The paper, entitled “Sustainable Farms from a Biogenic Co2 Source: The CO₂-MPS Strategy”, has been developed by A. Gueddari, Á. García-Alaminos, C. Alonso, J. Canales-Vázquez and S. García-Yuste.

This paper proposes a novel strategy to increase pig farmhouses’ sustainability.

Swine farming faces unprecedented challenges in meeting the growing demand to feed an increasing population. To do so, these farms contribute significantly to producing approximately 35 % of the world’s NH₃ emissions, a highly harmful air pollutant. In response to this critical environmental issue, the CO₂ Management Pig Slurry Strategy (CO₂-MPS) proposes an innovative solution to mitigate NH₃ emissions by leveraging the biogenic CO₂ produced within pig farmhouses. This groundbreaking Carbon Dioxide Utilization (CDU) approach based on utilizing this biogenic CO₂ to form a protective blanket over pig manure lagoons promises the reduction of over 8 million metric tons of NH₃ emissions annually. Such NH₃ emissions are well-documented initiators of Particulate Matter, particularly PM2.5, highlighting the potential positive impact on air quality of this strategy. In addition, implementing the CO₂-MPS strategy would lead to the generation of environmentally friendly fertilizers.
