Chapter 10: Advanced Food Waste Valorization Techniques for Bioenergy Production: A Path in the Direction of Environmental Sustainability

The abundant food waste over the world is being extensively generated day by day due to the augmenting demands of the rapid-growing human population. The improper management of the aforesaid threat has indicated the need for an emergency illustrating the development and implementation of specific advanced strategies and perspectives for timely exploitation and valorization. The rising concern regarding environmental issues followed by drastic waning in the amount of fossil resources has forced the research community and the public to use clean and renewable resources for the production of many high-value yields including bioenergy production. Recent advancements in the biotechnological and nanotechnological strategies primarily exemplify their significant contribution to valorization and bioenergy production. Directing towards the circular and green economic perspectives is noted to be an auspicious way for future studies targeting bioenergy production and waste utilization; it would also allow the research community to find out the answers to the questions targeting “how can we fight against the prominent social and environmental impacts instigated by food waste in the environment?”. The specific focus of this study is devoted to finding out the major and recent food waste valorization techniques that can be used for bioenergy production, with special inference on fighting against the environmental impacts instigated by food waste thereby opening a circular bio-economy way.
