Odor Control System Market Report 2025

The odor control system market size has grown strongly in recent years. It will grow from $6.08 billion in 2024 to $6.52 billion in 2025 at a compound annual growth rate (CAGR) of 7.2%. The growth observed during the historic period can be attributed to factors such as expanding industrialization, heightened awareness of environmental regulations, increased demand from wastewater treatment facilities, growing urbanization and population, and greater adoption of advanced odor control technologies.

The odor control system market size is expected to see strong growth in the next few years. It will grow to $8.51 billion in 2029 at a compound annual growth rate (CAGR) of 6.9%. The growth in the forecast period is expected to be driven by escalating environmental concerns, stricter government regulations, rising demand from the food processing sector, increased investments in wastewater management, and broader adoption of sustainable odor control solutions. Key trends during the forecast period include progress in biofiltration technologies, innovations in chemical scrubbers, the integration of IoT for real-time odor monitoring, improvements in eco-friendly odor neutralizers, and the development of modular odor control systems.

The rise in industrialization is expected to drive the growth of the odor control systems market moving forward. Industrialization is the process of shifting an economy from primarily agricultural to manufacturing and industrial-based activities. This growth is fueled by urban population increases, which in turn boost demand for infrastructure and services, leading to expanded manufacturing and industrial operations. Odor control systems aid industrialization by providing a cleaner and safer work environment, minimizing harmful emissions, and ensuring compliance with environmental regulations, thus promoting sustainable industrial development. For example, a report published by Statistics Canada in July 2023 indicated that nearly 9% of manufacturing businesses planned to expand to other locations within the same province, a figure similar to those in administrative and support, waste management, and remediation services (9.1%). Furthermore, more than 5.5% of manufacturing businesses intended to expand internationally, with comparable plans noted in arts, entertainment, and recreation (5.3%) and wholesale trade (4.5%). Consequently, the increasing demand for industrialization is propelling the growth of the odor control systems market.

Leading companies in the odor control systems market are focusing on developing advanced technologies such as biological hydrogen sulfide removal to improve efficiency, reduce environmental impact, and offer safer, chemical-free solutions for industrial and municipal wastewater treatment. Biological hydrogen sulfide removal uses natural bacteria to transform toxic hydrogen sulfide gas into harmless substances, effectively eliminating odors without chemicals. For instance, in September 2024, Aquacycl, a US-based wastewater treatment company, introduced SulfideFix, an innovative odor control product. This technology utilizes a micro-aeration process to biologically prevent sulfide emissions from wastewater tanks, effectively removing odors at their source. Industries benefiting from this technology include oil and gas, recycling, wastewater management, and large-scale food and beverage production. Its adoption addresses the critical demand for reliable odor control and sulfide emission reduction in these sectors.

In February 2025, Cleanwater1, a US-based water technology firm, acquired Integrity Municipal Systems (IMS) for an undisclosed sum. This acquisition broadens Cleanwater1’s odor control and chemical feed solution offerings, strengthens its engineered treatment system portfolio, and enhances its services for the wastewater industry. Integrity Municipal Systems (IMS) is a US-based manufacturer that specializes in odor control systems for wastewater treatment plants and sewage pump stations.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s recommendations and conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The swift increase in U.S. tariffs and the ensuing trade tensions in spring 2025 are significantly affecting the machinery sector by increasing costs for steel, hydraulic systems, and precision bearings critical components often imported from tariff-affected regions. Manufacturers of construction, agricultural, and industrial machinery now face squeezed margins, as many long-term contracts prevent immediate price adjustments. The uncertainty has also delayed investment in automation and smart machinery technologies, slowing productivity gains. To adapt, firms are accelerating local supplier development, redesigning products to use alternative materials, and leveraging predictive maintenance to extend equipment lifespans amid higher replacement costs.

An odor control system comprises a range of technologies and processes aimed at detecting, neutralizing, or eliminating unpleasant or harmful odors in industrial, commercial, or municipal settings. These systems typically employ techniques such as chemical scrubbers, activated carbon filters, biofilters, or thermal oxidizers to maintain air quality standards and improve environmental safety.

The primary categories of odor control systems are physical, chemical, and biological. Physical odor control systems involve methods that remove or mask odors through physical means such as filtration, adsorption, or oxidation without involving chemical reactions. These systems can be installed as fixed or portable units and are commonly used in waste treatment plants, the food and beverage sector, pulp and paper industry, chemical and petrochemical plants, among others.
