A method for recycling of packaging material (300) is disclosed. The packaging material (300) comprises a multiple layer material (10) comprising a metal layer (50), at least one polymer layer (20, 40, 60) and, optionally, a paperboard layer (30). The method comprises placing the residual waste in a vat (360) comprising a separation fluid (375) to produce a mixture of metal shreds from the metal layer (50), plastic shreds from the polymer layer (20, 40, 60) and residual components. The separation fluid comprises a mixture comprising at least one swelling agent and at least one carboxylic acid. |
