SITA Elizabeth Drive Landfill Gas Capture (flaring & electricity generation) - Kemps Creek project

SITA Elizabeth Drive Landfill Gas Capture (flaring & electricity generation) - Kemps Creek project is a landfill gas capture and electricity generation project located in Kemps Creek, approximately 45km west of the Sydney CBD in New South Wales. It was registered in May 2013 and is situated within the 85-hectare Elizabeth Drive Landfill site.

Landfill gas electricity generation projects involve operating a gas collection system to capture methane generated from decomposing organic waste. The standard requirement of this methodology is to ensure the captured methane, which would otherwise be released into the atmosphere as a potent greenhouse gas, is combusted using ground flares or internal combustion engines to generate renewable electricity.

The Kemps Creek and broader Western Sydney region was historically known for grazing and market gardens, but is rapidly transitioning into a major hub for industrial logistics, waste management, and infrastructure, heavily driven by the nearby construction of the Western Sydney International Airport. The area experiences a moderate rainfall climate and features predominantly clay-based podzolic and heavy shale soils.

This project has an extensive history, notable for its multiple methodology transitions. It originally operated under a revoked 2012 legacy waste method before migrating to a 2015 method, and most recently to the 2021 Electricity Generation from Landfill Gas methodology. In 2022, the project's proponent transitioned from Suez Recycling & Recovery Holdings Pty Limited to Cleanaway Solid Waste Pty Ltd following a corporate acquisition. Furthermore, the project successfully fulfilled a fixed delivery carbon abatement contract (CAC600132) with the Commonwealth Government, officially completing the contract in December 2021 after delivering 336,498 tonnes of carbon abatement.
