Low Cost Options for Reducing Effluent Pond Methane

Abstract

Technology is available for the mitigation of pond methane emissions through biogas capture using impermeable covers and energy recovery. The high capital cost has limited the application of this technology from mid to large sized pig farms. This report reviews the current understanding and advances in low cost options for pond methane reduction that may be economically attractive to the smaller farm systems. Promising mitigation options will be identified for further research and assessment.
