This study identifies the most significant odor compounds in pig and poultry farms to better understand odor issues and develop effective management strategies

   A literature review and compound analysis revealed common substances like methanethiol and trimethylamine, as well as specific ones like hydrogen sulfide in pig farms and acetaldehyde in poultry farms. The study emphasizes the importance of proper odor management on farms to mitigate negative impacts on health and the environment.

The Odour Group (GO) of the Spanish Association of Water Supply and Sanitation (AEAS) is a very active group within this association. This group has been working for several years on the results of a survey designed to assess the cost of odour management in WWTPs and sanitation networks serving more than 10,000 equivalent inhabitants in Spain. Finally, after multiple coordination meetings over the past year, this much-awaited study on the state of odour management in Spain's urban wastewater infrastructure has been published.

The aim of this study, based on a similar one carried out by WEF a few years ago, was to evaluate the different aspects related to the cost of odour management. This evaluation was carried out through the analysis of 400 responses received from operators and managers of plants, in which they were asked for data such as the odour control systems used, operational and maintenance costs, the economic cost of managing odour-related incidents, and design costs.
