Amount of biosolids produced annually through sewage treatment in Australia. Biosolids are a byproduct of the treatment of wastewater. Currently most of the output is stockpiled at various sewage treatment plants.

Australian Renewable Energy Agency (ARENA) announces funding for a pioneering project aiming to turn biosolids from sewage into crude oil. Southern Oil Refining will implement the pilot project at its refinery near Gladstone, Queensland in partnership with Melbourne Water and utilize the latter;'s stockpiled biosolids wastewater treatment facility at Werribee.
Estimated cost of the project which involves building a demonstration scale hydrothermal liquefaction reactor to produce the renewable crude oil from biosolids. The liquefaction treats the biosolids using a thermochemical conversion process to produce a biocrude( renewable crude oil). The biocrude will then be upgraded to renewable diesel and potentially renewable jet fuel using Southern Oil Refining’s existing facilities.
Funding that will be provided by ARENA. ARENA has previously funded Southern Oil Refining to build a first-of-its-kind biocrude and biofuel laboratory and testing facility built onsite at Gladstone as part of its advanced biofuel pilot plant.
