Waste Gas Treatment Market: Overview

Waste gas treatment refers to the range of procedures and technologies used for removing harmful contaminants from waste gases. It deals with solutions such as filters and scrubbers to remove harmful elements from industrial exhaust gases before they are released into the environment. Some of the most widely used treatments include photochemical reactors, thermal oxidation, and filtration. Waste incineration, smelting & refining, power generation, chemical processing, and Platinum Group Metals (PGMs) refining are some of the leading reasons for the growing release of waste gas. The global demand for waste gas treatment is expected to grow due to the rising rate of air pollution reported worldwide. The severe impact of the release of untreated waste gas on living organisms and the ecological system will further influence industry revenue in the coming years. In addition to this, rising regulatory pressure and market innovation will help generate new growth opportunities for industry players. The market may face growth limitations due to the high cost of treatment and maintenance requirements.

Waste Gas Treatment Market: Dynamics

Growth Drivers

How will rising air pollution levels influence the waste gas treatment market revenue?

The global waste gas treatment market is expected to witness high growth due to the rising rate of air pollution levels across the globe. While there are different reasons that contribute to the surge in air pollution rates, untreated gases released from industrial facilities remain a prominent contributor to the decline in air quality across the globe.

According to the United Nations Environment Program (UNEP), more than 80% of the urban African population lives in areas with air quality levels above the World Health Organization (WHO) limits. Around 8 million people across the globe died due to poor air quality in 2023. Lack of access to high-quality air is a leading reason for mortality behind medical conditions such as cancer and cardiovascular diseases. These statistics compel industries to ensure that waste gas is treated before it is released into the environment, subsequently driving demand for effective treatment methods.

Rapid industrialization across the global landscape is expected to fuel market revenue in the long run

One of the major growth propellers for waste gas treatment solutions is the rapid industrialization observed worldwide. As per the United Nations Industrial Development Organization (UNIDO), around 2.3% of industrial growth was recorded in 2023, with waste management, manufacturing, electricity, and mining emerging as prominent industries. The surge in the demand for goods & commodities, along with increased government support and technological advancements, are some of the leading reasons for the increased industrialization rate.

For instance, in December 2025, Sika, one of the world’s leading specialty chemicals companies, commenced operations at its new facility in Haines City, Florida, USA, thereby expanding its presence in the Southeastern United States. The ongoing industrialization in developing parts of the world will work in favor of the global waste gas treatment market.

Restraints

Why will high cost of investment and maintenance limit growth in the waste gas treatment market?

The global industry for waste gas treatment is expected to be restricted due to the high cost of initial investment associated with the industry. According to industry research, the average cost of large industrial waste gas treatment systems, such as thermal oxidizers and wet scrubbers, can range from USD 1,60,000 to USD 3,00,000 or more, depending on the device's overall features.

Additionally, these technologies require frequent repair and maintenance, adding to the overall cost of ownership. The expenses associated with establishing an effective waste gas treatment infrastructure will limit the entry of new players in the industry and also reduce profit margins for existing players.

Opportunities

Ongoing innovations and advancements are reported in the market to offer new growth opportunities

The global waste gas treatment market is expected to generate growth opportunities due to the rising investments in innovations and advancements to improve the efficiency of the procedures. In December 2025, the Massachusetts Institute of Technology (MIT) announced that its chemical engineers had developed a novel mechanism for capturing carbon dioxide from industrial plants. The new method leverages a chemical called tris(hydroxymethyl)aminomethane (tris). The chemical can be used to stabilize the solution pH used in capturing carbon dioxide. The system will then be allowed to capture more gas at low temperatures. The method has shown applications across prominent industries such as cement, pharmaceuticals, and fertilizers.

In December 2025, ABB, a global technology company, announced the launch of a single device analyzer that measures the volume of gas contaminants. The device is called Sensi+ NG with the ability to measure trace levels of carbon dioxide, hydrogen sulfide, and water vapor. The 4-in-1 device is expected to act as an addition to real-time monitoring devices, subsequently helping enhance the efficiency of waste gas treatment processes.

Challenges

Why will the high energy dependence of the procedures challenge the waste gas treatment market?

The global waste gas treatment industry market is expected to be challenged by the high energy dependence of the treatments. According to industry analysis, most waste gas treatment solutions, such as wet scrubbers, demand high water and energy consumption. This raises questions over treatment sustainability, especially in the backdrop of the growing energy crisis reported worldwide. Additionally, insufficient space to install large-scale waste gas treatment infrastructure may exacerbate the industry's existing growth barriers.
