Food Waste to Bioethanol: Opportunities and Challenges

The increasing global population will require sustainable means to sustain life and growth. continuous depletion wastage of the energy resources pose a challenge for survival in coming years. bioconversion waste generated at different stages food value chain ethanol can provide solution depleting way address growing issue globally. high carbohydrate nitrogen content make it an ideal alternative substrate developing decentralized bioprocess. Optimizing process bottleneck issues viz. collection transport, pretreatment, fermentative organism, product separation, which is required economic. current review focuses on opportunities challenges using loss chain, its fermentation produce bioethanol, potential ways improve economics. impact substrate, organisms’ development, downstream processing, by-product stream bioethanol production from commercial success are also discussed.
