Barretta Landfill Gas Project

Barretta Landfill Gas Project is a landfill gas capture and combustion project located at Barretta, approximately 30km south of Hobart in Tasmania. It was registered by the Kingborough Council in August 2015. While the exact area size is not specified in the public registry, the project operates within the footprint of the Barretta Waste Management Facility.

Landfill gas projects under this methodology involve the installation and continued operation of a gas collection system to capture biogas generated by the decomposition of legacy and non-legacy organic waste. Under standard requirements, this captured methane, a highly potent greenhouse gas, is directed to a flare or engine where it is combusted and converted into carbon dioxide and water, substantially reducing the site's overall emissions.

The Barretta area on the fringe of the Huon Valley is known for its semi-rural landscape, characterized by coastal woodlands, small rural-residential properties, hobby farming, and a history of fruit orchards. The region experiences a cool-temperate maritime climate with moderate rainfall. The local environment features a high diversity of soils, primarily consisting of podzolic soils formed over mudstone and sandstone, alongside pockets of highly productive ferrosols derived from tertiary basalt.

This project has been an active contributor to the Commonwealth's emissions reduction targets. It originally operated under the 2012 legacy waste methodology before varying to the updated Carbon Farming Initiative-Landfill Gas Methodology Determination 2015 in October 2015. In the December 2018 auction, the Kingborough Council secured a fixed delivery Carbon Abatement Contract (CAC354122) for the project. Through this agreement, the facility successfully delivered its committed 24,000 tonnes of abatement to the Commonwealth, officially completing the contract in September 2019.
