The production of methane is only the latest of a series of fermentation goals folloqing each other in cascade. A series of goals leads to the expected final fermentation goal: maximum ENERGY EFFICIENCY that is maximum economic yield of methanogenesis.
The first goal for maximum energy efficiency is the MAINTENANCE OD AVAILABLE ENERGY of the ensiled biomass for digester feeding. The ensiled biomass preserves most of the available energy only troough an EARLY LACTIC FERMENTATION, due to the growth of good strains of lactic acid bacteria (LAB). On the contrary, the growth of non-LAB causes bad silage fermentation and poor acidification, with losses of available biomass/bioenergy, that is transformed into heat, carbon dioxide and hydrogen.
BIOSILGAS is the starter from which the ENERGY EFFICIENCY in methane production begins!
