Abstract
La presente invención se refiere a un método para el reciclaje de un residuo textil (ST) que comprende un componente celulósico y un componente de poliéster, que comprende los siguientes pasos: - un paso de despolimerización (110), que comprende someter el residuo textil (ST) a una reacción de despolimerización del componente de poliéster mediante hidrólisis básica por medio de una mezcla solvolítica (MS) que comprende un hidróxido de metal alcalino (IMA) y al menos un disolvente de reacción orgánico soluble en agua (SOIR) hasta obtener una mezcla bifásica (MB) que comprende una fase sólida inicial (ESI), que contiene una sal de ácido tereftálico (SAT) y fibras celulósicas, y una fase líquida inicial (ELI), que contiene el disolvente de reacción orgánico soluble en agua (SOIR); - un primer paso de separación sólido-líquido (210), que comprende la eliminación de al menos una parte de la fase líquida inicial (ELI) de la mezcla bifásica (MB); - un paso de tratamiento con disolvente orgánico (220), en donde la fase sólida inicial (ESI), después del primer paso de separación sólido-líquido (210), se trata con un disolvente de lavado orgánico (SOL) hasta eliminar, de la fase sólida inicial (ESI), uno o más posibles contaminantes presentes en la misma y obtener una fase sólida purificada (ESP) que contiene la sal de ácido tereftálico (SAT) y las fibras celulósicas; - un segundo paso de separación sólido-líquido (230), en donde la fase sólida purificada (ESP) se separa del disolvente de lavado orgánico (SOL) y del uno o más posibles contaminantes disueltos en la misma; - un paso de tratamiento con agua (240), que comprende poner la fase sólida purificada (ESP) en contacto con el agua de lavado (AL) hasta solubilizar la sal de ácido tereftálico (SAT) contenida en la misma y obtener, mediante la eliminación de la última, una fase sólida final (FSF) que comprende las fibras celulósicas.
