DEFINITION

Classification: 106/137.1

Lignocellulosic material (e.g., flock, sawdust, wood, etc.):

(under subclass 136.1) Compositions wherein the cellulosic material is a lignocellulosic material.

(1) Note. Lignocellulosic material is raw vegetable matter consisting primarily of cellulose, primarily of cellulose and lignin, or primarily of cellulose and lignin and minor amounts of carbohydrate and resin.

(2) Note. Lignin is a noncarbohydrate, polymeric substance found in wood and woody plants which functions as a natural plastic binder for the cellulose fibers. It is isolated directly from wood or wood products or from the treatment of wood, e.g., waste sulfite liquor or black liquor. The structure of the lignin monomer is not completely known.
