Gosnells Landfill Gas Abatement Facility

Gosnells Landfill Gas Abatement Facility is a landfill gas abatement project located at the former City of Gosnells landfill site on Kelvin Road in Orange Grove, approximately 21 kilometres southeast of the Perth CBD in Western Australia. It was registered in August 2013 and covers an unknown area, confined to the boundaries of the former municipal waste facility.

Landfill gas abatement projects involve installing gas collection systems to capture and combust methane, a potent greenhouse gas generated by the decomposition of organic waste. Standard requirements for this methodology dictate that the captured gas must be flared or run through an engine to convert the methane into carbon dioxide, with the volume of gas sent to the combustion device precisely measured and monitored to calculate the resulting carbon abatement.

The semi-rural Orange Grove region sits at the foothills of the Darling Scarp and is characterised by acreage properties, horse paddocks, light industrial sites, and waste management facilities. The area experiences a Mediterranean climate with moderate, winter-dominant rainfall. Soils across this transitional foothills zone generally consist of sandy and gravelly loams that grade into brown clays towards the scarp.

This project originally transitioned from an early, revoked Carbon Farming Initiative (CFI) method to the updated 2015 methodology, allowing it to continue capturing gas from both legacy and non-legacy waste. Over its lifetime, the participant structure has evolved, moving from AGL Energy Services to Sustainable Energy Infrastructure Trust, before transferring to the current proponent, LMS Energy Pty Ltd, in 2022. Furthermore, the project secured a fixed delivery carbon abatement contract with the Commonwealth in April 2015, which was successfully completed in February 2023 after supplying 39,500 carbon credits to the government.
