Horsley Park Landfill Gas Project

Horsley Park Landfill Gas Project is a landfill gas project located in Horsley Park, approximately 40km west of Sydney in New South Wales. It was registered in December 2012 and operates over an unspecified area, acting as part of a major Veolia waste management facility.

Landfill gas projects involve the active capture of methane produced by the decomposition of organic waste. Once captured, this methane is combusted using a flare or an electricity generation engine. Because methane is a highly potent greenhouse gas, this process converts the emissions into carbon dioxide, which significantly reduces the overall global warming potential of the landfill facility.

The Horsley Park area is situated on the urban fringe of Western Sydney, a region heavily characterized by industrial developments, large-scale waste and resource recovery facilities, logistics networks, and semi-rural agricultural properties. Environmentally, the area experiences a temperate climate with moderate, semi-arid rainfall, and its terrain consists predominantly of Wianamatta shale and heavy clay soils typical across the Cumberland Plain.

This project was originally established under a revoked Carbon Farming Initiative (CFI) method and successfully transitioned to continue capturing and combusting gas generated from both legacy and non-legacy waste streams. It has undergone multiple method variations over its lifespan to remain aligned with the latest methodology determinations. A notable milestone for the project was securing a Fixed Delivery Carbon Abatement Contract (CAC254087) with the Commonwealth in April 2015, which successfully saw the delivery of over 280,000 tonnes of abatement and has now been fully completed. In May 2026, the primary project participant name was officially transitioned from Veolia Environmental Services (Australia) Pty Ltd to VELMS Joint Venture Pty Ltd.
