Flue Gas Treatment Systems Market Forecast Highlighting Growth From $78.34 Billion To $96.45 Billion
The flue gas treatment systems market size has seen strong growth in recent years. It is anticipated to increase from $74.31 billion in 2025 to $78.34 billion in 2026, achieving a compound annual growth rate (CAGR) of 5.4%. The expansion observed in the historic period can be attributed to the growth of waste-to-energy facilities, the enforcement of stricter air emission regulations, the proliferation of industrial combustion processes, increasing investments in pollution control infrastructure, and a heightened emphasis on environmental compliance.
The flue gas treatment systems market is poised for significant expansion in the coming years, projected to reach $96.45 billion by 2030, exhibiting a compound annual growth rate (CAGR) of 5.3%. This growth during the forecast period is attributed to several factors, including the increasing adoption of next-generation emission control systems, the expansion of industrial decarbonization initiatives, rising investments in retrofitting aging plants, a growing demand for mercury and dioxin control solutions, and the increasing integration of digital monitoring systems. Major trends expected within this period encompass the wider deployment of advanced emission control technologies, the rising integration of multi-pollutant treatment systems, a growing embrace of energy-efficient flue gas cleaning solutions, the expansion of modular and scalable treatment configurations, and an enhanced focus on regulatory compliance systems.

Flue Gas Treatment Systems Market Growth Drivers: What Factors Are Accelerating Expansion?
The growth of the flue gas treatment systems market is projected to be stimulated by the expansion of liquefied natural gas production in the coming years. Combustion processes are commonly found in LNG production facilities, and the burning of natural gas can release emissions like nitrogen oxides (NOx) and carbon dioxide (CO2). These emissions can be effectively reduced and managed using flue gas treatment systems, which helps industries adhere to environmental regulations. Liquefied Natural Gas (LNG) is natural gas that has been chilled to approximately -162 degrees Celsius (-260 degrees Fahrenheit), causing it to transition from a gaseous to a liquid state. Small liquid natural gas distribution stations are also required to install compact, high-efficiency cryocoolers to reliquefy boil-off gas in the liquid natural gas tank. As an illustration, in January 2024, the US Energy Information Administration (EIA), a US-based federal statistical agency, reported that US LNG exports rose by 12% in 2023, reaching an average of 11.9 billion cubic feet per day, making the United States the world’s largest LNG exporter. Consequently, the increasing liquefied natural gas production is a significant factor driving the flue gas treatment systems market.

Flue Gas Treatment Systems Market Trends Reshaping Industry Growth
Major companies operating in the flue gas treatment systems market are focusing on developing innovative solutions, such as compact emission control devices, to help customers meet genset emission regulations and reduce environmental impact by cutting harmful exhaust emissions. A compact emission control device is a specialized system designed to significantly reduce harmful exhaust emissions from engines or industrial processes, typically characterized by its small size and high efficiency in filtering pollutants like particulate matter and nitrogen oxides. For instance, in September 2024, Cummins India Limited, an India-based manufacturer of diesel and natural gas engines, launched the Retrofit Aftertreatment System (RAS). This system reduces Particulate Matter (PM), Carbon Monoxide (CO), and Hydrocarbon (HC) emissions from genset exhaust by up to 90%, while being compact and cost-efficient. Its Diesel Oxidation Catalyst and Particulate Filter technology ensures compliance with stringent emission regulations, supporting cleaner air and lower maintenance costs.
