Capture and Combustion of Landfill Gas at Dunmore Recycling and Waste Disposal Depot, Shellharbour City Council

Capture and Combustion of Landfill Gas at Dunmore Recycling and Waste Disposal Depot is a landfill gas electricity generation project located in Dunmore, approximately 20km south of Wollongong in NSW. It was registered in January 2014 and operates over the active footprint of the regional waste facility.

Electricity generation from landfill gas projects involve installing new or continuing the operation of gas collection systems to capture methane-rich biogas from decomposing legacy and non-legacy waste. The gas is then combusted in a flare or engines to generate renewable electricity, which destroys potent greenhouse gases. This methodology requires the carbon abatement to exceed standard regulatory thresholds (such as a 30% baseline) to earn credits.

The surrounding Illawarra region is known for coastal urban development, historical dairy farming, and grazing operations. The area is considered high rainfall, and soils are generally coastal alluvial, sandy loam, and clay.

The project is managed by LGI Limited in a long-term partnership with the Shellharbour City Council. Initially established with a bespoke LGI 1000 ERF-compliant biogas flare, the project transitioned through multiple methodology variations, eventually updating to the electricity generation method in February 2022. The project held a carbon abatement contract (CAC742375) from May 2016 until its successful completion in June 2023. According to recent registry data, it has been issued over 168,000 Australian Carbon Credit Units (ACCUs), providing financial benefits to the council while significantly improving local air quality.
