'Belrose landfill gas project

Belrose landfill gas project is a landfill gas emissions destruction project located at the closed Belrose landfill site in Northern Sydney, approximately 15-20km north of the Sydney CBD. It was registered in June 2026 and, while the specific area size is unspecified, it operates entirely within the footprint of the old municipal landfill. The Belrose area is predominantly urban and residential, bordered closely by native bushland. The region experiences high coastal rainfall, and the local soils are largely derived from Hawkesbury sandstone, typically presenting as sandy loams and clay.

The project involves upgrading an existing landfill gas collection system to increase the capture and combustion of methane gas generated from both legacy and non-legacy waste. Under the Carbon Credits (Carbon Farming Initiative-Reducing Methane Emissions from Landfill Gas) Methodology Determination 2025, projects capture landfill gas, which is rich in methane, a greenhouse gas roughly 28 times more potent than carbon dioxide, and combust it. In this flaring-only project, the methane is destroyed and converted into carbon dioxide, a significantly less potent gas. Standard methodology requirements mandate the continuous monitoring of gas flow volumes, methane concentration, and flare operational temperatures to ensure high destruction efficiency and accurately calculate the resulting carbon abatement.

An interesting fact about this site is that it successfully generated electricity from its methane gas until 2022. Today, the remnant methane is still captured but flared into the atmosphere to create abatement. Furthermore, the project's proponent, LGI Limited, in partnership with the NSW Government and the Waste Asset Management Corporation, is actively repurposing the site to host a state-of-the-art 12MW/24MWh Battery Energy Storage System (BESS). Revenue generated from leasing the site for this grid-scale battery project will help cover the ongoing costs of methane flaring and fund the rehabilitation of other closed landfills across the state.
