AWMC Seminar Program: Solid-phase anaerobic treatment of livestock manure residues

Solid-phase anaerobic treatment of livestock manure residues: Shao Dong Yap

Abstract: Livestock industries in Australia and elsewhere in the world produce increasing amounts of solid manure residues on-farm. In Australia, typically these residues are stockpiled for passive composting prior to land application. Key concerns are uncontrolled greenhouse gas (GHG) emissions (N2O and CH4), pest propagation, dust, odour and potential land and water contamination via nutrient leaching and run-off. Treatment of solid manure residues with anaerobic digestion (AD) technology offers significant advantages over conventional stockpiling, including renewable energy generation in the form of biogas and mobilizing nutrients for subsequent recovery. However, the complexity and cost of AD technology currently limits its adoption on-farm, especially in Australia. This PhD aims to understand leachbeds as a potential anaerobic technology option for solid manure residues, in order to optimise processing of solid manure residues into biogas for use on-farm in agriculture.
