Flue Gas Desulfurization (FGD) Systems Market Set to Reach USD 34.1 Billion by 2032, Driven by Emission Norms and Industrial Growth
Market Size
- 2024 Estimated Value: USD 22.46 Billion
- 2025 Projection: USD 23.34 Billion
- 2032 Forecast: USD 34.1 Billion
- CAGR: Ranges from approximately 3.9% to 6.3%
Overview
Flue Gas Desulfurization (FGD) systems are critical emission control technologies that eliminate sulfur dioxide (SO₂) from exhaust gases in industrial processes, especially in coal-fired power plants. These systems help industries comply with environmental regulations, improve air quality, and generate by-products like gypsum used in construction. With rising industrialization and stringent environmental policies, demand for both wet and dry FGD technologies is growing rapidly across power generation, cement, chemical, metal, and mining sectors.
