Biomass processing system and processing method

Abstract

A system and a method by which the high yield of a final product produced through a pretreatment and a saccharification and fermentation step can be stably obtained, even if a property of the biomass fed to a pretreatment device or the amount of a contained acid component in the biomass may be variable. The biomass is pretreated by a pretreatment device. At least one of pH, acidity, alkalinity, and ultraviolet absorbance of the pretreated biomass is measured by a measurement unit. The amount of a generated decomposition product or a generated undecomposed substance in the pretreatment is obtained on the basis of a measurement result, and an operation condition of the pretreatment device or a property of the biomass before the pretreatment are controlled on the basis of the calculated result.
