METHOD AND DEVICE FOR DISMANTLING MULTILAYER SYSTEMS INCLUDING AT LEAST ONE ORGANIC COMPONENT

摘要

The invention relates to a method and device for delaminating/dismantling multilayer systems SM comprising a plurality of layers, including at least one organic layer, the layers being separated by interfaces, characterised in that it comprises at least the following steps: mixing the multilayer system with a fluid made up of at least one gas having the specificity of causing at least one of the layers to swell and one or more non-reactive liquids having the specificity of allowing each layer individually or subsets of layers which make up the multilayer system to be disconnected without damaging the components of the layers, the gas/liquid fluid being brought to the required temperature and pressure; and separately recovering at least one or more layers or a subset of layers which are undamaged.
