Subjecting small size of wood and agroindustries wastes to the sub (100-370 °C) and supercritical (370°C < ) condition of water, intensify the hydrolysis reactions of their primary lignocellulosic materials to the useful target chemicals specially, mono saccharides as biofuel feedstock. A series of sequence centrifugation, micro and nano-filtration and reverse osmosis filtration executed on diluted distilled steam water at the end of each process treatment, to separate the condensed sugars from any other chemicals. Resulted refine sugar solutions were analyzed for oligo and monosaccharides by chromatography. The maximum production yield achieves during the combined supercritical and then subcritical water treatment.
