DEFINITION

Classification: 106/162.5

With lignocellulosic material (i.e., mixture of a lignocellulosic material and a carbohydrate material which is other than a lignocellulosic material or a component thereof):

(under subclass 162.1) Compositions which contain a lignocellulosic material in addition to the carbohydrate or derivative whereby the carbohydrate or derivative is not a lignocellulosic material or a constituent thereof.

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

(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.

(3) Note. See this class, subclass 163.01 for definition of cellulose.
