SEATTLE (Waste Advantage): The Institute of Scrap Recycling Industries (ISRI) Board of Directors recently passed a series of changes to its policy positions, as well as a new policy on degradable additives in plastics packaging. The new policy is a result of the confusion over the use of terms “bio-degradable,” “oxo-degradable,” or “photo degradable” to describe plastics containing degradable additives, when in fact, evidence does not support their use meet common definitions of these terms.
Degradable additives are chemical compounds that are often incorporated in conventional plastics such polyethylene (PE), polypropylene (PP), polystyrene (PS), polyethylene terephthalate (PET) and polyvinyl chloride (PVC) during the converting process from polymer pellets to final products. The terms “bio-degradable,” “oxo-degradable,” or “photo degradable” when used in relation to use with a plastic item may not be supported by tests conducted by third parties using standards and protocols as those published by ASTM, ISO and other standard making bodies. In addition, plastics that contain degradable additives can harm plastic recycling as these additives may be mixed unknowingly with non-degradable plastic and cause the resulting feedstock to be significantly compromised.
As a result, ISRI:
