Air Pollution Control

Management Approaches

TCC strictly controls process air emissions to ensure compliance with government emission standards and to reduce environmental impact.
The cement plants have undergone environmental protection equipment upgrades, resulting in a year-on-year decrease in pollutant emissions.

Note 1: TCC employs advanced technologies over air emissions control, and all emission concentrations remain well below regulatory standards.

Note 2: As the particulate collection equipment do not replace every year, and the marginal efficiency of the equipment gradually declines during its service life, minor fluctuations in particulate emissions are observed between replacement intervals.
