FIELD: recycling technologies.
SUBSTANCE: invention relates to a technology for recycling packaging material. Packaging material contains multi-layer material containing at least a metal layer and at least one polymer layer. A method includes placing packaging material in container 310 containing separation fluid 330 for the production of a mixture of metal scraps of the metal layer, plastic scraps of the polymer layer, and residual components. Separation fluid 330 for separating multi-layer material contains a mixture of water, short-chain carboxylic acid, phosphoric acid, as well as alkali metal hydroxide, while separation fluid has a pH value from 2 to 4, to separate multi-layer material and reduce dissolution of the metal layer.
EFFECT: recycling packaging material.
