The upsurge in construction and reconstruction activities is anticipated to drive the expansion of the flue gas treatment systems market. These endeavors encompass a wide spectrum of tasks involved in erecting, renovating, or equipping structures, roads, or related facilities. Flue gas treatment systems play a pivotal role in construction by curtailing emissions from processes like cement production, known to discharge approximately one ton of carbon dioxide into the environment. For instance, in 2022, the United States Census Bureau reported a significant increase in construction spending, estimated at $1.76 trillion in June 2022 compared to $1.62 trillion in June 2021. Over the first six months of 2022, construction spending surged by 10.7% to $848.2 billion, up from $766 billion for the same period in 2021. Hence, heightened construction and renovation undertakings are fueling the growth of the flue gas treatment systems market.

The amplification of liquefied natural gas (LNG) production is poised to elevate the flue gas treatment systems market. LNG production sites often involve combustion processes that yield emissions like nitrogen oxides (NOx) and carbon dioxide (CO2). Flue gas treatment systems are instrumental in curbing and regulating these emissions, aiding the industry in adhering to environmental standards. The rise in LNG production mandates the installation of efficient flue gas treatment systems, particularly in liquefaction plants, to manage combustion-related emissions. The U.S. Energy Information Administration revealed that the United States became the world's leading LNG exporter in the first half of 2022, with a 12% surge in LNG shipments compared to the second half of 2021. This surge underscores the pivotal role of flue gas treatment systems amid the burgeoning LNG production, thereby propelling market growth.

Major companies in the flue gas treatment systems market are concentrating on creating innovative solutions, such as compact emission control devices, to assist customers in complying with genset emission regulations and minimizing environmental impact by reducing harmful exhaust emissions. A compact emission control device is a specialized system designed to significantly diminish 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 example, in September 2024, Cummins India Limited, an India-based manufacturer of diesel and natural gas engines, introduced 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 maintaining a compact and cost-efficient design. Its Diesel Oxidation Catalyst and Particulate Filter technology ensure compliance with stringent emission regulations, promoting cleaner air and lower maintenance costs.

Major companies in the flue gas treatment systems market are prioritizing strategic collaborations to maintain their market position. A strategic collaboration involves a partnership or cooperative agreement between two or more entities - such as companies, organizations, or individuals - aimed at achieving mutual objectives that align with their strategic goals. For example, in September 2023, Andritz, an Austrian global company specializing in providing technologies and solutions across various industries, teamed up with Skellefteå Kraft, a Sweden-based power company, to supply a flue gas treatment system for the company’s renewable power plant. As part of this collaboration, Andritz is replacing the existing electrostatic precipitator (ESP) in the biomass boiler with an ESP equipped with a switched integrated rectifier (SIR). The primary goal of this initiative is to significantly lower emissions and reduce power consumption compared to the previous system. The new ESP will be installed using the existing steel support structure, thereby streamlining construction efforts and accelerating the project timeline. This initiative highlights Andritz's commitment to environmental responsibility and its focus on enhancing the efficiency of biomass power generation.
