Lignocellulosic reinforced thermoplastic composites are relatively new wood materials and are essentially a combination of wood or other lignocellulosics from agricultural plants, and thermoplastic materials along with some additives. Polyethylene (PE), polypropylene (PP), and polyvinylchloride (PVC) are the most used plastics for lignocellulosic reinforced thermoplastic composites. Used beverage carton (UBC) is composed of 70–90% paper, 10-25% low density polyethylene (LDPE), and about 5% aluminum which is existing components of the UBC. Recovering waste material from the UBCs to manufacture a value-added product with an economical and efficient method is an important issue from the perspective of environmental pollution. Rice husks are an important by-product of the rice milling process and are a major waste product of the agricultural industry. It is reported that about 0.23 tons of rice husks are generated per ton of rice produced. The reasons behind the use of rice husks in the thermoplastics are its high availability, low bulk density (90-150 kg/m3), toughness, abrasive in nature, resistance to weathering and unique composition. This study investigated that the physical and mechanical properties of the waste aluminum polyethylene reinforced with rice husk flour. The rice husk content in the composite varied from 40 to 60 wt % in the composites. The LDPE with aluminum particles and rice husk flour were compounded into pellets by twin-screw extrusion, and the test specimens were prepared by injection molding. The composites were manufactured using various weight percentages of LDPE/ricehusk and maleic anhydride-grafted PE. Thickness swelling, water absorption, modulus of rupture, modulus of elasticity, and tensile strength values

were measured. Test results showed that aluminum particles in the LDPE positively affected mechanical properties of the samples as compared to traditional rice husk reinforced polyethylene composites. Based on the findings obtained from the present study, the LDPE with aluminum particles obtained from the UBC could be efficiently used in the manufacture of high performance thermoplastic composite reinforced the lignocellulosics.
