Abstract

La présente invention concerne un procédé de traitement d’une charge plastique comprenant des polymères, comprenant : a) une étape de dissolution comprenant la mise en contact de la charge plastique avec un solvant de dissolution, à une température de dissolution entre 100°C et 300°C et une pression de dissolution entre 1 et 20,0 MPa abs., pour dissoudre au moins une partie des polymères de la charge plastique et obtenir une solution polymère brute ; b) une étape de lavage par mise en contact de la solution polymère brute avec une solution dense, à une température entre 100°C et 300°C, une pression entre 1 et 20,0 MPa abs. et à un ratio massique entre la solution dense et la solution polymère brute compris entre 0,05 et 20,0, pour obtenir une solution polymère lavée et un effluent de lavage ; puis c) une étape de récupération des polymères, pour obtenir une fraction solvant et une fraction de polymères purifiés.
