Description:
The amount of post-consumer PET being recycled in the United States and Europe is constantly increasing. Today, about 23% of all PET is recycled. As the demand for post-consumer PET increases, so does the demand to produce it better and less expensively. The most detrimental contaminate to post-consumer PET is PVC. NRT has developed and marked whole bottle PVC separation systems for over three years. While this product has greatly reduced the PVC contamination levels from whole bottles or large pieces, tramp sources of PVC are still present in the PET regrind. PET processors are now required to produce material with less than 50 ppm PVC. Therefore, they require a secondary separation system or at least an online quality control system to meet their customer's needs. This Phase II proposals seeks to build upon several methods developed during Phase I which proved to technically feasible for PVC flake detection.Supplemental Keywords:
