Abstract
A process for dewatering biomass material comprising polysaccharide and water. The process comprises wetting the biomass material with a wetting composition comprising an alcohol to form a biomass slurry comprising wetted biomass material and a liquid component, mechanically separating a portion of the liquid component from the biomass slurry, and mechanically separating at least a portion of the water from the wetted biomass material. A process for extracting polysaccharide from the biomass material and a dewatered biomass material are also disclosed.
