Birkdale Landfill Gas Project

The Birkdale Landfill Gas Project is a methane capture and electricity generation initiative located at the Birkdale Waste Transfer Station, approximately 20 kilometres southeast of Brisbane's CBD in Queensland. Situated within the Redland City Council local government area, the project operates on a site that served as the region's primary landfill from 1993 until its closure in 2011. The surrounding area is characterised by suburban residential developments intermixed with conservation bushland, specifically the Judy Holt Recreation Reserve which borders the facility.

Registered in November 2012, the project is managed by LMS Energy Pty Ltd. It operates under the Carbon Credits (Carbon Farming Initiative, Electricity Generation from Landfill Gas) Methodology Determination 2021. This methodology rewards the capture and combustion of methane, a potent greenhouse gas released by decomposing organic waste in landfills. By diverting this gas into a combustion engine to generate renewable electricity, the project prevents methane from entering the atmosphere while simultaneously displacing fossil-fuel-based power from the grid.

The Redlands region is known for its distinct red krasnozem soils (deep, structured red clays) and enjoys a subtropical climate with high rainfall, averaging over 1,300mm annually, which is predominantly summer-dominant. These warm, moist conditions historically accelerated waste decomposition, thereby facilitating consistent gas generation.

Interesting aspects of this project include its adaptive lifecycle management. While the landfill itself ceased accepting waste over a decade ago, the gas project has continued to harvest "legacy waste" emissions. In 2022, it was reported that the facility had abated over 779,000 tonnes of carbon dioxide equivalent since its commissioning in 2010. Notably, the project has transitioned through multiple methodology variations to align with updated standards and successfully completed its Carbon Abatement Contract (CAC362004) with the Australian Government in April 2022.
