They are not just a nuisance: according to the **European Environment Agency (EEA)**, odors are among the main causes of environmental complaints near industrial plants, landfills, and waste treatment facilities. In Italy, the management of industrial odours emissions is addressed by **Legislative Decree 152/2006** and regional guidelines, while at European level the **UNI EN 13725** standard defines methods for sampling and olfactometric analysis. For companies, addressing odours emissions means not only improving air quality, but also preventing disputes, complying with emission limits, and ensuring a healthier working environment. ## Where do odours emissions come from? Odors perceived outside industrial plants originate from compounds released during chemical, biological, or thermal processes. The main groups of responsible substances include: - **VOCs (Volatile Organic Compounds)** such as aldehydes, solvents, and alcohols - **Sulfur compounds** such as hydrogen sulfide (H₂S) and mercaptans - **Nitrogen compounds** such as ammonia and amines - **Organic acids** generated by fermentation or decomposition processes These emissions are typical of many industrial and infrastructural contexts, including: - landfills and waste treatment plants - wastewater treatment facilities - chemical and pharmaceutical industries - food and feed industries - drying plants - composting facilities and intensive agriculture In all these cases, the objective is to capture gaseous pollutants and abate them before they are released into the atmosphere. ## **Solutions to eliminate odour ****emissions** Treating odours emissions requires more than simply identifying them: the compounds that generate odors must be neutralized or degraded at the source. HFiltration provides a comprehensive portfolio of technologies including [scrubbers](https://www.hfiltration.com/soluzioni/abbattimento-composti-organici-volatili-c-o-v/torre-di-lavaggio-scrubber), [biofilters](https://www.hfiltration.com/soluzioni/abbattimento-composti-organici-volatili-c-o-v/biofiltri), [activated carbon](https://www.hfiltration.com/soluzioni/abbattimento-composti-organici-volatili-c-o-v/filtri-a-carboni-attivi-cov), and [thermal oxidizers](https://www.hfiltration.com/soluzioni/abbattimento-composti-organici-volatili-c-o-v/ossidatori-termici-cov), designed to adapt to emissions of different nature, concentration, and flow rate. Each process requires a specific approach, and selecting the most effective technology depends on the type of pollutant, the industrial sector, and the emission limits that must be met. ## **Why choose HFiltration for** **odor emission ****abatement** HFiltration designs **custom-made odor abatement systems**, developed according to airflow rates, pollutant concentrations, emission limits, and the specific characteristics of each industrial process. Our industrial filtration solutions ensure high removal efficiency even for complex emissions, operational continuity, low operating costs, and seamless integration with existing plants. Correctly managing odors is not only about complying with regulations: it also helps to **maintain a positive relationship with the local area**, prevent reports from the community, and strengthen the company's reputation as a reliable and environmentally conscious company. These systems are ideal for companies looking to improve air quality, reduce environmental impact, and ensure healthier and safer working environments.   Would you like to learn more about the most effective technologies for eliminating industrial odors?

They are mixtures of volatile compounds that produce perceptible and often unpleasant odors. They can originate from chemical, biological, or thermal processes and are regulated by technical standards and environmental guidelines. - ### How can industrial odors be eliminated? Odors are eliminated by treating the substances that generate them using scrubbers, biofilters, activated carbon filters, or thermal oxidizers. The choice depends on the type and concentration of pollutants. - ### Which industries generate the most industrial odors? There are several sectors in which odorous emissions require dedicated systems to ensure compliance with regulations. These include waste treatment, wastewater treatment, the food industry, chemical industries, and composting facilities. Depending on your sector, we help you choose the most suitable solution.   - ### What technologies does HFiltration offer for odor abatement? HFiltration develops multistage scrubbers, biofilters, activated carbon systems, and combined solutions to treat complex odors. Each system is custom-designed based on production processes and emission limits.   ### SUBSCRIBE TO THE NEWSLETTER     ### We design, develop and implement systems for industrial air purification and filtration.
