Susco Biogas Project

Susco Biogas Project is an animal effluent management project located at the 'Susco' breeder farm in the Leyburn and Ellangowan region, approximately 50km southwest of Clifton on the Darling Downs in Queensland. Registered in September 2025, the project is operated by Cefn Energy Pty Ltd, a subsidiary of the prominent Australian family-owned pork producer, Cefn Pty Ltd. The facility is situated within a region heavily utilized for intensive agriculture, mixed cropping, and grazing, benefiting from the fertile black cracking clay soils typical of the Darling Downs. The area generally experiences a sub-tropical climate with moderate, summer-dominant rainfall.

The project operates under the Carbon Credits (Carbon Farming Initiative, Animal Effluent Management) Methodology Determination 2019. This methodology incentivizes the reduction of greenhouse gas emissions by changing how agricultural operations manage manure. Standard requirements involve diverting effluent that would otherwise release methane in open anaerobic ponds into a treatment system, such as a covered lagoon or engineered digester, that captures the gas. The captured methane is then combusted, either via a flare or an electricity generation engine, converting it into less potent carbon dioxide and often generating renewable energy for on-site use.

Cefn Pty Ltd has a history of integrating renewable energy into their operations, having previously registered the Wyemo Biogas Project for their feed mill and other farming operations. The Susco farm specifically serves as a conventional breeder unit, and this project likely represents an expansion of their sustainability infrastructure to cover emissions from this specific site's intensive piggery operations.
