NAWMA Landfill Gas Project

NAWMA Landfill Gas Project is an electricity generation from landfill gas project located at the Uleybury Landfill (also referred to as the Uleybury Balefill), approximately 4km east of Elizabeth and 30km north-northeast of Adelaide in South Australia. Registered in December 2013, the project operates on the site of a former quartzite quarry. The general land use in the surrounding area is a mix of rural residential properties, grazing land, and nearby viticulture operations.

Electricity generation from landfill gas projects involve the installation of a network of vertical and horizontal wells to capture methane gas naturally produced by decomposing organic waste. Instead of allowing this potent greenhouse gas to vent into the atmosphere, it is extracted and combusted in a gas generator. This standard process safely destroys the methane, reducing the facility's carbon equivalent emissions, while producing renewable electricity that is exported to the local power grid.

The Uleybury region sits in the foothills of the Mount Lofty Ranges and experiences a Mediterranean climate characterised by hot, dry summers and cool, wet winters with moderate rainfall. The local landscape typically features soils classified as red-brown earths or clay loams over limestone and quartzite.

Operating under legacy and non-legacy waste methods, the project transitioned from a revoked Carbon Farming Initiative (CFI) method. A uniquely interesting feature of this facility is its past operation as a "balefill", where general waste was first compacted into high-density 1.5-tonne bales at a dedicated transfer station before being transported to Uleybury for burial, significantly optimising space and minimising litter. Additionally, in October 2017, the site partnered with proponent LMS Energy to become one of Australia's first waste facilities to integrate landfill gas generation with an adjacent solar farm. This pioneering hybrid renewable energy park channels solar energy alongside methane gas to supply baseload power to the South Australian grid. While the Uleybury landfill officially closed to new waste in June 2025, the gas extraction and power generation activities continue to abate historical emissions.
