Biogas is obtained from biomethanation of biomass waste. The present work aims at a detailed discussion of the different factors affecting the perforation of biomethanation process. Some case studies have been presented to show the techno-economical feasibility of different plants, based on different locally available biomass. In most of the cases plants are installed against adequate financial support with subsidy, but the performance of the plants is being affected due to lack of technical knowhow. Effects of different process parameters such as PH-value, temperature, C/N ratio on biogas generation, needs to be taken care of to ensure maximum generation rate with highest yield. Since biomass is locally available, harnessing energy from it may be a probable solution to end the energy crisis in rural areas which are remote from the power grid, thereby providing immense potential for electrification, application to a large number of industries and last but not the least domestic purpose using Biogas.
