Meteorological Eulerian models like WRF, combined with Gaussian and Lagrangian dispersion models, are commonly used to assess odor impact from emissions measured by dynamic olfactometry, with four specific models (PMSS, GRAL, CALMET/CALPUFF, and AERMOD) tested for performance evaluation.

   The choice of model must be tailored to the specific environmental conditions, source characteristics and project objectives, so no one model is universally superior to others. This nuanced understanding of model applicability is vital to the effectiveness of odor management strategies in various environments, including urban and industrial settings.

   With the new odour standard for swine facilities in Chile, Maxagro and the industry face the challenge of advancing towards sustainable production and managing community expectations.

   Despite technological investments that have reduced odours by over 75%, the perception of low-level odours can still lead to complaints. Maxagro actively works with the community to improve understanding and social well-being.
