The particle sizes analysis on the properties of date palm–wood-flour (DPF) and groundnut shell–flour (GNSF) in recycled low density Polyethylene (r-LDPE) were studied. The study was performed at 150, 212, 250 and 300 µm sizes. The impact energy of Date palm-wood-flour-recycled-low-density-Polyethylene (DPF-r-LDPE) and groundnut shell–flour-recycled-low-density-Polyethylene (GNSF-r-LDPE) composite improved with sizes range, respectively. The other properties of the composite reduced at above 250 µm of fiber injection in the r-LDPE matrix. Scanning electron microscopy (SEM) differentiated the bond between DPF and GNSF in the r-LDPE. Based on the result obtained, DPF indicated good mechanical properties than DPF when reinforced in the r-LDPE plastics.
