Abstract
Engineering of anaerobic digestion is an essential step in the design phase of a biogas plant. In order to achieve maximum efficiency and productivity, there are many considerations to be made. The enhancement of the biogas yield from the cycle of anaerobic digestion by analyzing some of the factors that affect the plant’s efficiency in terms of its versatility as a waste management device, as a source of renewable energy and the role it may play in preserving the environment. These considerations are known for process microbiology and biochemistry, process engineering architecture and properties of feedstock. This chapter intends on covering these aspects and giving some foundation behind specific considerations for biogas plant planning.
