Developments in emissions reduction from livestock production wastewater (effluent)

Abstract: Manure management emissions contribute an estimated 7% of Australia’s agricultural greenhouse gas emissions. Fugitive methane from effluent storage is a major portion of these emissions and is a logical target for reduction efforts. This talk will provide an overview of approaches to reduce manure management methane, including biogas for energy recovery, emissions avoidance by manure separation, and developments of low-cost manure additives, and short hydraulic retention time systems. Opportunities, limitations, and suggested further research are outlined.
