Capture and Combustion of Landfill Gas from Benaraby Landfill Project

Capture and Combustion of Landfill Gas from Benaraby Landfill Project is an Electricity Generation from Landfill Gas project located at Benaraby, approximately 20km south of Gladstone in Queensland. It was registered in January 2013 and operates at the Gladstone Regional Council's primary waste facility.

Electricity Generation from Landfill Gas projects involve installing or upgrading gas collection systems to capture methane-rich biogas, produced by decomposing legacy and non-legacy organic waste, and combusting it in a generator. This process prevents potent methane emissions from venting into the atmosphere while actively producing dispatchable renewable electricity for the grid.

The Gladstone and Benaraby region is a subtropical area known for industrial operations, beef cattle grazing on native pastures, and scattered horticulture. The area experiences moderate to high rainfall, typically averaging over 900mm annually. Soils in the surrounding landscape are highly varied, commonly featuring alluvial soils in drainage lines, clays, and materials derived from sedimentary, volcanic, and granitic rocks.

Notably, this was the first new abatement project registered in Australia under the original Carbon Farming Initiative in 2013. Operated by LGI Limited, the facility initially flared the landfill gas before upgrading to a 1MW generator to produce green power. The project successfully transitioned through multiple methodology variations to accommodate the power generation and fulfilled a Commonwealth Carbon Abatement Contract for 662,596 tonnes of abatement, which was officially completed in February 2022.
