JBS Beef City Biogas to Boiler Fuel Substitution

JBS Beef City Biogas to Boiler Fuel Substitution is an Industrial and Commercial Emissions Reduction project located at 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 JBS processing facility's footprint.

Industrial and Commercial Emissions Reduction projects involve reducing energy emissions by upgrading, removing, or substituting existing emissions-producing equipment. Standard requirements mandate modifying energy sources or replacing equipment to reduce reliance on emissions-heavy fuel and electricity, in this case, switching from natural gas to renewable biogas.

The Darling Downs region is well known for intensive agriculture, including broadacre grain cropping, grazing, and large livestock feedlots. The area generally experiences a moderate, subtropical rainfall and features highly fertile, deep cracking clay soils known as vertosols.

Project activities include boiler upgrades, fuel switching, process heat modifications, control systems upgrades, and waste heat capture and re-use. The project relies on covered anaerobic lagoons to capture naturally occurring biogas from the site's wastewater emissions. The renewable gas is then pumped through delivery pipelines to a boiler, substituting natural gas to produce hot water for the meat processing plant.

An interesting note is that the JBS Beef City site, originally built in 1974, recently celebrated its 50th anniversary of continuous operations. Delivered in partnership with Energy360 and AGL, the new bioenergy system produces up to 10,000 cubic metres of renewable biogas per day. This eliminates the equivalent of approximately 34,000 tonnes of carbon dioxide emissions and saves an estimated $1.2 million in natural gas expenses annually. Additionally, the project underwent a method variation on 5 September 2023, officially transitioning from the 2015 Industrial Electricity and Fuel Efficiency method to the 2021 Industrial and Commercial Emissions Reduction determination.
