Abstract: The main purpose of the project is to utilize the waste Glass fiber reinforced plastic (GFRP) and High Density Polyethylene (HDPE) for different applications under mechanical recycling process. Fiber reinforced polymer (FRP) and High Density Polyethylene (HDPE) materials are being increasingly used in several applications, but especially in the construction and transportation industries. The waste management of FRP materials made with thermosetting resins is a critical issue for the composites industry because these materials cannot be reprocessed. Therefore, most thermosetting FRP waste is presently sent to landfill, in spite of the significant environmental impact caused by disposing of it in this way. Because more and more waste is being produced throughout the life cycle of FRPs, innovative solutions are needed to manage it. In this work a new composite material was fabricated by compression moulding process then the composite material was studied and tested based on fiberglass waste mixed with High Density Polyethylene Waste in different ratios of 85:15, 90:10, 95:5 (H:G). The newly fabricated composites were characterized for their mechanical properties such as compressive strength, Wear and Water absorption test as per ASTM standards. The results demonstrate the possibility of using an unexplored waste stream (glass fiber waste) as a reinforcement agent in High Density Polyethylene, which may reduce the amount of waste in landfill, while simultaneously contributing towards the circular economy.
