3. Member States may derogate from the return and separate waste collection obligation in paragraph 1 of this Article for certain formats of waste, provided that collecting fractions of packaging waste together, or collecting packaging waste or fractions of such packaging waste together with other waste does not affect the capacity of such packaging or fractions of packaging waste to undergo preparing for re-use, recycling or other recovery operations in accordance with Articles 4 and 13 of Directive 2008/98/EC and generates output from those operations which is of comparable quality to that achieved through separate collection.
