Abstract
Método para la recuperación de aluminio, celulosa y polietileno a partir de residuos de envases de tipo pack. El método comprende: a) separar, en seco, el material constitutivo del envase en dos capas (I) una primera capa (A) que comprende la capa de celulosa natural (4), la capa de celulosa tratada (5) y una lámina de polietileno (6) y (II) una segunda capa (B) que comprende el resto de las láminas de polietileno (2) y (3) y la lámina de aluminio (1); b) sumergir dicha primera capa (A) en agua y separar las capas de celulosa (4) y (5) de la lámina de polietileno (6), c) sumergir dicha segunda capa (B) en una solución adecuada para la separación de la lámina de aluminio (1) de las láminas de polietileno (2) y (3) y que no ataque ni al aluminio ni al polietileno, y d) separar la lámina de aluminio (1) de las láminas de polietileno (2) y (3). Con este método se consigue un reciclado completo de los materiales de interés contenidos en los residuos tratados.
