Abstract

The study assessed greenhouse gas (GHG) emissions from a 3,600-pig farm in Lien Minh commune, Ninh Binh province, using IPCC (2006) guidelines. The farm uses industrial feed and treats waste with a biogas system and composting. Results showed total emissions of 706.1 tons CO2e/year, with CH4 making up over 95 % due to anaerobic digestion. N2O emissions came mainly from using post-biogas waste for irrigation or composting. Key emission factors included biogas recovery efficiency, waste treatment methods, and farm management practices.
