Enviropower Investments Goondiwindi Piggery Project

Enviropower Investments Goondiwindi Piggery Project is an agricultural methane destruction project located approximately 12km north of Goondiwindi in the Darling Downs region of southern Queensland. It was registered in March 2014. While the specific project area size is undisclosed, the project operates within a region highly regarded for its intensive agricultural land use, including broadacre cropping of cotton and grains, beef cattle grazing, and commercial piggeries. The Goondiwindi area is situated in a semi-arid to subtropical climatic zone with a summer-dominant average annual rainfall of approximately 600-620mm. The local landscape features fertile Vertosols, which are cracking clay soils known for their high moisture-holding capacity.

Methane destruction projects in piggeries involve capturing biogas emissions from manure waste and combusting it to prevent the release of methane, a potent greenhouse gas, into the atmosphere. Under the Carbon Credits (Destruction of Methane Generated from Manure in Piggeries-1.1) Methodology, this project collects effluent in covered anaerobic lagoons and combusts the methane component. This process often includes flaring or utilizing the biogas to generate electricity, which reduces the site's reliance on grid power while earning Australian Carbon Credit Units (ACCUs).

Originally registered under an engineered biodigester methodology, the project varied its method in August 2014 to the current covered lagoon approach. The current project proponent, SP Northern Farming Piggeries Pty Ltd, is a subsidiary of the SunPork Group, one of Australia's largest pork producers. In April 2015, the project successfully secured a carbon abatement contract with the Australian Government, and records indicate that this contract (CAC336810) was officially completed in 2020.
