The demand of energy is increasing day by day. So we are forced to non-conventional energy sources. The bio energy place a major role to meet the energy demand. There are different sources of renewable energy available.  But the Biogas technology is proved to be the most promising sources of renewable energy.  The Biogas technology has the potential to meet the energy needs in rural/urban area. Biogas technology is found to be cheap, non-polluting, eco-friendly, and self-content. The amount of solid wastes generated in developing countries such as India has steadily increased over the last two decades as a result of population explosion and continuous growth of industries and agricultural practices. Particularly large quantities of fruits waste and flower waste generated, which could be used as biogas inputs to compliment the fuel usage alternative. In addition, a large number of families and educational institute (hostels) generate heavy waste in the kitchen on a daily basis, which could be converted to economic benefits. In this work a comparative study of biogas production from kitchen waste, mixed fruit waste and flower wastes was conducted under the same operating condition. The each waste mixed with water and loaded into the reactor. Biogas production was measured for a period of 20 days and at an average temperature of 33?C. Biogas production started on the 5th day and attained maximum value on the15th days of reactor. The average biogas production from fruit waste, kitchen waste and flower waste was measured. It’s concluded that the waste can be managed through conversion into biogas, which is a source of income generation for the society.
