Properties of Simulated Plastic Waste Mixtures in Upcycling Processes: An Experimental Evaluation.

ABSTRACT: Current production of virgin plastics stands at approximately 0.4 billion tonnes annually, with significant applications in packaging, construction, and the automotive industry. Despite the utility of plastics, their waste management remains a challenge. This study focuses on upcycling plastic waste (PW) through mechanical recycling, which adds value to discarded plastics and aligns with sustainable practices. We have investigated the mechanical and thermal properties of ternary and quaternary blends of the most common polyolefin polymers, low-density polyethylene and polypropylene (PP), simulating typical PW mixtures. The blends were prepared using twin screw extrusion for melting, mixing, and strand extrusion. The strands from the extruder were guided through a water bath, optionally dri
