They were cut and then crushed be- fore the depolymerization and purification stages, which allowed the monomer to be recovered. This was used to formulate a new “recycled” Elium resin with unchanged® properties. The regenerated resin was introduced into ARKEMA 4 MULTI50: the construction process to create new composite parts.
