Abstract
Global warming has become the greatest challenge for the world today. Now, researchers are trying to find out an alternative energy source of traditional fossil fuels to evict green house effect. From recent studies it is observed that, biogas has the potential to become an entrusted energy source for the current world as it can be extracted from solid wastes and the extraction processes are not only ecologically sound but also cost effective and is also an hygienic process to dispose the solid wastes. Basically, biogas is consists of methane (50-60%) and carbon dioxide (20-40%); with a small mixture of hydrogen sulfide and siloxanes as impurities. These impurities can damage the efficiency of biogas. But after successful removal of these impurities, the upgraded biogas can be used in different technologies, which are effective to turn biogas into energy source. But, the matter of fact is that, the lacking of knowledge to select proper substrate, not having sufficient knowledge to apply appropriate pre and post treatments of the raw materials creating obstacles to explore the vast application field of biogas. In this paper, we would like to focus on some familiar technologies by which the utilization of biogas can be extended and help to optimize and control the energy crisis of the world.
