Ensiling Biomass for Biofuels Production and Multiple Phase Apparatus for Hydolyzation of Ensiled Biomass
A method, apparatus and system for the hydrolyzation of ensiled biomass is disclosed. Ensiled biomass is processed in multiple phases, resulting in a liquid precursor hydrozate and a solid precursor hydrozate. The liquid precursor having significant economic value, and being suitable for uses such as, for example, lower cost and improved efficiency ethanol production. A method for lower cost, improved efficiency alcohol production that uses the resulting liquid precursor hydrozate being produced at distributed sources is further disclosed.
