Biogas is a renewable source of energy that can be produced and captured from piggery effluent and can be used as an energy source to generate electricity, for heating and cooling, or can be purified into biomethane for higher-end users. Biogas improves social license due to odour reduction and sustainable farming practices.

To date, biogas use on-farm has been considered most economical for larger piggeries (1000+ sows farrow-to finish). This project sought to explore the biogas at a medium sized piggery, by conducting a real case study on a 535-sow farrow-to-finish piggery in Victoria, Australia. This project determines the real feasibility, costs, and benefits associated with a biogas system on a medium-sized piggery as well as provides alternative uses for biogas, allowing for more flexible systems. Additionally, the project explored three hypothetical scenarios for biogas use and provided estimated costs and payback periods for these.
