'Wyemo Biogas Project

Wyemo Biogas Project is an animal effluent management project located approximately 25km west of Warwick in the Darling Downs region of Queensland. It was registered in May 2022, and while the exact project area size is not published, it is situated in a rural area known for broadacre cropping, cattle grazing, and intensive livestock farming, such as large-scale piggeries.

Animal effluent management projects involve collecting and combusting methane generated from decomposing animal waste (such as piggery effluent) at an emissions destruction treatment facility. This standard process destroys the methane, a potent greenhouse gas, before it can be released into the atmosphere, thereby generating carbon credits.

The Darling Downs region typically experiences a moderate, summer-dominant rainfall climate. The local soils are highly fertile, generally consisting of deep alluvial clay loams, cracking clays (vertosols), and basalt profiles.

An interesting note about this project is its proponent, Cefn Energy Pty Ltd, which is part of the CEFN group. Established in 1940, CEFN is an independent, family-owned agricultural business and one of Australia's largest pork producers. The biogas project was set up to manage the environmental impact of the piggery by mitigating methane emissions from its effluent lagoons. In June 2026, the project recorded a methodology variation, updating to Compilation No. 2 of the 2019 Animal Effluent Management method.
