A widespread use of renewable energy sources is necessary to meet ever rising energy demands of the modern world. Biogas has emerged as a promising renewable energy source, especially in rural India, because of the abundant availability of biomass. Dissemination of biogas technology in India faces several barriers and there is a scope for increased applications of biogas in India. Improvement in methane content of biogas by removal of contaminants can enable widespread applications of biogas. A review of techniques for enhanced biogas production using different pretreatments, and the techniques for biogas quality improvement has been presented. The review may be useful for researchers in the field of biogas energy for further propagation of biogas technology in India.
