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.

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 is highly notable as it is Australia's first commercial-scale agricultural renewable gas facility. Delivered in partnership between LMS Energy and Australian pork producer SunPork, the project goes beyond simply combusting methane; it uses advanced membrane technology to clean and upgrade the captured biogas into pipeline-quality biomethane, or renewable natural gas (RNG). This RNG is then injected directly into the South Australian natural gas distribution network to be used as a natural gas substitute. 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 RNG per year, which is enough to meet the energy needs of around 2,000 South Australian homes.
