(46)The separate collection of plastic waste is essential, as it has a direct, positive impact on the collection rate, on the quality of the collected material and on the quality of the recyclates. It enables high-quality recycling and boosts the uptake of quality secondary raw materials. Moving closer to a ‘recycling society’ helps to avoid waste generation and encourages the use of waste as a resource, while avoiding locking in resources at the lower levels of the waste hierarchy with detrimental effects on the environment and disregarding environmentally sound management of waste. Separate collection also avoids mixing hazardous and non-hazardous waste, ensuring the safety of the waste and of its shipment, and avoids pollution, as provided by international rules such as the Basel Convention on the control of transboundary movements of hazardous wastes and their disposal 22 of 22 March 1989, the United Nations Convention on the Law of the Sea of 10 December 1982 23 , the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter, done in London on 29 December 1972, and its 1996 Protocol, and Annex V to the International Convention for the Prevention of Pollution from Ships of 2 November 1973 (MARPOL), as modified by the Protocol of 1978 relating thereto.
