Biogas Technology: An Approach Towards Healthy Environment

Energy plays very significant role in our day to day activities. Today's energy sources are mainly fossil fuels based which are not only limited but also creates Global Warming. Effect of environment, economic, social and technical factor have led the rapid deployment of various sources of Renewable Energy. India had power installed capacity of about 245GW out of which renewable contributes 12%. Of the current total renewable energy base, biomass constitutes about 11.5%. Biomass refers to biodegradable material originating in land and aquatic environments including algae, trees and crops or from animal manure.Traditionally, biomass had been utilized through direct combustion. Cow dung cake is one of the most important and widely used biomass for the production of daily energy needs. It has been estimated that 2.5 billion people around the world are not being able to access the modern fuels[1]. They are highly dependable on locally available wood and cow dung cakes. Burning of biomass or cowdung cakes through direct combustion creates indoor air pollution and ultimately contributing to serious health problems, particularly cancer and respiratory infections.
