Inkerman Landfill Gas Abatement Project

The Inkerman Landfill Gas Abatement Project is a landfill gas capture operation located at the Inkerman Landfill, approximately 15km southeast of Port Wakefield and 85km north-northwest of Adelaide in South Australia. Registered in July 2015, the project is operated by Waste Management Pacific (S.A.) Pty Limited, a subsidiary of the major waste management company Cleanaway. The facility serves as a significant waste disposal site for the region, surrounded largely by agricultural land used for cereal cropping and grazing.

The project operates under the Carbon Credits (Carbon Farming Initiative, Landfill Gas) Methodology Determination 2015. This methodology incentivizes the installation and operation of gas collection systems to capture methane generated by decomposing organic waste. By capturing this gas and combusting it, typically through flaring or electricity generation engines, the project converts potent methane into carbon dioxide, significantly reducing the global warming potential of the emissions. This specific project transitioned from an earlier "CFI" legacy waste method and continues to abate emissions from both legacy and non-legacy waste streams.

The Inkerman region experiences a semi-arid to Mediterranean climate, characterized by hot, dry summers and cool, moderate rainfall in winter, averaging around 300-400mm annually. The local landscape is defined by the Adelaide Plains' typical soil profiles, often consisting of calcareous sandy loams (Calcarosols) and red-brown earths suitable for the surrounding agricultural activities. Notably, the landfill itself has been the subject of significant environmental updates, including recent approvals to accept and safely contain PFAS-contaminated waste, highlighting its role as a specialized infrastructure asset in South Australia.
