The agro-industrial sector generates emissions of gases such as methane, ammonia, and hydrogen sulfide, which affect air quality and contribute to climate change.

   The Ubiproc® system employs biological filtration through microbial biofilms in closed organic waste pits, combined with real-time gas monitoring to optimize management. Field trials demonstrated maximum removal efficiencies of 87% for ammonia and 70% for hydrogen sulfide, with consistently stable average performance throughout the operational period.

   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.
