ACCC authorises Sydney Water and a group of Sydney councils to procure the development of an organic waste bio-refinery

On 4 February 2026, the ACCC issued a final determination granting authorisation to Sydney Water Corporation, Campbelltown City Council, Wingecarribee Shire Council and Wollondilly Shire Council to engage in certain conduct related to the procurement of the development of an organic waste bio-refinery in south-western Sydney. The bio-refinery will process food and garden organic waste and wastewater organics. Specifically, the authorised conduct is forthe parties to:

• jointly evaluate request for proposal responses for the development of the biorefinery
• collectively negotiate non-exclusive, long-term supply agreements with the chosen developer
• enter and give effect to those agreements.

The ACCC considers that the conduct is likely to result in a public benefit and that this public benefit would outweigh any likely public detriment.

The ACCC has decided to grant authorisation until 31 December 2052.
