1. A method of creating a number of separate product streams from an agricultural waste material, comprising:
- providing a starting material consisting of an agricultural waste material;
hydrolyzing said starting material with an acid solution at atmospheric pressure, and temperatures not exceeding about 100°
C., to create an absorbent, hydrolyzed solid residue and a xylose-containing liquor;
reserving said xylose-containing liquor; and
delignifying said hydrolyzed solid residue with a basic solution with urea, to create a highly absorbent fiber residue suitable for use as an absorbent material, and a dissolved lignin-containing solution.
