Greenpoint Landfill Gas Abatement Facility

Greenpoint Landfill Gas Abatement Facility is a landfill gas project located at the former Green Point landfill on Koolang Road, approximately 6km southeast of Gosford in the Central Coast region of New South Wales. It was registered in August 2013 and operates on a closed and rehabilitated 24ha landfill site. The surrounding land use is now characterised by residential suburbs, woodland remnants, and coastal reserves.

Landfill gas projects involve the installation of gas collection systems, comprising vertical wells and horizontal pipes, to extract methane generated by decomposing organic waste. This captured gas is then combusted (flared) or used to generate electricity, converting the potent methane into carbon dioxide and water to significantly reduce the site's greenhouse gas emissions.

The Central Coast region is classified as a high-rainfall coastal environment, typically receiving over 1,200mm of rain annually. The local geology predominantly consists of Narrabeen Group sandstone, resulting in soil types that generally range from sandy loams to clays, which can influence gas migration and collection efficiency.

This transitioning project was originally established under the earlier Carbon Farming Initiative (CFI) and continues to manage emissions by capturing gas from both legacy and non-legacy waste long after the site's closure to active dumping. Originally managed by AGL Energy Services Pty Ltd, the project proponent formally changed to the site owner, Central Coast Council, in late 2021. Local government records indicate that the ongoing operation, maintenance, and management of the site's flare gas collection system has been contracted to Run Energy Pty Ltd.
