1. A method for dispersing cellulose based fibers in water comprising the steps of:

  • combining together water, a fibrous material, and a hydrocolloid to form an initial fibrous mixture in which the fibrous material is not initially dispersed in the water and has an initial solids content in a range from about 35% to about 80% by weight of the initial fibrous mixture, wherein sufficient hydrocolloid is included so as to bind substantially all of the water;

    kneading the initial fibrous mixture using strong mechanical action in order to liberate and disperse individual fibers from the fibrous material and form a final fibrous mixture in which the fibers are substantially dispersed throughout the final fibrous mixture; and

    shaping the final fibrous mixture into a desired shape by a process selected from the group consisting of extrusion, injection molding, coating, pressing, rolling, and combinations thereof.
