Renewable energy powers Bondi treatment plant

Posted 28 July 2016

Bondi BeachThe Bondi Wastewater Treatment Plant is now producing enough renewable energy to be 100% self-sufficient.

 The plant has been using co-digestion to convert sewage sludge and organic waste into energy since 2014.

State Minister for Primary Industries, Lands and Water Niall Blair has congratulated Sydney Water on the achievement.

"This project is yet another great example of Sydney Water using research and innovation to turn biogas into renewable energy to power the entire plant, which benefits the environment and reduces operating costs,” Blair said.

"Not only will this project minimise the impact on the electricity grid network, it will also be able to return 13% net energy back to the grid – which is enough to power about 150 households a year."

Member for Vaucluse Gabrielle Upton said the project was of great benefit to the environment and local residents.

"It is great to see the Bondi Plant, which treats the waste of 300,000 people in the area, will now be able to turn a waste product into a valuable resource for our community," Upton said.

"The renewable energy process will also reduce greenhouse gas emissions of around 8000 tonnes a year from Bondi alone, and this is a great outcome for our local environment."

Sydney Water recently announced it would be ramping up biogas production at the Cronulla Wastewater Treatment Plant in a bid to produce 60% of the site's energy needs.

Across the entire network, Sydney Water is generating more than 20% of its total energy needs through renewable energy projects, including eight co-generation sites.

This has reduced greenhouse emissions by more than 70,000 tonnes a year.
