Hobart McRobies Gully Landfill Gas Abatement Facility

Hobart McRobies Gully Landfill Gas Abatement Facility is a landfill gas to electricity generation project located at McRobies Gully in South Hobart, approximately 3km west of the Hobart CBD in Tasmania. It was registered in August 2013 and operates across a roughly 20-hectare municipal waste management centre. The region surrounding the site is known for a mix of urban residential development and the dense, forested bushland of the adjacent Mount Wellington national park.

Landfill gas electricity generation projects involve capturing methane emissions that are produced by decomposing legacy and non-legacy organic waste. This captured gas is combusted in generators to produce electricity, effectively destroying the methane, which has a much higher global warming potential than carbon dioxide, while providing a continuous renewable energy source.

The South Hobart area is considered to have a temperate maritime climate with reliable, moderate rainfall. The natural soils in the gullies around Mount Wellington generally consist of podzolic and clay loams, though the project site itself is heavily modified with many metres of compacted landfill waste covering the underlying bedrock of the Derwent Rift fault system.

This project has successfully transitioned from a revoked legacy method and is currently operated by the proponent LMS Energy Pty Ltd. In February 2023, the project completed a major Commonwealth carbon abatement contract (CAC354956), successfully delivering 84,000 Australian Carbon Credit Units (ACCUs). Due to the landfill's unique location bordering a national park, the site requires careful management by the local council to prevent leachate runoff into the nearby Hobart Rivulet and to deter scavenging by native wildlife.
