This RIRDC report examines a hatchery survey that was conducted to establish how Australian chicken meat hatcheries handle and dispose hatchery waste; and a literature review on current and potential methods of handling and processing hatchery waste. The research reveals that the majority of hatchery waste is sent to land fill or is directed for composting. Hatchery wastewater is mostly used for irrigation or disposed directly into the sewer. The literature review identified that waste can be separated into both solid and liquid waste by centrifuging or by using screens. Potential methods for treating hatchery waste on site include use of a furnace to heat the waste to produce steam to run a turbine generator or to use an in line composter to stabilise the waste. There is also potential to use an anaerobic digester system to produce methane and to use the resulting biosolids as designer fertilisers.
