    Abstract: A process for treating a plastic feedstock, including a dissolution step involving placing the plastic feedstock in contact with a dissolution solvent, at between 100° C. and 300° C. and pressure of between 1 and 20.0 MPa abs, to dissolve at least a portion of the polymers of the plastic feedstock and to obtain a crude polymer solution. Also, extraction by placing the crude polymer solution in contact with an extraction solvent, at between 100° C. and 300° C., a pressure between 1 and 20.0 MPa abs and at a mass ratio between the mass flow rate of the extraction solvent and the mass flow rate of the crude polymer solution between 0.05 and 20.0, to obtain an extracted polymer solution and a spent solvent. Furthermore, recovering the polymers to obtain a solvent fraction and a purified polymer fraction.
