Conversion of major components (cellulose, hemicellulose, and lignin) of lignocellulosic biomass into usable platform is essential in the integrated biorefinery concept, which simplifies the subsequent production of fuels, chemicals, and materials [1, 2].

To save substantial amounts of crude oil and reduce carbon footprint demands, the upgrade and use ofmaterials from traditionally industrial sectors of wood (wood powder and fibers), textile, and pulp and paper (lignin, hemicellulose, and cellulose fiber industries as well as new biopolymers).
removal of pectin, hemicellulose, and lignin, and to visualize the separation of fibers from fiber bundles. Figure 1 shows the change in morphology of flax fibers after chemical
formaldehyde resin can be produced. Cell wall of lignocellulosic biomass comprises of cellulose, hemicellulose, lignin, small quantity of pectin and extractives. In the current work, cellulose and lignin were extracted from lignocellulosic biomass sources such as flax fiber, alfalfa fiber and wheat straw.
Cellulose can be assayed using a method described by Updegraff in 1969, where the fiber is dissolved in acetic and nitric acid to remove lignin, hemicellulose, and xylosans. The resulting cellulose is allowed to react with anthrone in sulfuric acid .
In particular, lignin, which is the most abundant component of lignocellulosic biomass (along with hemicellulose and cellulose), shows enormous potential for carbon fibre production due to its chemical structure.
hemicellulose, lignin, pectin and extraneous materials. Each cell of fiber comprises of crystalline cellulose regions (microfibrils) which are interconnected via hemicellulose and lignin fragments.
The paper is focused on the analysis of the behaviour of biocomposites (biodegradable composites) which are reinforced with diﬀerent ﬁllers fractions, with varying lignin contents. These materials have been carried-out by extrusion and injection moulding.

Wood is mainly formed by cellulose and hemicellulose, lignin and extractives (Koljonen et al., 2003). Despite different defibration and treatment techniques, the chemical percentage of carbohydrates and lignin of the whole pulps were approximately equal ( Koljonen et al., 2003 ).
The major constituents of natural fibers (lignocelluloses) are cellulose, hemicellulose, lignin, pectin and ash. The percentage of each component varies for each different type of fiber, however, generally, are around 60-80% cellulose, 520% lignin, and 20% of moisture, besides hemicellulose and a small percent of residual chemical components.
