The exploitation of waste from pistachio shell particles (PS) and recycling them to reinforce unsaturated polyester(UPS); it is possible to produce structural sections at an inexpensive price and reduce the risk of environmental pollution resulting from these wastes (PS), instead of the usual incineration and landfill operations with such waste.The samples were prepared by manual casting method according to the weight fractions (0, 5, 10, 15, 20, 25, 30)from the pistachio shell particles (PS) with a fixed granular size of (45 µm) of (PS). Some mechanical tests (the tensile elastic modulus, the bending test, and the hardness test) were carried out. Through testing, these values were increased with the increase in the reinforcement ratios of particles (PS).
