2021 Environmental Protection Targets and Management Programs

Policy Goals Program Effectiveness
Zero Emission Reduce the fugitive emissions of VOCs of equipment/component and measured leakage rate <0.5% Enhancement of equipment/component self-management, periodic inspection and review of maintenance and repair progress, identification and improvement of equipment/component with a high leakage rate, reduction of the quantity equipment/component or replacement of equipment/component with a lower leakage rate or without a shaft, and enhancement of inspection for equipment/component with a high leakage rate and more motions. 2021 measured VOCs leakage rate 0.038%
Zero Emission Improve process equipment and pipelines to reduce the fugitive emissions of VOCs.
  1. Construction and improvement of process emission pipelines
  2. Process equipment improvement
  1. Improved the process equipment and pipelines of 2 assembly lines to reduce the fugitive emissions of VOCs. Improvement of other assembly lines will continue in 2022.
  2. Added 3 tanker unloading arms and completed the improvement of 6 catalyst mixing tanks to effectively reduce the fugitive emissions of VOCs.
Zero Emission Reduced GHG emissions by 1,004 tCO2e Five plant electricity conservation projects In 2021, electricity was saved up to 1,972,419kWh accumulatively and emissions were reduced up to 1,004 tCO2e.
Zero Emission Reduce water discharge by 5,280 MT Continuous monitoring and reclamation of effluents In 2021, a total of 10,986 MT of water was reclaimed from the effluent reclamation system.
Zero Pollution Prevent equipment corrosion from causing the leakage of organic substances Equipment cooler renewal project Completed the renewal project to ensure no leakage due to equipment corrosion.
Zero Pollution Improve effluent water quality to 60% effluent standard (COD<60 mg/L) Effluent Quality Control Enhancement In 2021, effluent COD was 14.4 mg/L in H1 and 25.5 mg/L in H2
Zero Pollution Complete the construction of the block control and wastewater treatment equipment to prevent wastewater anomalies from occurrence.
  1. Improvement of the operation of wastewater treatment plants.
  2. Effective block and control abnormal wastewater leakage
  1. In 2021, the COD, SS, and grease in effluents complied with the discharge standards.
  2. In March 2021, new major separator valves and sampling points were added to effectively block and control wastewater at the source.
Zero Pollution Prevent environmental contamination caused by plastic resin pellet leakage Prevention and management of plastic resin pellet leakage
  1. Enhanced publicity of dust zone cleaning and tanker loading area cleaning.
  2. Ensured that the unloading pipe is inserted in the inlet and surroundings are covered with dust screens before unloading in the tanker loading operating process to prevent materials from splashing.
  3. Revised and released the WI-KHB-810-51 work instructions of the Finished Product Section and included the plastic leakage management system.
  4. Inventoried the leakage prevention and management measures of plastic resin pellets at the processing area and recovered 12.87MT of plastic resin pellets in 2021.

Environmental Expenditures

Our environmental management costs include the cost for environmental management activities, environmental-protection-related personnel expenses, and equipment maintenance cost. In 2021, we will actively promote the improvement of process safety equipment, waste treatment, and the professional training of environmental protection personnel. In 2021, the total amount of environmental expenditures increased by 16.8% over 2020 to about NT$135.67 million

Note 1: The cost for environmental management activities includes the fees for air pollution control, water pollution prevention, waste disposal, noise pollution prevention, management of toxic and concerned chemical substances, industrial safety improvement, depreciation of fixed assets and others (e.g., cleaning and mowing).

Note 2: Environmental-protection-related personnel expenses include personnel expenses and environmental protection-related training fees.

Note 3: Equipment maintenance cost includes the fees of environmental-related equipment and the fees for equipment maintenance.
