Food chain-based waste is generated in tonnes globally and this has led to release of greenhouse gases, poor air quality, land and water pollution. Food wastes are generated in tremendous quantity globally from local producer to international consumers and traders. Authors have used systematic literature review to identify the research gaps, thematic areas, methodology, sustainable techniques and future directions of processing food supply chain waste. Research is focused towards utilization of food waste as source for recovery of value-added compounds through sustainable technologies. Food waste can be utilized to synthesis platform chemicals, nutraceuticals, sugars, bio-fuels, bio-gas and bio-char via thermo-chemical conversion, anaerobic digestion and fermentation processes. This paper summarizes and provides technical insights on achieving circular bio-economy via technological advances in food waste processing for enhanced recovery of value-added compounds and future industrial scale operations. The state of art perspectives of food waste valorization and market outlook of platform chemicals and other products provides profitable economy for the food waste generator. Food security requires holistic approaches for effective usage of resources with inter linked global policies.
全球产生了基于食物链的大量废物，这导致了温室气体的排放、空气质量差、土地和水污染。从当地生产者到国际消费者和贸易商，全球都产生了大量的食物垃圾。作者使用系统文献综述来确定研究差距、主题领域、方法、可持续技术和处理食物供应链废物的未来方向。研究集中在利用食物垃圾作为通过可持续技术回收增值化合物的来源。通过热化学转化、厌氧消化和发酵过程，食物垃圾可用于合成平台化学品、营养保健品、糖、生物燃料、沼气和生物炭。本文总结并提供了技术见解，即通过食物垃圾处理方面的技术进步实现循环生物经济，以增强增值化合物的回收和未来的工业规模运营。食物垃圾增值的最新观点和平台化学品及其他产品的市场前景为食物垃圾产生者提供了有利的经济效益。粮食安全需要采取整体方法，有效利用资源，并制定相互关联的全球政策。
