Roghan Road Landfill Gas Project

Roghan Road Landfill Gas Project is a waste sector project located at the now-closed Roghan Road Landfill in Fitzgibbon, approximately 15km north of the Brisbane CBD in Queensland. Registered in November 2012, the project was originally established under the Carbon Farming Initiative (CFI) before transitioning to the Emissions Reduction Fund (ERF). It operates under the 2015 Landfill Gas methodology, managed by the Brisbane City Council.

Landfill gas projects involve the installation of gas collection systems, comprising vertical wells and piping, into waste masses to capture methane generated by decomposing organic matter. This captured gas is then combusted, typically through flaring or electricity generation engines. This process converts methane, a potent greenhouse gas, into carbon dioxide, which has a significantly lower global warming potential. The abatement achieved is measured against a baseline of emissions that would have occurred without the system.

The Fitzgibbon region experiences a subtropical climate characterized by humid, wet summers and mild, dry winters. While the specific soil profile of the project site is engineered landfill cover, the surrounding natural terrain of Brisbane’s northern suburbs typically consists of texture-contrast soils and clays derived from sedimentary rock. As a closed landfill site, the surface area is likely rehabilitated for community or recreational use, consistent with the surrounding urban residential land use.

Interesting notes on the project include its operational partnership with LGI Limited, a specialist in biogas management. In 2018, LGI installed a compliant biogas flare and gas extraction infrastructure at the site to optimize methane destruction. The project has successfully completed its carbon abatement contract (CAC403360) with the Australian Government, delivering its committed volume of carbon credits while continuing to generate ACCUs through ongoing gas capture.
