NOVELTY - Method for saccharifying a cellulosic or lignocellulosic feedstock, comprises: providing a cellulosic or lignocellulosic feedstock; mixing the feedstock with a fluid and a saccharifying agent; and transporting the resulting mixture.    USE - The method is useful for saccharifying a cellulosic or lignocellulosic feedstock (claimed), which is useful to manufacture an intermediate or a product e.g. energy (for electrical power generation, e.g. in a conventional steam generating plant or in a fuel cell plant), a fuel (ethanol) for powering cars, trucks, tractors, ships, trains and aircraft, which is planes (e.g. having jet engines), and helicopters, a food and a material, preferably hydrogen, alcohols (e.g. monohydric alcohols or dihydric alcohols, preferably n-propanol or n-butanol), sugars, biodiesel, organic acids (e.g. acetic acid and/or lactic acid), hydrocarbons and/or co-products (e.g. proteins, which are cellulolytic proteins (enzymes) or single cell proteins). The sugar concentrate is useful in bioprocessing facilities, which manufactures enzymes.    ADVANTAGE - The method: converts a cellulosic or lignocellulosic feedstock to a convenient and concentrated form which can be easily transported and utilized, e.g. in an existing manufacturing facility, for e.g. a plant adapted to manufacture ethanol from starches, e.g. grains or corn, from sucrose-containing materials, or from lactose-containing materials (whey), and easily stored and handled; and provides sugar concentrates, which utilizes less water, thus resulting in substantial manufacturing and transportation cost savings.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) a composition, which is a sugar concentrate, comprising: glucose (10-70 (preferably 15-65 or 20-60) wt.%), xylose (2-35 (preferably 2.5-30 or 5-28) wt.%); and a fluid, which is a solvent, where the total sugar content of the composition is 10-90 (preferably 15-85 or 20-75) wt.%;    (2) a sugar concentrate made by saccharifying a dispersion, which includes 10-90 wt.% of a cellulosic or lignocellulosic material; and    (3) a method for saccharifying a cellulosic or lignocellulosic feedstock, comprising: providing a cellulose-containing cellulosic or lignocellulosic feedstock; mixing the feedstock with a fluid, which is a solvent (preferably water), and a saccharifying agent to saccharify the cellulose; and transporting the resulting mixture, by rail or truck, to a starch-based or sucrose-based ethanol plant to produce ethanol.
