Air Pollution Control

TTY presents no effort on the air pollution issue. In the year 2021, our two main manufacturing sites adopted source classification to minimize air pollutants during the manufacturing process. Treatment technology at multiple sections has helped elevate the processing performance of the terminal preventive facility. The annual inspection on air pollutant discharge as well as implementation meant that the maintenance and training were put in place to make certain that pollutants going into the air fall within the criteria of the “Stationary Pollution Source Air Pollutant Emissions Standards” - with the pollutant concentration superior to existing regulation.
Taking control from the beginning works best 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, the pollutants are classified based on their nature such as dust, organic solvents, and odors. Then the local scrubber is treated through washing, then activated carbon absorbers or bag-type dust collectors process the remaining exhaust before they are released into the air. The pollutant concentration is now in accordance with the relevant regulations. The sectional treatment is a perfect, all-direction solution to making air emission treatment more effective.
