In October of 2012, PETRA introduced a forward-looking recyclability-assessment model to provide PET producers, users and the recycling community with an advanced means of testing and evaluating new PET resin variants and innovations for their performance and recyclability in the PET resin stream.
The elective Model -- which also includes a means for assessing the recyclability of new resins having a relatively low market presents -- integrates the most progressive elements of existing European and North American recyclability initiatives without sacrificing rigorous testing benchmarks or compromising innovation.
Below are several useful documents that provide an overview of the Model, as well as the full Model document for downloading.
