AI Overview
Separating PVC (Polyvinyl Chloride) from PET (Polyethylene Terephthalate) in recycling is crucial, as they have similar densities (
) and cannot be easily separated by gravity. Common methods include, from AMD Color Sorter and Suny Group, automated optical/electrostatic sorting, and specialized froth flotation.

How to separate PVC from PET flakes?
Thermal Separation
In this process, a mixed stream of PET and PVC flakes is passed over a heated conveyor belt or barrel set to 180-200°C. At this temperature, PVC softens and sticks to the belt, while PET remains unaffected and rolls off into a collection bin. A stationary blade then scrapes off the PVC from the belt.Feb 28, 2025

Why don't we use plastic pyrolysis?
Simply put, pyrolysis facilities are energy intensive. They can also emit carbon monoxide, nitrogen oxides and sulfur dioxide, leading to air and water pollution. These issues have significant financial implications for plant owners who must invest in proper pollution control equipment and regularly monitor emissions.

How are PVC and PET different from each other?
It is important to note that PET is polyethylene terephthalate while PVC is polyvinyl chloride. PET is a thermoplastic polymer resin of polyester which can be moulded into different shapes to increase resistance. PET can withstand UV rays while PVC does not.
