The 16th International Bioenergy Congress witnessed an important advance in the biogas industry thanks to Laura Escudero, R&D technician at Kerbest, who shared a practical case: the Psychrophilic anaerobic digestion of pig manure at Avicogan farm, located in the province of Ávila, Castilla y León.
Kerbest's Avicogan farm housed a psychrophilic anaerobic digester, the result of a cooperative project aimed at reducing emissions from manure management. This digester, which operated with a mixture of raw slurry and solid slurry, achieved reduce emissions into the atmosphere by an impressive 80%.
The process was “effective,” maintaining room temperature and a retention time of 55 to 62 days. Additionally, a flare was installed to burn the gas produced, ensuring that the environmental impact was significantly reduced.
In her presentation, Laura Escudero highlighted that as the composition of the biogas was analyzed, the presence of oxygen gradually decreased, which demonstrated the stabilization of the digester. Despite these successes, the Kerbest technician acknowledged that there is still work to do, such as improving digester insulation, seeking additional resources, and carrying out digester inoculation.
Laura Escudero's presentation at the 16th International Bioenergy Congress highlighted a innovative and effective approach to reduce emissions in the agricultural industry, demonstrating Kerbest's commitment to sustainability and research. The success of this project is a clear example of how bioenergy can contribute to the well-being of the environment and society in general.
