Australia’s first biomethane-to-gas project will see thousands of Sydney homes and businesses using renewable green gas for cooking, heating and hot water.

Jemena has signed an agreement with Sydney Water to generate biomethane at the Malabar Wastewater Treatment Plant, in South Sydney. The zero-carbon emission, high-quality biomethane gas will be injected into Jemena’s New South Wales gas distribution network – the largest in Australia with 1.4 million customers.

The Malabar Wastewater Treatment Plant (WWTP), located near the Malabar Headland National Park, is one of Sydney Water’s multiple Anaerobic Digestion (AD) plants. The bulk of the current AD Biogas output is used for electrical power generation and water heating. The balance of biogas that cannot be used via site processes is combusted through waste gas burners.

    Jemena and Sydney Water have prepared a Review of Environmental Factors (REF) which assesses the potential environmental and social impacts of the project on the site and surrounding environment.

    The REF will be available for public exhibition from 16 September 2021 and welcome comments on the REF or the project.

    Members of the community are invited to review the REF and submit feedback during the exhibition period, from 16 September 2021 and will close on Friday 8 October 2021. Please direct your feedback to the Project Team via the email address: MalabarProject@jemena.com.au

    We look forward to hearing from you and sharing information about the Project. If you are unable to write during this time, please feel free to call us anytime, with your questions on 1800-571-972.
