Exploiting Environmental Waste) Plastic Medical Syringes) To Prepare Structural Sections

Abstract

In this paper, particles from the waste of plastic medical syringes (WPMS) were recycled with a polymeric resin that hardens with heat from unsaturated polyester (UPS) used to produce an adhesive at a low-cost and multi-use structural sections that have a wide variety of applications in buildings and a number of industries, including (Furniture, toys, etc.). The method of manual casting of the prepared samples was used and the percentage of particles (WPMS) was in such fractions (0%, 30%, 40%, 50%, 60%, 70%, 80%) and in a granular size of (0.45mm). The samples were subjected to mechanical tests to study some mechanical properties (tensile elasticity modulus, bending strength, impact) and at laboratory temperature of (27°C). The results of the mechanical properties (tensile elasticity modulus, bending strength, impact strength) showed ideal values, that are enhanced by increasing the volumetric ratios of WPMS particles, and through the obtained practical results, this type of waste can be used in the construction of the ready-made structural sections at the lowest cost, in addition to reducing the risk of pollution resulting from those wastes instead of burial or incineration, noting that this type of recycling is used for the first time in manufacturing such structural sections.
