% of the NOx in the water slurry boiler. All 6 sets of equipment has completed in 2022.
- FEDZ installed low NOx burners for the boilers, which reduced NOx emissions by 66%.
- Kuanyin Chemical Fiber Plant replaced the heavy oil boilers with natural gas boilers in November 2022 in hopes of reducing the emission of NOx, SOx and particulate pollutants.
Value Chain Collaboration
FENC engages customers and the supply chain and provides air pollution training. For instance, WHFE conveys the Company philosophy on environmental protection through the procurement process. Each year, the plant conducts approximately two on-site visits to evaluate the suppliers. The evaluation team consists of auditors, site engineers and quality control managers. In 2022, nine suppliers signed the air pollution environmental control commitment, which represent 70% of non-raw material procurement.
Avid Support for Governmental Policies
As stipulated in the governmental announcement, Public and Private Premises Requiring Dedicated Air Pollution Control Personnel and Dedicated Health Risk Assessment Personnel Placement, the area where terephthalic acid production takes place at Plant 1 of OPTC is considered a premise requiring designated personnel from the first announcement. On January 5, 2022, the plant added one dedicated personnel and one deputy. Due to the amendment of the Regulations Governing Severe Air Quality Deterioration Announcements and Emergency Prevention and Control on March 3, 2022 and the decrease in overall air pollutant emissions at Plant 1 of OPTC, the plant is no longer regulated under the Prevention and Control Plan for Air Quality Deterioration of All Levels at Public and Private Premises. The boiler production at Plant 2 of OPTC, however, is regulated under said plan and must submit an air pollutant reduction plan. The plant has prepared a prevention and control plan for approval the completed the first drill.
The City of Shanghai, mainland China updated HJ1230-2021 Volatile Organic Compound Leakage, Detection and Repair in Industrial Enterprises, which stipulates the inspection methods for a leak, detection and repair (LDAR) program as well as the selection criteria for inspected locations. FEIS conducts LDAR inspections annually and the 2022 inspection as well as the selection of inspection points were performed in accordance with the updated regulation.
