Recycling initiative RecyClass (Brussels; www.recyclass.eu) has published a new evaluation protocol to test the recyclability of packaging made out of polystyrene. The protocol outlines a comprehensive methodology for laboratory testing of extraordinary packaging and its effects on recycled PS, and adds on to existing protocols for HDPE and PP containers.

The document also allows for evaluating the ability to reclaim different components, including non-PS layers, coatings, attachments, closure systems, labels, adhesives, printing inks technologies, and compatibilisers.

The protocol, according to RecyClass, is ideal for companies wanting to discover if their rigid PS packaging, such as food-contact containers, is compatible with post-consumer recycling in Europe.

David Eslava, chairman of the RecyClass PS Technical Committee, said, “Ensuring recyclability of PS packaging, beyond increasing its collection, is indispensable to improve its end-of-life management and to unlock a new market for recycled materials.”
