Abstract

Se proporcionan en la presente procesos e instalaciones para utilizar uno o más materiales que contienen PET como un material de alimentación a una instalación de reciclaje químico, y en particular una instalación de solvólisis. Los materiales que contienen PET utilizados como material de alimentación pueden comprender una cantidad de material de purga solidificado que contiene PET. El material de purga solidificado que contiene PET se puede derivar de varios procesos e instalaciones, que incluyen instalaciones de recuperación de PET, fabricantes de artículos de PET y/o instalaciones de fabricación de polímero. Por ejemplo, el material de purga puede ser el material de purga solidificado de un proceso de extrusión y/o formación de pelotillas. Tales materiales de purga solidificados son generalmente indeseables o no utilizables para las instalaciones de reciclaje de PET mecánico, y típicamente se envían a rellenos sanitarios y/o incineradores. Sin embargo, los procesos e instalaciones descritos en la presente hacen uso del PET y otros plásticos presentes en estos materiales de purga solidificados de otra manera indeseables o no utilizables.
