1. A process, comprising:
providing a mixed C5/C6 monomer sugar stream derived from a plant biomass;
isolating a first target product that is a target monomer sugar or target blend of monomer sugars from the mixed C5/C6 monomer sugar stream to leave a residual mixed C5/C6 monomer sugar stream;
hydrogenating continuously the residual mixed C5/C6 monomer sugar stream to form a mixed C5/C6 alditol stream;
optionally isolating a target alditol or target blend of alditols from the mixed C5/C6 alditol stream to leave a residual mixed C5/C6 alditol stream, wherein the isolating the target alditol or target blend of alditols comprises crystallization, chromatography, or crystallization and chromatography;
continuous hydrogenolysis of the mixed C5/C6 alditol stream or the residual mixed C5/C6 alditol stream to form a mixed C2-C4 polyol stream; and
isolating a second target product that is a target glycol, target blend of glycols, or glycerol from the mixed C2-C4 polyol stream;
wherein at least 10% of the overall target product yield is either the first target product or the second target product.
