Methane Mitigation:
Livestock Methane

Dairy cattle and swine farm operations produce large volumes of manure as liquids and slurries that are typically stored in large lagoons where anaerobic decomposition produces biogas containing upwards of 70% methane. Globally, manure management contributed about four percent of total anthropogenic methane emissions in 2010, nearly half of which was generated in the United States. Manure management through the use of biogas recovery and control systems can reduce methane emissions and generate GHG emission reduction credits. A biogas recovery and control system is an anaerobic digester that captures and combusts methane-rich biogas to produce electricity, heat, or hot water. Biogas recovery and control systems not only serve to mitigate GHG emissions and produce clean energy but also improve air and water quality, reduce odors, improve nutrient management, and promote sustainable environmental development.
