Claim:
1. Process of producing improved wood fiber for product uses from green non-food plant biomass, the process comprising: a) hot-water extraction carried out by contacting a charge of the green non-food plant biomass material with liquid water in the absence of any added reagents, in a pressurized vessel at an elevated temperature up to about 250° C., in which the hot-water extraction is adapted so as to yield an aqueous extract containing hemicellulosic components and an improved post-treatment lignocellulosic solid residue as residue material in which the hemicellulosic components thereof are substantially removed therefrom, but in which the cellulose and lignin components are substantially unchanged such that the post-treatment residue material retains its pre-treatment shape, size, and structural integrity; b) separating the aqueous extract from the lignocellulosic residue; c) further processing the separated aqueous extract; and d) processing the improved lignocellulosic residue while leaving the cellulose and lignin contents thereof substantially unchanged but in which a significant portion of the hemicellulosic components are absent to yield useful products with significantly reduced moisture reactivity.
