Grantville Landfill Gas Capture and Combustion Project

ERF103347

Project Information:

The Grantville Landfill Gas Capture and Combustion Project is a waste sector initiative located at the Grantville Landfill, situated approximately 3 kilometers southeast of the coastal township of Grantville in Victoria. Registered in April 2016 by the Bass Coast Shire Council, the project operates within the Bass Coast region, an area characterized by a mix of nature conservation reserves, sand extraction quarries, and coastal agricultural land.

The project operates under the Landfill Gas (2015) methodology, which credits the destruction of methane generated by decomposing organic waste. Landfills produce significant amounts of methane, a potent greenhouse gas, which this project collects via a system of vertical wells and pipework. The captured gas is then combusted (flared), converting the methane into carbon dioxide and water, thereby significantly reducing its global warming potential. This specific project claims Carbon Credit Units (ACCUs) for the destruction of gas from both "legacy" waste (deposited before July 2012) and "non-legacy" waste.

Environmentally, the Grantville area benefits from a temperate, high-rainfall climate, receiving approximately 850mm of rain annually. While the broader locality is geologically renowned for its deep sand deposits and active sand quarries ("Grantville Sands"), the landfill site itself utilizes engineered silty clay profiles for capping and containment.

The Bass Coast Shire Council has highlighted this facility as the largest single source of their corporate emissions. In a push for further sustainability, the Council has implemented a 'Hybrid Energy System' at the site, installing wind turbines to power the flare's control systems, replacing the diesel generators previously used to keep the flare operational. Additionally, the Council has noted that the introduction of Food Organics and Garden Organics (FOGO) kerbside collection has successfully diverted thousands of tonnes of organic waste from the landfill, which will eventually stabilize the amount of gas generated by the site in the long term.
