Greenpoint Landfill Gas Abatement Facility

Greenpoint Landfill Gas Abatement Facility is a landfill gas project located at the Kincumber Waste Management Facility in Green Point, approximately 10km southeast of Gosford on the New South Wales Central Coast. Registered in August 2013, the project operates on a site that has largely ceased active landfilling, functioning primarily as a waste transfer station while continuing to manage gases from historical waste deposits.

The project operates under the Carbon Credits (Carbon Farming Initiative, Landfill Gas) Methodology Determination 2015. This methodology involves the installation and operation of a system to collect methane-rich gas generated by decomposing organic waste. Instead of allowing this potent greenhouse gas to vent into the atmosphere, it is captured and combusted, often to generate electricity. This specific project captures gas from both legacy waste (deposited before the project commenced) and non-legacy waste.

The Green Point and Kincumber region is characterized by a coastal climate with high annual rainfall, typically exceeding 1,300mm. The local terrain consists of coastal lowlands and slopes with soils generally classified as sandy loams derived from the underlying Narrabeen Group sandstone.

Originally operated by AGL Energy Services, the project proponent changed to the Central Coast Council in December 2021. This shift aligns with the Council's broader initiative to manage its own renewable energy assets; reports from 2018 indicate that gas extraction across the Council's waste facilities was generating enough electricity to power over 4,500 local homes. Although the Kincumber site is closed to new putrescible waste, the "legacy" waste deep underground continues to produce methane that requires active management.
