Abstracts: The development of commercially viable “green products” based on natural resources for both matrices and reinforcements for a wide range of applications is on the rise. This effort includes new pathways to produce natural polymers with better mechanical properties and thermal stability and use of natural polymers to make biodegradable plastics and their composites with lignocellulosic fibers. For each category extrusion was carried out at a temperature of 190°C and screw speed of 50 to 70rpm, for fibre content of 10 wt% to 30wt%. The compounded samples were then prepared into test specimens through injection molding process and characterized by tensile testing, Heat deflection temperature (HDT) , Melt Flow Index (MFI). Based on the tests, the fibre content that gives the maximum strength is identified.
