Market Growth Factors

The major factor driving the growth of the odor control system market is rapid industrialization around the world. Oil refining, chemical synthesis, and agriculture processing industries require better air quality. The installation of these systems in hospitals, transportation hubs, and public spaces has driven the market. The development of hybrid odor control systems, providing a multi-stage air filtration using chemical and biological adsorption, has also driven the market.

The market is being driven by increasingly stringent environmental regulations. The United States Environmental Protection Agency, the European Environment Agency, China's Ministry of Ecology and Environment, and others have tightened air quality standards. For example, the European Union's revised Ambient Air Quality Directive, published in December 2024, seeks to halve the thresholds for fine particulate matter by 2050. The tighter legislation has provided an incentive for high-performance odor control units to be installed within industrial areas, in a bid to avoid fines or litigation, as well as to improve worker and community safety.

Odor control is becoming more of a concern as the world becomes more urbanized. According to the United Nations, urban areas are projected to house 70% of the world's population by 2050, causing industries and wastewater treatment plants to be placed closer to residential areas. Odor control technologies are also likely to be inducted into the mainstream of public health protection. Further, investments in membrane technology and water reuse are likely to drive the market across industries.

Market Segmentation

Analysis by System Type:

  • Biological Odor Control System

Analysis by End Use Industry:

  • Chemical and Petrochemicals
  • Mining and Metals
  • Power and Energy: Holding about 27.6% of the market in 2024, this sector demands extensive odor control due to emissions from power plants, oil refineries, and gas processing. Advanced technologies such as chemical scrubbers, biofilters, and activated carbon systems are employed to meet regulatory standards and handle sulfur and nitrogen oxides.
  • Oil Refineries
  • Others

Regional Insights

Asia Pacific dominated the odor control system market in 2024 with a share exceeding 42.4%. This dominance is fueled by rapid industrialization, strict environmental regulations, and escalating investments in wastewater treatment and air quality management in major countries like China, Japan, and India. The region is also experiencing growth in petrochemical demand and renewable energy projects, further increasing the necessity for effective odor control solutions.
