Report extract

This report provides the final summary and project failure reporting for ARENA project G00866 – A feasibility study to undertake an assessment of the commercial viability of a waste to energy project at Unitywater’s sewage treatment plant.

With Unitywater’s Kawana sewage treatment plant (STP) as an example site, Unitywater identified that the addition of liquid wastes in the form of fats, oils and greases utilised latent capacity in the anaerobic digester on site, increasing biogas production. This increased biogas productions results in a decrease in fossil fuel usage for the plant, and presents a positive energy returned on energy invested (EROEI) ratio.

The feasibility assessment included the design of unloading facilities, receival facilities and equipment for the introduction of additional waste feedstocks into anaerobic digestion.
