Abstract

Se describe una novedosa técnica para tratar poliéster desechado por consumidores, para reutilizarlo en aplicaciones en las que entra en contacto con alimentos. El proceso comprende el poner en contacto hojuelas de poliéster desechadas por consumidores, contaminadas, con cuando menos un disolvente de extraccion que es soluble en dichas contaminadas, a una temperatura suficiente para permitir la rápida difusion de los contaminantes desde las hojuelas de poliéster; y remocion de dicho disolvente de extraccion conteniendo dichos contaminantes procedentes hojuelas de poliéster.
