Method and device for dismantling multilayer systems including at least one organic component

摘要

Method and device for delamination/dismantling of multi-layer systems SM comprising several layers including at least one organic layer, wherein the layers are separated by interfaces, characterized in that it comprises at least the following steps:Mixing the multilayer system with a fluid composed of at least one gas having the particularity of causing the swelling of at least one of the layers and one or more non-reactive liquids having the particularity of allowing the separation of each layer unitarily or of subsets of layers composing the multilayer system without degradation of the constituents of the layers, the gas/liquid fluid being raised in temperature and pressure,Recovering separately at least one or more layers or a subset of undegraded layers.
