PETRA introduces new model for assessing the recyclability of PET resins


The PET Resin Association (PETRA) has unveiled a new assessment model that includes testing and evaluation criteria for the recyclability of newly developed PET resins used in manufacturing PET bottles and containers.

The elective model, which also includes a means for assessing the recyclability of new resins having a relatively low market presence, was designed to combine the most progressive elements of existing European and North American recyclability initiatives without sacrificing rigorous testing benchmarks or compromising innovation, according to PETRA.

In North America, the Association of Postconsumer Plastic Recyclers (APR) has developed its long-standing PET Bottle Critical Guidance document. Current recyclability guidelines in the U.S. restrict resin testing to concentrations of 25% or 50% to minimize processing challenges to the broadest possible range of recyclers.
