Wood and non-woody fibers are abundant with different uses according to their composition and physical properties. Unfortunately, a huge amount of non-woody fibers was produced annually with negative environmental effects according to accumulations. Otherwise, the cellulose fibers were used as wood precursor material. Cellulosic materials are considered the most abundant natural, renewable and inexpensive polymer on the earth, considered the backbone of all woody and nonwoody fibers. Generally, the farmer tends to burn the agriculture wastes in the open air, and under uncontrolled conditions, that cause pollution to surrounding environments. These wastes are a rich source of cellulosic materials that shows great potential to be preferable used further with petroleum-based polymers. This review concerns with recycling various agricultural wastes such as rice straw, tree pruning, and cane bagasse... etc, by preparing cellulosic materials that can be used in different applications. Where composites based on recycled polymer and/or agricultural wastes were prepared to be used in various applications. The polymer wood composites are improving the single characterization of materials used and made the WPC biodegradable.
