(137)Member States should set up return and collection systems for packaging waste, so that packaging waste is channelled to the most appropriate waste management alternative, in line with the waste hierarchy. The systems should be open for the participation of all interested parties, in particular for economic operators and public authorities. The systems should be established taking into account the environment and consumer health, safety and hygiene. Return and collection systems should also be accessible and applicable for the packaging of imported products under non-discriminatory provisions.
