Anaerobic Digestion of Food Waste for Bioenergy Production

This article starts with the global challenge of the generation and disposal of large amounts of food waste, and how anaerobic digestion (AD) can serve as a promising approach to convert food waste to renewable energy and fertilizers. Then, the fundamental knowledge of AD, including its basic biological processes and important operating parameters is explained, followed by the application of AD for food waste. Finally, AD of food waste is concluded to be a promising technology, but there are still many technical, economic, and social challenges for its wide application.
