| Abstract | Anaerobic digestion of solid biomass is capable of producing methane-rich biogas and reducing the environmental impact caused by the biowastes. Biogas is the combustible gas produced through a biological process, known as anaerobic digestion which is the process operated at low-high temperature ranging from 30-65°C [1] and without air. The nature of the raw materials and the operational conditions used during anaerobic digestion, determine the chemical composition of the biogas [2]. Biogas consists of 55–80% CH4, 20–45% CO2, 5-10% H2 with trace amount of H2S and other impurities [3]. In these compositions, we can see that the combustible components of biogas are CH4 and H2. Other gases are useless, toxic or harmful and have no energy contribution in biogas. Also, among these two gases only CH4 is present in a significant amount. With its physical and chemical properties close to those of natural gas, albeit with a lower methane content more than 50%, biogas can be used to boil water or for cooking instead of LPG, kerosene, charcoal, fire wood [4] used as fuel for process heating, used for lighting purpose, produce electricity via internal combustion engine or used in replacement of diesel or gasoline to drive equipment. On the other hand, the Kyoto Protocol has explicitly defined methane as one of the six key greenhouse gases where the global warming potential of methane is 25 times higher than |
