Process for joint recycling of composite items based on a thermoplastic polymer matrix

Abstract

A process for recycling a first article to be recycled including a composite material based on a fibrous reinforcer and a thermoplastic, preferably (meth)acrylic, polymer matrix, wherein the recycling process includes the following steps: introduction of the first article into a system suitable for the recycling of thermoplastic polymer, introduction, into the system suitable for the recycling of thermoplastic polymer, of a second article to be recycled including a thermoplastic polymer resin, and not including any fibrous reinforcer, heating of the articles to be recycled at a given temperature, in the system suitable for recycling thermoplastic polymer, so as to depolymerize the thermoplastic, preferably (meth)acrylic, polymers, and to form base monomers of the thermoplastic polymers, and recovery of the constituent base monomers of the thermoplastic polymers.
