Air Pollution Control
Nuvoton strictly complies with government environmental regulations and references international standards, striving to continuously reduce air pollutants generated during production processes. These pollutants include volatile organic compounds (VOCs), nitrogen oxides (NOx), sulfur oxides (SOx), ammonia (NH₃), chlorine (Cl₂), hydrochloric acid (HCl), nitric acid (HNO₃), and phosphoric acid (H₃PO₄).
The company adopts source control strategies, improving processes to lower exhaust gas concentrations and emissions, and applies appropriate treatment based on the characteristics of the exhaust gases. Air pollution control systems operate 24/7 year-round, with continuous monitoring to ensure proper functioning. In addition, certified laboratories are commissioned annually for testing, and results are reported to the competent authorities. Historical test results have consistently been far superior to regulatory standards.
Air Pollution Prevention Measures
To effectively reduce air pollutant emissions, Nuvoton adopts multiple treatment technologies based on the characteristics of exhaust gases, ensuring compliance with environmental standards:
General Exhaust
Heat dissipation exhaust from equipment, which does not contain air pollutants.
Acidic and Alkaline Exhaust
Treated through scrubber tower with water washing
Organic Exhaust
Adsorbed and concentrated using a zeolite rotor, then desorbed at high temperature and incinerated
High-Boiling-Point Organic Exhaust
Processed via condensation treatment, followed by activated carbon adsorption.
