PROBLEM TO BE SOLVED: To provide a method for preparing biomass feedstock originated from waste for utilizing waste, for example, as starting material for manufacturing bioethanol by saccharifying fermentation.;SOLUTION: The method for preparing the biomass feedstock originated from the waste includes: a step of dissociating papers-based waste essentially comprising papers into dilution water; a step of suspending garbages-based waste essentially comprising garbages into dilution water; a step of mixing dissociation liquid of the papers-based waste and suspension liquid of the garbages-based waste to form a liquid mixture; and a step of producing highly concentrated biomass feed stock and water for discharge by dehydrating the obtained liquid mixture. In the step of producing the dissociation liquid of the papers-based waste and the step of producing suspension liquid of the garbages-based waste or the step of mixing both steps, foreign matter removal treatment is preferably performed. The water for discharge is recycled as dilution water for the step of dissociating papers-based waste and/or the step of suspending garbages-based waste.;COPYRIGHT: (C)2012,JPO&INPIT
