NOVELTY - Converting biomass into ethanol comprises: (a) processing a first portion of lignocellulosic biomass to produce ethanol and non-ethanol forming materials, the processing including heating; (b) collecting at least a portion of the non-ethanol forming materials left after the processing; drying the collected non-ethanol forming materials; (c) burning the non-ethanol forming materials to generate heat; and (d) supplying the heat to a processing of a second portion of lignocellulosic biomass to produce ethanol.    USE - The processes are useful for converting biomass into ethanol; isolating energy containing material from process streams of the process of converting biomass into ethanol; and for recovering burnable fuel material, preferably for recovering burnable fuel material from conversion of lignocellulosic biomass to ethanol (all claimed).    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are:    (1) a process for isolating energy containing material from process streams of the process of converting biomass into ethanol comprising isolating solid residues from a process stream produced from the production of ethanol from lignocellulosic biomass; concentrating non-ethanol forming materials in a liquid process stream left after ethanol and solids removal producing a concentrate; and drying the solid residues and concentrate to produce a burnable fuel;    (2) a process for recovering a burnable fuel material from conversion of lignocellulosic biomass to ethanol comprising processing lignocellulosic biomass to produce a product stream comprising ethanol, solids and other organic material; removing the ethanol from the product stream leaving a non-product stream; isolating the solids from the non-product stream; removing water from the non-product stream producing a concentrated non-product stream; and drying the solids and concentrated non-product stream to produce a burnable fuel; and    (3) a process for recovering burnable fuel material comprising obtaining lignocellulosic biomass from plant material grown within about 50 miles of a lignocellulosic biomass processing facility; processing a first amount of the biomass to produce ethanol; collecting by-product materials from the processing of the biomass; processing the by-product materials to form a burnable fuel material; and burning the burnable fuel material on-site at the lignocellulosic biomass processing facility to produce energy.
