PROCÉDÉ DE TRAITEMENT DES DÉCHETS CRÉÉS PAR RECYCLAGE DE PAPIER PROVENANT DE CARTONS DE BOISSON USAGÉS

摘要

The submitted invention describes a method for processing, and gaining value from, waste which is created by recycling paper from used beverage cartons, and a processing line for performing this method. In Phase I, the flake size of the input material (I-A) is reduced, the rough waste (I-B) and dust waste (I-C) removed from it, the thus treated input material (I-A) is separated into fraction (I-D), containing mainly non-foil plastic, and fraction containing mainly PE foil and PE+AL foil. In Phase II, fraction containing mainly PE foil and PE+AL foil undergoes washing in a water-based formic acid solution and is separated into fraction (II-A), containing mainly polyethylene, and fraction (II-B), containing mainly aluminium. During Phase III, fraction (II-B) is processed into aluminium and in Phase IV, fraction (II-A) is processed into polyethylene granules, then, in Phase V, fraction (I-D) has the admixture removed and is processed into regrind or granules.
