Zinfra has been awarded a bronze rating from the Infrastructure Sustainability Council for its work constructing Jemena‘s Malabar Biomethane Injection Plant in New South Wales.
This project is one of a kind in Australia and currently servicing more than 1.5 million homes and businesses across Sydney and its surrounds by injecting upgraded biogas from organic waste back into the gas network.
The rating recognises projects that have been sustainably developed across their planning, design, and construction phases.

Zinfra managing director Peter Iancov says, “The Malabar Biomethane Injection Plant has set the benchmark for building and operating sustainable energy assets in Australia. Not only did we construct the plant, but we also upskilled our teams to operate and maintain this new asset to allow us to effectively support Jemena to fulfil its future energy transition ambitions safely and efficiently.
“This bronze rating from the Infrastructure Sustainability Council demonstrates Zinfra’s ability to deliver projects that are better for the environment while also serving the communities we operate in.”
The Malabar Biomethane Injection Plant was awarded the bronze rating based on four categories: Innovation, Energy, Materials and Knowledge Sharing.
Jemena managing director David Gillespie says the Malabar Biomethane Injection Plant is demonstrating the application of biomethane in Jemena’s NSW gas network—which services more than 1.5 million homes and businesses across Sydney and regional New South Wales.

“While homes and businesses are already receiving small amounts of biomethane which is being injected into the gas network, biomethane has the potential to decarbonise our manufacturing and industrial sector,” Gillespie says.
“We know not every industry can electrify due to the high-heat loads required for their operations or it’s simply too costly. Biomethane is offering an alternative that can help decarbonise our industrial sector.”
The Malabar Biomethane Injection Plant is co-located at Sydney Water’s Wastewater treatment site in Sydney’s south-eastern suburbs and takes the biogas generated by organic waste, upgrading it to biomethane through a process called anaerobic digestion.
