JBS Beef City Wastewater Biogas Emissions Reduction

JBS Beef City Wastewater Biogas Emissions Reduction is an industrial wastewater project located at the JBS Beef City facility in Purrawunda, approximately 35km west of Toowoomba on the Darling Downs in Queensland. It was registered in January 2022 and covers an unspecified area within the integrated feedlot and processing facility's footprint.

Domestic, commercial, and industrial wastewater projects involve capturing the biogas generated during the biological treatment of wastewater. By replacing deep open anaerobic lagoons with covered anaerobic digesters, naturally occurring methane is captured rather than being vented into the atmosphere. For this specific project, the collected biogas is subsequently combusted using a boiler to generate production heat for the meat processing plant.

The surrounding Darling Downs region is well known for its intensive agriculture, particularly broadacre grain cropping and livestock feedlots. The area generally experiences a moderate, subtropical rainfall climate and is characterised by highly fertile, deep cracking clay soils, often referred to as vertosols.

This bioenergy upgrade was delivered in partnership with Energy360 and AGL, producing up to 10,000 cubic metres of renewable biogas per day (roughly 64 terajoules annually). This circular wastewater treatment system effectively reduces the site's reliance on natural gas and eliminates the equivalent of approximately 34,000 tonnes of carbon dioxide emissions each year. An interesting historical note about the proponent property is that JBS Beef City recently celebrated 50 years of operation, having been originally constructed in 1974 as one of Australia's first large-scale integrated feedlot and abattoir operations. The project's methodology determination was updated in March 2025 to Compilation No. 3.
