TTY strived every effort to reduce air pollution. In year 2022, two main manufacturing sites adopted source classification to minimize air pollutants during manufacturing processes. Treatment technology at multiple sections has helped elevate the processing performance of the terminal preventive facility. Annual air pollutant discharge inspections and implementation have resulted in maintenance and training put in place to ensure that pollutants fall within or are superior to the criteria of the Stationary Pollution Source Air Pollutant Emissions Standards. In year 2022, the 2 manufacturing sites of Lioudu and Chungli factories discharged particle pollutants of PM 6.17kg, SO2 12.97kg, and NOX 310.24kg in total.
Air Pollutant Control Process
Taking control from the beginning is the most effective way to minimize pollutants. In TTY, the "effective minimization on emission sources and enhanced treatment at the terminal preventive facility" is our current practice. Starting at the source in phase I, pollutants are classified based on their nature, such as dust, organic, solvents, and odors. The local scrubber is then treated through washing, following which activated carbon absorbers or bag-type dust collectors process the remaining emissions before they are released into the air. The pollutant concentration now complies with the relevant regulations. The sectional treatment is a perfect, all-direction solution to making air emission treatment more effective.
