Process for recycling articles based on a fiber reinforced polymer
Abstract:
Process for recycling a fiber reinforced polymer article, according to which the article, eventually cut in fragments, is dissolved in a solvent capable of dissolving the polymer but not the fibers and which is susceptible of forming an azeotrope with water, forming a solution; the fibers are recovered from the solution; the fibers are washed with solvent by putting them in the form of a slurry in the solvent and by agitating the slurry and/or by making the solvent circulate through it; the washed fibers are recovered from the slurry; and the recovered fibers are submitted to a stripping with steam in order to substantially remove the solvent.
