Odor Control System Market Report 2026

The odor control system market size has grown strongly in recent years. It will grow from $6.52 billion in 2025 to $6.98 billion in 2026 at a compound annual growth rate (CAGR) of 7.1%. The growth in the historic period can be attributed to industrial air quality regulations, expansion of wastewater treatment facilities, food processing odor management needs, chemical industry emissions control, municipal waste management growth.

The odor control system market size is expected to see strong growth in the next few years. It will grow to $9.08 billion in 2030 at a compound annual growth rate (CAGR) of 6.8%. The growth in the forecast period can be attributed to stricter environmental regulations, urbanization driven odor mitigation demand, adoption of smart odor monitoring, expansion of industrial manufacturing, sustainability focused infrastructure investments. Major trends in the forecast period include adoption of advanced biofiltration systems, integration of real time odor monitoring, growth of portable odor control solutions, increased use of activated carbon technologies, rising demand for regulatory compliance 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.
