Claim:
1. A method for producing nanocrystalline cellulose from biomass, the method comprising: extracting hemi-cellulose from the biomass to produce a first biomass portion and a first extract; extracting lignin from the first biomass portion to produce a cellulose portion and a second extract; processing the cellulose portion into cellulose nanofibrils, the nanofibrils comprising nanocrystalline cellulose separated by regions of amorphous cellulose, wherein the processing the cellulose portion comprises milling of the cellulose portion into a pulp; hydrolyzing the amorphous cellulose in the nanofibrils to produce a solution of nanocrystalline cellulose and glucose; and separating the nanocrystalline cellulose from the glucose.
