The Griffith Biohub is a $58 million circular economy project that implements proven anaerobic digestion technology to convert the under-utilised resource of agricultural organic waste and residues across the Riverina to biomethane (a low-emission renewable gas).
This gas can be delivered via existing infrastructure to increase domestic gas supply and accelerate the decarbonisation of hard-to-abate sectors in NSW, such as industrial heat, chemical feedstocks, and responsive power generation.
Griffith Biohub will process up to 50,000 tons of organic waste in its first phase to produce approximately 330TJ/yr (equivalent to the gas consumed by over 20,000 households), as well as recovering and returning the residual nutrients back to agriculture. The project is due to commence construction in late 2027 and commercial operations in 2029.
The second stage will look to process over 250,000 tonnes of organic waste and residues from across the Riverina.
ORG is also evaluating the utilisation of the biogenic carbon dioxide for industrial use.
ORG acknowledges the collaboration of key project stakeholders, including Jemena Gas Networks and Osaka Gas Australia (OGA), who have actively supported this initiative.
