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; hydrolyzing the amorphous cellulose in the nanofibrils to produce a solution of nanocrystalline cellulose and glucose; and separating the nanocrystalline cellulose from the glucose.
