Staggering 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, citrus, apple, potato, and tomato), 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.
澳大利亚产生的食物垃圾数量惊人，本综述介绍了基于食物垃圾的生物精炼在澳大利亚迈向循环经济过程中的机遇。文中呈现了澳大利亚当前的食物垃圾情况，包括主要食物垃圾来源、政府监管及当前管理措施的概述。主要的食物垃圾流包括水果和蔬菜（酿酒葡萄、柑橘、苹果、土豆和西红柿产生的垃圾）、坚果（杏仁加工废弃物）、海鲜（鱼类废弃物）、乳清、甘蔗渣以及家庭和企业产生的垃圾。这些垃圾流的成分表明它们有潜力在生物精炼厂中通过直接提取、生物和热化学转化相结合的各种途径用于生产增值产品。最后，阐述了澳大利亚在将食物垃圾作为一种资源加以利用方面所做的努力，以及推动切实可行的商业性食物垃圾生物精炼技术发展所面临的挑战和未来方向。
