Food waste biorefinery towards circular economy in Australia

Bioresour Technol. 2023 Sep 9:129761. doi: 10.1016/j.biortech.2023.129761. Online ahead of print.ABSTRACTStaggering amounts of food waste are produced in Australia and this review provides food waste based biorefinery opportunities in moving towards a circular economy in Australia. The current food waste scenario in Australia including an overview of primary food waste sources government regulation and current management practices is presented. The major food waste streams include fruit and vegetable (waste from wine grapes apple citrus tomato and potato) nuts (almond processing waste) seafood (Fish waste) dairy whey sugarcane bagasse and household and businesses. The composition of these waste streams indicated their potential for use in biorefineries to produce value-added products via various pathways combining direct extraction and biological and thermochemical conversion. Finally the efforts made in Australia to utilize food waste as a resource as well as the challenges and future directions to promote the development of concrete and commercially viable technologies for food waste biorefinery are described.PMID:37696335 | DOI:10.1016/j.biortech.2023.129761
