Additives for low-cost emissions reduction in piggeries

This project tests and validates chemical additives to reduce fugitive methane from piggery manure/effluent. This is important for the Australian pork sector, representing as much as 60% of overall supply chain emissions, and alternative solutions are currently cost-prohibitive for a large proportion of the sector. The project carries out laboratory validation experiments, pilot testing, and field testing at a piggery, and also performs measurements to ensure that chemical additives do not exacerbate effluent odour or have adverse effects on soil and crops when effluent is land applied for beneficial reuse.
