OdourCollect is an innovative citizen science platform developed to enhance the monitoring and management of odour pollution, especially in complex settings with multiple emission sources.

   By actively involving local communities in the detection and reporting of odour events, the platform produces collaborative, real-time odour maps that are integrated with meteorological and regulatory information. This participatory methodology not only improves the characterisation and localisation of odour impacts but also facilitates compliance with the UNE 77270:2023 standard. Consequently, OdourCollect serves as an effective tool for environmental consultants, public authorities, and citizens to comprehensively manage odour-related environmental challenges.

   The Jagüel Wastewater Treatment Plant in Punta del Este, Uruguay, underwent an odor control improvement plan ahead of a major renovation.

    A study by Ambiente et Odora measured H₂S emissions, modeled odor dispersion with CALPUFF, and identified key sources. Corrective actions included improved ventilation in centrifuge rooms, replacement of biofilters with granular activated carbon filters, and dosing ferric chloride into the slurry. These measures effectively reduced odors during the summer season, with no reported complaints.
