Cedars Road Landfill Gas Extraction and Combustion

Cedars Road Landfill Gas Extraction and Combustion is a landfill gas capture and electricity generation project located at the Cedars Road Waste Facility in South Bingera, approximately 15 kilometres southwest of Bundaberg in Queensland. It was registered in February 2014 and covers an undefined project area constrained to the footprint of the regional landfill. The surrounding Bundaberg area is predominantly utilised for intensive agricultural purposes, including sugarcane cropping, horticulture, and cattle grazing.

Landfill gas projects operating under the Electricity Generation from Landfill Gas methodology involve the installation of infrastructure within a landfill's waste mass to capture methane-rich biogas generated by decomposing legacy and non-legacy organic waste. Once collected, the biogas is sent to a combustion device, such as a flare or an engine, where it can be used to generate renewable electricity. This process physically destroys the methane, a highly potent greenhouse gas, by converting it into carbon dioxide, significantly mitigating the landfill's overall emissions.

The environment of the Bundaberg region is characterised by a subtropical climate with high, summer-dominant rainfall. The regional soils are highly diverse, typically featuring productive basalt-derived red volcanic soils, sandy loams, and heavier clays that actively support the area's robust agricultural industry.

This project transitioned from a revoked Carbon Farming Initiative (CFI) legacy waste method and continues to actively capture and combust gas today. Originally registered to the Bundaberg Regional Council, who were issued 4,047 Australian Carbon Credit Units (ACCUs) in the 2014/15 financial year, project participation was officially varied and transferred to LGI Limited in early 2015. LGI subsequently installed a bespoke, ERF-compliant biogas management system that operates at minimal cost to the council. A carbon abatement contract tied to the project was successfully completed in September 2021, marking a major milestone in a decade-long sustainability partnership between LGI and the council that has drastically reduced local carbon emissions.
