A discontinuous lignocellulose fiber is described for use as a reinforcing filler for thermoplastic composite compositions. The fiber filler includes a significant percentage by weight of long, "hair-like" fibers. Specifically, at least about 20 percent by weight of the fiber filler is discontinuous lignocellulose fiber with a fiber length greater than about 15 millimeters and a fiber diameter

lignocellulose composition of oil palm trees. The dry matter of the plant is composed of lignocellulose, which is referred to as lignocellulosic biomass. It is the most abundantly available raw material in the world and has potential for application in biofuel production.

However, the presence of lignin in cell walls limits its efficient utilisation such as in its bioconversion to biofuel. Reduction of the lignin content or alteration of its structure in crop plants have been pursued, either by regulating genes encoding enzymes in the lignin biosynthetic Lignocellulose is made up of cellulose, hemicellulose, and lignin. Cellulose is a polymer of glucose, while hemicellulose is made up of pentose sugars, such as xylose and arabinose, and a smaller percentage of hexose sugars, including glucose, galactose, and mannose [35–39 ]. Lignin constitutes the noncarbohydrate part of the lignocellulose. Lignocellulose refers to plant dry matter , so called lignocellulosic biomass. It is the most abundantly available raw material on the Earth for the production of biofuels, mainly bio-ethanol.

Lignocellulose composition; consequences for plants, fungi and downstream products Climate change, energy transitions and sustainable production of sufficient food and non-food are leading global challenges. Lignocellulosic biomass is mainly composed of cellulose (9%–80%), hemicellulose (10%–50%), and lignin (5%–35%), and its biodegradability is highly affected by its composition. ABSTRACT: The determination of the composition of lignocellulosic substrate is a crucial step in order to determine the overall efficiency of the processes designed to convert lignocelluloses to ethanol. Standard methods as gravimetric, chromatography, and spectroscopic are routinely explored in the scientific literature. Cellulose, hemicellulose, and lignin comprise the main composition of cell walls of plants and are important components of natural lignocellulosic materials. Cellulose molecules determine the cell From a biofuels perspective, cell walls can be considered to be composed of five main components: cellulose, hemicellulose, pectin, lignin, and minerals that are collectively referred to as lignocellulose (table 1).

Rigoberto Gaitán-HernándezI,   for other lignocellulosics even though they may differ in chemical composition and matrix morphology.

Lignocellulose biomass, due to its abundance, is considered as one of the most potential and sustainable sources for the production of value added chemicals 

It is the most abundantly available raw material in the world and has potential for application in biofuel production. By approaching lignocellulose as a multi-level resource, biotechnology could have a significant effect on ecological agriculture, bio-energy, the chemical and paper making industries, etc., ultimately establishing distinctive eco-industrial parks for lignocellulose.
