DEFINITION

Classification: 106/164.01

Lignocellulosic material (e.g., wood, bark, straw, bagasse, wood pulp, etc.):

(under subclass 163.01) Compositions wherein the cellulosic material is raw vegetable matter consisting primarily of cellulose, primarily of lignin and cellulose, or primarily of lignin and cellulose and minor amounts of carbohydrate and resin.

(1) 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.

(2) Note. Lignocellulosic materials include but are not limited to: straw, bagasse, corn stalk, grass, wood pulp, wood, bark.
