Recycling Process for Number 5 Plastics
The recycling of Number 5 plastics, primarily made from polypropylene (PP), involves several key steps designed to ensure the material can be effectively reused in new products. The process begins with collection and sorting, where Number 5 plastics are separated from other resin types to prevent contamination. This sorting is typically done at material recovery facilities (MRFs) using both manual and automated methods such as near-infrared (NIR) technology.
Once sorted, the polypropylene is cleaned to remove any residues, labels, or adhesives. This cleaning phase often involves washing with detergents and rinsing to prepare the plastic for processing. After cleaning, the material is shredded into smaller flakes or pellets to facilitate melting and reforming.
The shredded polypropylene is then melted down and extruded into pellets, which can be sold to manufacturers to create new products. The recyclability of Number 5 plastics depends heavily on the purity of the feedstock and the absence of additives that can complicate processing. Due to polypropylene’s relatively high melting point and chemical resistance, recycled Number 5 can be used in a broad range of applications.
