Abstract
The present invention is in the field of an improved separation process for mixed polymers, typically provided in a waste stream, comprising a polyamide (PA) and a polyethylene terephthalate (PET). The process comprises providing a composition having a density of 50-500 gr/dm3, adding an alcohol to the composition heating the mixture to a temperature above 150° C., cooling by adding hot water, filtering with a first filter, filtering with a second filter to recover the polyamide, and recovering the polyester for further processing for depolymerization.
