The use of synthetic glass fiber as reinforcement is hazardous and its degradation is not easy, although these composites are useful for various applications. Hibiscus sabdariffa (Sorrel) has high (73.9%) cellulose content, tensile strength, and is present in abundance in nature through-out the world, but it is fragile and weather prone, that can be improved by graft copolymerization. Sorrel stem fiber was graft copolymerized with binary vinyl monomeric mixtures that transformed the properties and behavior of the fiber. These physico-chemico-thermally resistant graft co-polymers were then used as reinforcement in phenol-formaldehyde polymer matrix, and subjected to characterization and evaluation by advanced technique. Mechanical potential such as tensile strength, compressive strength, wear resistance, modulus of elasticity, modulus of rupture, stress at the limit of proportionality and hardness were screened to compare the change with the phenoplast. These fibers reinforced bio-composites exhibited physicochemico- thermal resistance and improved mechanical strength for better scientific and industrial applications. The graft copolymerization of waste biomass caused transformation in the properties of the fiber, and made it useful for reinforcement in polymer matrix that improved its bioremediation and biodegradation
