Dear Pannirselvam, the biogas plant developed by Bhabha Atomic Research Centre is biphasic. The disadvantage of a biphasic plant is, that the easily digestible material gets converted into carbon dioxide in the aerobic phase. Thus, in order to digest the hard to digest components, one loses the more easily digestible ones. The outcome is that the yield of methane is quite low. The BARC plant is basically a waste disposal system, which gives a bit of methane as bonus. The ARTI biogas system serves primarily as a methane generating system, and therefore we use only the anaerobic phase and only such feedstock that is completely digested under anaerobic conditions. Using waste food as feedstock, ARTI biogas plant yields about 250 to 300 g methane per kg (dry weight) food waste. Yours A.D.Karve
