In the present days, the environmental issues such as the greenhouse effect and correct waste disposal methods are gaining much attention throughout the community. In this context, the concept of controlled anaerobic digestion is perhaps a much overlooked example of a way to reduce greenhouse gas emissions and provide a better waste disposal method for organic waste. Biogas technology can not only provide fuel, but is also important for the comprehensive of biomass resources and enhancing the development of agriculture, forestry, animal husbandry, fishery, evoluting the agriculture economy, protecting the ecologic environment, realizing agricultural recycling, as well as improving the  sanitary conditions, in rural areas. Rural India has a vast potential of biogas generation and application. During the past decades, biogas has been promoted mostly as a cooking fuel in the rural areas. Being a renewable source, biogas, when utilized properly, can replace the commercial and nonrenewable energy sources to a considerable extent in a variety of production activities. The aim of this paper is to discuss the various designs of a biogas plant to produce energy with special application to the India. The paper describes the general design considerations of biogas plants.
