    The increased biomass level of bambara groundnut husk (BGH) in the environment through dumping as a refuge due to high consumption rate of bambara groundnut products has been an environmental concerned. The effect of mechanical properties of the recycled polyethylene (RPE) and recycled polyethylene with 20 percent virgin polyethylene (MPE) was investigated. The weight fractions of the BGH filler loading for this experiment were 10, 20, 25, 30 and 35 percent and processed for the reinforcement of RPE and MPE injection moulding machine to examine the mechanical properties on the composites. The tensile strength and modulus, flexural strength and modulus, and hardness of the composites increase fraction of the filler up to 25 percent in the composites and impact strength of the composites decreases with increased filler weight fraction. The increased tensile strength signified that BGH filler may be used for the reinforcement of RPE and MPE. There is significant improvement on the mechanical properties of the MPE composite compared with RPE composite at p < 0.01 and p < 0.05
