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. |
- Construction and improvement of process emission pipelines
- Process equipment improvement
|
- 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.
- Added 3 tanker unloading arms and completed the improvement of 6 catalyst mixing tanks to effectively reduce the fugitive emissions of VOCs.

Prevent environmental contamination caused by plastic resin pellet leakage |
Prevention and management of plastic resin pellet leakage
|
- Enhanced publicity of dust zone cleaning and tanker loading area cleaning.
- 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.
- Revised and released the WI-KHB-810-51 work instructions of the Finished Product Section and included the plastic leakage management system.
- 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.
