Abstract

Se proporcionan en la presente métodos y sistemas para separar desecho de plástico mezclado. Los métodos generalmente comprenden separar el desecho de plástico mezclado en una corriente enriquecida con PET y una o más corrientes agotadas de PET. La separación se puede realizar utilizando las combinaciones de dos o más etapas de separación por densidad. Las etapas de separación por densidad ejemplares incluyen separadores de hundimiento-flotación y separadores de fuerza centrífuga. Las corrientes enriquecida con PET y agotada de PET se pueden recuperar y/o dirigir a procesos de reciclaje químico corriente abajo.
