Abstract

The field of wastewater management and alternative energy are one of the most unexplored fields of environmental biotechnology. The biomethane is considered as renewable natural gas which can be derived from organic waste and sewage treatment. In recent past biomethane is emerging as a promising gaseous fuel utilized in a cogeneration or trigeneration power plant. Biomethane usually produced through anaerobic digestion in oxygen-deficient environment where a series of microorganisms convert the complex waste to biogas via liquefaction through a cascade of enzymes. Biomethane produced in anaerobic digester can be utilized for decentralized power generation, and additionally revenue can be gained in the form of a CO2 credits and/or other greenhouse gas emission credits. In the present book chapter, the technical know-how of anaerobic digestion and biocatalyst associated with digester has been depicted. A thorough understanding of the fundamental principles of anaerobic digestion would help to perceive new aspects of bioenergy conversions. The book chapter highlights the concise of biochemistry for biomethane production as well as important major factors involved in the process toward the realization of a stable biomethane-based economy. Successful application of anaerobic digester was found in pilot-scale potential wastewater treatment along with renewable energy production. The proper configuration anaerobic digester and efficiently pretreated "feedstock" are key to maximize the production of methane. Therefore, basics of reactor design designs based on process economy have been discussed.
