Wasleys Biomethane Project

Wasleys Biomethane Project is an animal effluent management project located at the SunPork piggery in Wasleys, a rural agricultural town situated just north of Adelaide in South Australia. It was registered on December 11, 2025, by LMS Energy Pty Ltd. While the exact project area in hectares is not publicly defined, the facility is designed to operate on a commercial scale directly integrated into the piggery's footprint.

Animal effluent management projects under the ACCU scheme involve capturing and combusting methane generated from the anaerobic decomposition of agricultural animal waste. By treating the effluent in covered anaerobic lagoons or digesters, these projects prevent potent greenhouse gases from entering the atmosphere.

The Wasleys region is known for its intensive agricultural land use, particularly cereal cropping and livestock farming operations like piggeries. The area experiences a Mediterranean climate with hot, dry summers and cool, relatively wet winters, receiving moderate rainfall of around 400-500mm annually. The regional landscape consists of undulating hills and plains, with soil types predominantly featuring red-brown earths, clay-loams, and sandy mallee soils.

This project treats animal effluent using solid separation and post-diversion treatment at an emissions avoidance facility. Rather than simply combusting the captured methane, the project uses advanced membrane technology to clean and upgrade the biogas into pipeline-quality biomethane.

Notably, this is Australia's first commercial-scale agricultural renewable gas facility, delivered in partnership between LMS Energy and Australian pork producer SunPork. Backed by $10 million in funding from the Australian Renewable Energy Agency (ARENA), the $24.1 million facility is designed to generate approximately 40 terajoules (TJ) of renewable natural gas (RNG) per year. This RNG is then injected directly into the South Australian natural gas distribution network to be used as a natural gas substitute, which is enough to meet the energy needs of around 2,000 South Australian homes.
