Stapylton Landfill Gas Project

Stapylton Landfill Gas Project is a landfill gas and electricity generation project located at Stapylton, approximately 40 kilometres southeast of Brisbane in Queensland [1]. Registered in July 2014, the project operates within a highly industrial and commercial area heavily utilized for waste management and resource recovery [1, 7]. The surrounding South East Queensland environment experiences a humid, subtropical climate characterized by high annual rainfall, and the local landscape predominantly features alluvial clays and coastal lowland soils due to its proximity to regional river systems.

Landfill gas projects operate by capturing biogas generated by the decomposition of organic rubbish within a landfill [2]. Under the Electricity Generation from Landfill Gas methodology, this captured gas, which is rich in methane, a greenhouse gas significantly more potent than carbon dioxide, is safely combusted and converted into renewable electricity [2, 8]. This process provides a dual benefit: it prevents harmful fugitive emissions from entering the atmosphere and displaces the need for fossil fuel-derived grid electricity.

Operated by LMS Energy Pty Ltd, one of Australia's largest methane abatement and bioenergy companies, the project captures and combusts gas from both legacy and non-legacy waste [4, 5]. Over its operational life, the project has progressively upgraded its crediting framework, transitioning from the 2012 and 2015 legacy methods to the updated 2021 methodology [4]. A government Carbon Abatement Contract (CAC873169) linked to this project, along with the nearby Molendinar and Reedy Creek landfill sites, was successfully completed in June 2022 [4]. The facility continues to be a high-yielding abatement site, regularly generating tens of thousands of Australian Carbon Credit Units (ACCUs) annually, some of which have been utilized by major corporations to offset their scope emissions [3].
