These updated guidelines detail common recycling practices, with a focus on mechanical recycling processes as these are considered to represent the greatest potential health concern for food contact applications. They discuss key aspects of the recycling process such as the: limitations of use, source of feedstock (materials to be recycled), efficiency of the recycling process in the removal of chemical contaminants. These guidelines will assist recyclers, manufacturers and sellers of plastic materials in determining the acceptability and use of post-consumer recycled (PCR) plastics in food packaging applications.
