Banksia Landfill Gas Abatement Project

Banksia Landfill Gas Abatement Project is a landfill gas abatement project located at Banksia Road in Dardanup (Crooked Brook), approximately 15 kilometres southeast of Bunbury in Western Australia. It was registered on July 16, 2015. While the exact carbon project area is officially listed as unknown, the overarching landfill facility covers an area of approximately 54.5 hectares.

Landfill gas abatement projects operate under specialized waste methodologies and involve capturing the methane-rich gas generated by decomposing organic matter within a landfill. Once captured through a network of pipes and wells, this gas is combusted via flares or engines. This standard requirement securely destroys methane, a highly potent greenhouse gas, converting it into less harmful carbon dioxide, thereby significantly reducing the site's overall global warming potential and earning carbon credits.

The Dardanup region on the Swan Coastal Plain is characterized by a mix of diverse rural land uses, notably dairy and beef cattle grazing, broadacre agriculture, and forestry plantations. The area experiences a Mediterranean climate generally classified within a high rainfall zone, historically averaging nearly 900mm of annual rainfall. Local environmental conditions feature a varied soil profile predominantly consisting of loamy earths, sandy duplexes, and gravelly clay soils.

This project features a unique operational history, having successfully transitioned from an earlier revoked 'CFI method' to newer 2015 methodological determinations, allowing it to continue capturing and combusting gas from both legacy and non-legacy waste profiles. The Banksia Road site has operated as a landfill since 1999, with the project proponent, Cleanaway Solid Waste Pty Ltd, taking over operations in 2006. Additionally, the project secured a fixed-delivery carbon abatement contract (CAC163129) with the Australian Government in May 2016, which successfully reached full completion and delivered its required abatement by July 19, 2022.
