Deposit return systems (DRS) are the most effective way to reach the 90 percent collection target for plastic bottles – Possible misguided interpretation of separate collection target is concerning – Post-sorting of residual waste does not equal separate collection, it leads to low material quality and does not solve the pollution problem – Only DRS will enable high quality bottle-to-bottle recycling and effective littering reduction – Discussions about post-sorting could undermine the objectives of the EU Single Use Plastics Directive.
