Abstract

With climate change looming and the unsustainable supply of fossil fuels, the development of renewable and clean energy is urgently required. An often neglected source of clean energy is the organic material contained in waste and wastewater. Millions of tons of solid organic waste and wastewater are generated everyday worldwide. Instead of consuming energy, anaerobic digestion can be applied to treat the generated waste, thus achieving the objective of waste treatment for public health protection and also recovery of renewable methane for heat and power purposes. In this chapter, the benefits of anaerobic digestion will be introduced followed by a discussion on the mechanism and the typical design principles of anaerobic digestion systems. Some of the recent advancement of anaerobic digestion systems such as membrane bioreactors, fluidized bed reactors and co-digestion systems will be presented in the subsequent sections. The state-of-the-art molecular biological tools to monitor and diagnose the microbiology of anaerobic digestion systems will also be discussed. Lastly, the future outlook of anaerobic digestions will be addressed.
