Dairy waste streams


Reducing and utilising waste is a priority for dairy processors, as a means of reducing costs and environmental impact. A wide range of potential technologies (Figure 1) may be used to biologically convert wastes into energy and products but the complex and varied nature of dairy wastes makes an assessment of the best strategy for waste utilisation a challenge. This project aims to assess the commercial potential of emerging pathways for reducing the disposal cost of organic dairy waste streams and the potential to generate additional value for our manufacturing partners. This project is financially supported by the ARC Dairy Innovation Hub and Dairy Australia and will work with a range of Australian dairy manufacturers to identify and prioritise methods for waste utilisation that are both practical and cost effective.
