Abstract
A process and materials are described in which highly refined celleuloise fibers are broken down into microfibers and further processed into compositions, films. coatings and solid materials which are biodegradable and even edible. The process for the formation of hardenable compositions may comprise:providing a composition comprising non-wood cellulose fiber, 36. mechanically reducing the size of the non-wood cellulose fiber to less than 2 mm, reducing the amount of binding of microfibers by lignin within said non-wood cellulose fibers present in said composition comprising cellulose fiber to form a first fiber product, providing pressure of at least 300 psi to said first fiber product while it is in the presence of a liquid, and removing said pressure within a time interval which will cause said cellulose fiber to break down into a second fiber product comprising microfibers in said liquid.
