Abstract

Un proceso para lixiviar contaminantes a partir de poliéster usado para volver a usarlo en aplicaciones en contacto con alimentos. El proceso comprendeponer en contacto una escama de poliéster usado, contaminada, con por lo menos un solvente deextracción de contaminantes capaz de hinchar al poliéster a unatemperatura suficiente para permitir la rápida difusión de dichos contaminantes a partir de dicha escama de poliéster; y separar dicho solvente de extracciónque contiene dichos contaminantes a partir de dicha escama de poliéster.
