NOVELTY - Producing sugar from woody feedstock, involves: providing a woody feedstock comprising cellulose, hemicellulose, and/or lignocellulose; processing the cellulose, hemicellulose, and/or lignocellulose of the woody feedstock at at least one portable feedstock processing unit, each of which is located at or near a woody feedstock provider, to produce sugar in a solution, where the processing comprises mechanical destruction, chemical hydrolysis, and/or enzymatic hydrolysis; and transporting the sugar to a plant for processing the sugar into biofuels or chemicals.    USE - For producing sugar from woody feedstock which is used processing biofuels or chemicals including ethanol, where the sugar is 5C sugars and/or 6C sugars (claimed).    ADVANTAGE - The method and system reduces the transportation costs associated with the production of ethanol from feedstock; reduces the tonnage of feedstock transported from a feedstock provider to an ethanol producer; produces byproducts that may be left at the site of the feedstock provider to be used as animal feed, animal bedding, compost, biofuel, chemicals or the like; produces a non-hazardous material to be transported from the feedstock provider to the ethanol producer; reduces the storage requirements at the ethanol producing plant; reduces or eliminates the environmental impact caused by the storage of feedstock, the disposal of byproducts, waste products and waste water, and the transportation of feedstock to an ethanol producing plant; utilizes largely untapped resources as feedstock; allows feedstock providers to utilize the byproducts of the feedstock processing and derive revenue from feedstock sources that have traditionally been treated as waste; and reduces the size and cost of an ethanol producing plant and improve the efficiency of such a plant. The feedstock used in method is more abundant, less costly to produce and contains greater potential energy than feedstock that is more commonly utilized in the production of ethanol.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a system (S1) for producing sugars, comprising a woody feedstock provider, where the woody feedstock provider is adapted to provide woody feedstock; a woody feedstock comprising cellulose, hemicellulose, and/or lignocellulose; a portable feedstock processing unit that processes the cellulose, hemicellulose, and/or lignocellulose of the woody feedstock to produce sugar in a solution, where processing comprises mechanical destruction, chemical hydrolysis, and/or enzymatic hydrolysis; and an unit for transporting the sugar to a plant for processing the sugar into biofuels or chemicals; and    (2) a system (S2) for producing ethanol, comprising a feedstock provider, where the feedstock provider is adapted to provide feedstock; feedstock; a feedstock processing plant, where the feedstock processing plant is adapted to produce sugar water and wet animal feed from the feedstock; an unit for transporting the sugar water; and an ethanol producing plant, where the ethanol producing plant is adapted to produce ethanol from the sugar water.
