The population growth, along with lifestyle changes, has resulted in unprecedented levels of food waste at all phases of the supply chain, including harvest, packing, transportation, and consumption. Conventional practices involve dumping of food waste with municipal garbage. However, these methods have serious environmental and health consequences. Food waste has a great recycling perspective due to its high biodegradability and water content, making it an ideal substrate for the production of biofuels and other industrially important chemicals including pigments, enzymes, organic acids, and essential oils. This review extensively covers conversion of food waste to generate bioenergy which will help to reduce environmental pollution and facilitate implementation of a circular bioeconomy. Moreover, review also highlights novel technologies like supercritical fluid extraction, ultra-sonication, pressurized liquid extraction, and microwave assisted extractions that are being employed in food waste management to increase the efficiency of value-added product recovery in an economically viable manner. Metabolic engineering of microorganisms for specificity of product would be a future breakthrough in food waste valorization/management.
