AJ Bush G4 Bioenergy Project (Revoked)

The AJ Bush G4 Bioenergy Project (Revoked) was an industrial wastewater treatment project located at the AJ Bush & Sons rendering facility in Bromelton, approximately 5km west of Beaudesert and 60km south of Brisbane in Queensland. Registered in March 2017, the project operated within the Scenic Rim region, an area traditionally known for beef cattle grazing, dairying, and cropping, though the specific project site sits within a dedicated State Development Area for heavy industry.

The project operated under the Carbon Credits (Carbon Farming Initiative-Domestic, Commercial and Industrial Wastewater) Methodology Determination 2015. This methodology involves installing anaerobic digesters to treat industrial effluent, in this case, the wastewater from animal by-product rendering, which replaces deep open anaerobic lagoons that would otherwise release significant amounts of methane into the atmosphere. The "G4" project was specifically designed to capture this biogas (methane) and combust it for energy generation, thereby reducing greenhouse gas emissions while powering the facility's boilers.

The Bromelton and Beaudesert region is characterized by a sub-tropical climate with summer-dominant rainfall averaging around 850mm to 950mm annually. The local terrain features the Logan River floodplain, typically consisting of fertile alluvial soils and heavy cracking clays (Vertosols) known as "black earth," which are common in the valleys of the Scenic Rim.

Notable for its corporate history, the project was originally developed as an expansion to an existing bioenergy facility by ReNu Energy (formerly Geodynamics). The "G4" expansion involved the construction of a new covered anaerobic lagoon. The proponent listed, Janus Electric Holdings Limited, appears to be the corporate evolution of the entity that managed the project, led by executives who pivoted from bioenergy to electric heavy vehicle technology. The project was revoked in March 2020 following the termination of its carbon abatement contract, likely coinciding with the transfer of the bioenergy assets back to the site owner, AJ Bush & Sons, or a restructuring of the proponent's business focus.
