Abstract. A challenge faced by the Red Meat Processing (RMP) industry in Australia is the quantity of by-products generated at the end of the production chain, which require careful treatment before they can be reutilized or released to the environment. The net result is the additional, and significant, costs to the production chain. However, opportunities for reutilization of such by-products have been identified, including: energy, water extraction, and nutrients. The conversion of bioresources, largely regarded as waste, into value-added by-products is potentially a significant source of income to the industry. This paper identifies and analyses by-products from an Australian RMP facility, and reviews closed-loop concepts for bioresource recovery in order to enhance the energy output and produce value-added by-products from the production chain. For this, a detailed analysis of the different technologies currently available in the market for product extraction was carried out. Recovery or reduction strategies for the production of value-add products and technology applications are proffered, which are applicable to the Australian RMP industry.
