Reutilización de residuos ópticos en la fabricación de estoperoles viales

Abstract

The thesis project titled "Reuse of Optical Waste in the Manufacturing of Road Studs" evaluates the technical and environmental feasibility of using recycled polycarbonate (PC-R), derived from optical waste such as lenses, to manufacture road studs. These devices are crucial for road signaling, enhancing traffic safety. The study addresses the issue of low recycling rates for polycarbonate, a persistent environmental pollutant, and explores its potential reuse in infrastructure applications. Using a factorial experimental design, parameters such as temperature, pressure, and cooling time in the injection molding process were analyzed to optimize the material's mechanical properties. Results showed that while PC-R met compression resistance requirements, it fell short of flexural strength standards, indicating the need for adjustments in formulation or processing. Compared to materials like polypropylene (PP) and high-density polyethylene (HDPE), PC-R demonstrated environmental and economic advantages but had technical limitations. The project concludes that, with further improvements, PC-R could serve as a sustainable alternative for road studs, aligning with circular economy principles and reducing the environmental impact of plastic waste.
