This study focuses on the use of Alibizia Lebbeck Benth pod particles (ALBp) as reinforcement on low density polyethylene (LDPE). Composites were processed via casting where 408 and150 µm ALBp where used in reinforcing LDPE. Samples were subjected to Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), Differential Scanning Calorimetry (DSC). Thermogravimetry Analysis (TGA) impact strength and tensile characterizations. Composites showed improved thermal stability and crystallinity compared to unreinforced LDPE. Tensile strength (UTS) of composite increased by 331% as it improved from 0.36MPa for unreinforced LDPE to 1.55MPa using ALBp of 150µm. Additional C=C and C-O-C groups observed on the composite’s spectrum could be responsible for the improvement in mechanical properties. Reinforcing LDPE with larger ALBp (408µm) culminated in the formation of gaps and voids in the composite
