Odor Control System Market Size & Trends

The global odor control system market size was valued at USD 5.74 billion in 2024 and is expected to grow at a CAGR of 5.9% from 2025 to 2030. Increasing demand to reduce malodors among various end-use industries is the key factor driving the odor control system industry growth. Moreover, odors are generated during various stages of the manufacturing process, such as synthesis of chemical compounds, oil refining, microbial decomposition of organic compounds, and processing of agricultural products.

The treatment of odor owing to its impact on the environment is a major concern among end-use industries, which is further bolstering the market growth. The primary objective of installing odor control systems in various manufacturing industries is to improve the quality of the air. Odor control systems are used for air purification, source treatment, and odor neutralization.

Odor control systems are critical as manufacturing plants emit foul odor in the atmosphere, thus deteriorating the air quality. The foul odor generated during various operations can also hamper productivity of the manufacturing plants. Thus, owing to the above-mentioned concerns, the odor control system industry is expected to witness significant growth during the forecast period.

Furthermore, rapid industrialization in a number of developing and developed countries has substantially contributed to the pollution of the environment. Thus, the increase in the number of manufacturing facilities has resulted in the unregulated emission of gases and chemicals into the atmosphere. This combination of different gases and chemicals leads to the emission of malodor into the surrounding environment. However, growing awareness among end-use industries pertaining to the use of odor control systems is further presenting opportunities for market growth.

The high cost of the odor control systems and surging operating costs are anticipated to hamper the adoption of odor control systems. However, stringent government regulations and policies imposed on the end-use industries for odor control and management are likely to drive the market during the forecast period. The government of several countries has implemented certain standards for the emission of gases in the environment. Thus, the manufacturing facilities have to adhere to the laws formulated for smooth execution of their processes.
