Circular Economy and Recycling of PVC from Electrical Cables: characterization, impact on mechanical properties and strategies for sustainable reuse

Abstract

The Circular Economy is driving the recycling of polymers, such as PVC from electrical cables, in the face of increasing inappropriate disposal in landfills. This study investigates the challenges in characterizing recycled PVC from these cables, assessing the impact on material properties. The methodology involved recycling PVC from post-consumer cables (shredding, primary separation) and comprehensive characterization (mechanical). The results revealed persistent contamination, affecting properties such as strength and processability. The analysis highlights the need for improved recycling methods and decontamination technologies to ensure the viability of recycled PVC in high-performance applications, promoting circularity and reducing reliance on virgin PVC and landfilling. The research highlights the importance of optimizing recycling and characterization processes to expand the safe and effective use of recycled PVC.
