As concerns around climate change, industrial emissions, and urban air quality intensify, Air Pollution Control Systems (APCS) have emerged as critical infrastructure worldwide. These technologies — including scrubbers, catalytic converters, and electrostatic precipitators — are designed to remove harmful pollutants from industrial and urban emissions.
The global air pollution control systems market is expected to reach a value of $152.1 Billion by 2032, at a CAGR of 6.7% (2024–2032).
Here’s a snapshot of the leading companies shaping this industry.
