(FR) PROCEDE DE RECUPERATION DE MATIERES UTILES PROVENANT DE DECHETS D'EMBALLAGES STRATIFIES MULTICOUCHE
Abstract: front page image
(EN)A process of recovery of useful constituents from multi-layered laminated fragments of packaging industrial refuse in sheet, tube or shredded form from each other as separate constituents comprising treating the comminuted fragments with an inorganic base solution, so as to dissolve the laminated metal aluminium to subsequent recoverable aluminium salts, eventuating primarily as sodium aluminate wherein from even a medicine like aluminium hydroxide gel passing pharmacy grade assay, and recover the polyethylene plastics in as it is physical condition and washing the same.
(FR)L'invention concerne un procédé de récupération de constituants utiles provenant de fragments stratifiés multicouche de déchets industriels d'emballages sous forme de feuille, de tuyau ou de morceaux broyés, comme constituants séparés. Le procédé comporte les étapes consistant à : traiter, à l'aide d'une solution basique inorganique, les fragments réduits en morceaux afin de dissoudre l'aluminium stratifié en sels d'aluminium pouvant être récupérés ultérieurement, principalement de l'aluminate de sodium, à partir duquel un gel d'hydroxyde d'alumine de type médical ou de qualité pharmaceutique peut être obtenu ; et récupérer le polyéthylène ayant gardé ses propriétés physiques et le laver.
