This edited book focuses on agricultural and food waste biomass valorization in various fields such as energy and environment and the development of several other value-added products. The chapters in this book cover different areas like sources of agricultural and food wastes, recent trends on waste utilization, innovations and sustainability of techniques, and challenges associated with valorization of wastes. In the last few decades, scientists and researchers of different countries predicted that waste material generated due to global problems can be used as a potential feeding material for the manufacturing of different valuable products. Hence, there is a need for more research and development of several other value-added products from waste materials. Proper utilization of these waste materials has been discussed in this book. It also covers the bioactive recovery from food waste, health benefits of extracted bioactive, and utilization of valorized products.  The book also explores future technological challenges and sustainability issues. This title is a great resource for environmental and chemical engineers, food scientists, food researchers and technologists, as well as for students and professionals working in this field.
