Unitywater is developing a waste-to-energy feasibility study that could revolutionise the way we think about sewage with support from the Australian Renewable Energy Agency (ARENA).
ARENA has provided $296,000 funding for us to assess the commercial viability of converting the Kawana Sewage Treatment Plant on the Sunshine Coast to produce biogas and electricity from various waste sources. We are also contributing funding to the study.
This project demonstrates the potential to tap into a variety of localised waste sources to produce sustainable renewable energy.
If commercially viable, the project offers an alternative opportunity for power generation for sewage treatment plants of similar scale.
The project will also uniquely demonstrate the use of grease trap waste, a highly concentrated organic waste stream, as an addition to biosolids for waste to energy. The innovative use of grease trap waste as a feedstock will also divert this waste from landfill, reducing the carbon footprint of both landfill gases as well as the energy needs of the facility.
