A method of recycling packaging material is disclosed. The packaging material comprises a multilayer material (10) comprising a metallic layer (30) and at least one polymer layer (20, 40). The method includes placing packaging material in a vat (310) containing a separation fluid (330), producing metal fragments from the metal layer (30), plastic fragments from the polymer layers (20, 40), and residual components mixture. The separation fluid includes a mixture of water, a mixture of short chain carboxylic acids, phosphoric acid, and an alkali metal hydroxide solution. |
