Kincumber Landfill Gas Abatement Facility

Kincumber Landfill Gas Abatement Facility is a landfill gas project located at the Kincumber Waste Management Facility on Cullens Road, approximately 15km southeast of Gosford on the New South Wales Central Coast. It was registered in August 2013, and while its exact area size is officially recorded as unknown, it operates directly across the footprint of the landfill facility. The surrounding Central Coast region features a land-use mix of urban residential development, coastal fringes, and native bushland reserves. The Kincumber area experiences a moderate-to-high rainfall coastal climate, with local soils primarily consisting of coastal sands, heavy clays, and sandstone-derived profiles.

Landfill gas projects involve capturing the methane-rich gas that is naturally generated from the decomposition of organic waste in a landfill. Under the Carbon Credits (Carbon Farming Initiative - Landfill Gas) Methodology Determination 2015, standard requirements dictate that this captured methane must be combusted, either via flares or electricity generators, to convert it into carbon dioxide. Because methane is a highly potent greenhouse gas, combusting it significantly reduces the site's overall global warming impact.

This facility has an interesting operational history, transitioning from a revoked 2012 legacy waste methodology to the current 2015 determination in June 2015. The site captures gas to power a 1-megawatt (MW) reciprocating gas engine that generates renewable bioenergy. In November 2023, management of the site shifted when the project proponent changed from AGL Energy Services Pty Ltd to LMS Energy Pty Ltd, one of Australia's leading bioenergy developers. Although the Central Coast Council has since closed the site as a public waste transfer station, LMS Energy continues to actively capture and combust gas from both legacy and non-legacy waste. The project also successfully delivered on a carbon abatement contract (CAC207884) that was completed in June 2022.
