Abstract
Biogas is a renewable energy source which is produced by the anaerobic decomposition of the organic and solid waste. It mainly consists of methane, carbon dioxide and a small amount of hydrogen sulphide and moisture. It is a green energy which has a potential of replacing the conventional fuel to some extent. A number of factors are there which affect the production of the biogas production from anaerobic digestion. Factors affecting biogas yields are divided into two main categories, primary and secondary factors. Primary factors mainly comprise of temperature, pH of the slurry, C/N ratio of the composition, organic loading rate, moisture content, Hydraulic Retention Time (HRT) etc whereas secondary factors are design & construction of digester and operation & management. This review is based on the study of the factors affecting the biogas production and their optimization.
