Mirabooka Landfill Gas Project

Mirabooka Landfill Gas Project is a landfill gas capture and combustion project located in Mirrabooka, approximately 14km north of the Perth CBD in Western Australia. It was registered in August 2012, and while its specific spatial area is not listed, it operates within an established solid waste landfill. The surrounding region is predominantly urban, characterised by residential suburbs, commercial zones, and waste management facilities. The local environment features a Mediterranean climate with moderate, winter-dominant rainfall, and the soils across this part of the Swan Coastal Plain are typically sandy.

Landfill gas projects under the Carbon Farming Initiative involve installing a network of gas collection wells and infrastructure to capture methane gas produced by the anaerobic decomposition of organic waste. The standard methodology requires this captured gas to be safely combusted, either through flaring or by powering engines to generate renewable electricity. This combustion process converts the highly potent methane into carbon dioxide, drastically reducing the overall greenhouse gas impact of the landfill.

This project transitioned from an older, revoked Carbon Farming Initiative (CFI) method to the 2015 legislative determination and continues to abate emissions from both legacy and non-legacy waste. It is operated by LMS Energy Pty Ltd, one of Australia's largest and most experienced bioenergy and methane abatement developers. As an interesting milestone, the project was contracted to the Commonwealth in August 2012 under Carbon Abatement Contract CAC362004, which successfully completed its delivery obligations for fixed abatement in April 2022 alongside a portfolio of several other LMS Energy sites.
