Abstract The latest advancements in technology have led to the progress in designing more efficient anaerobic digestion (AD) systems which have incorporated
modifications such as feedstock pretreatment methods, bioprocess improvements,
techno-economic gas upgrading, and superior digester designs among others. The
different types of feedstocks being used, the mechanism of biogas production, the
operation of a biogas plant, and the different types of digesters used for anaerobic
digestion are explained. The various process parameters like pH, temperature,
electrical conductivity, etc. are also discussed. Challenges in anaerobic digestion
along with the advantages and disadvantages of biogas generation are deliberated.
Further, the microbial population involved in various stages of process is presented.
In this chapter, the existing state of biogas technology highlights the latest advancements in its applications as well as production.
