The invention concerns a method for preconcentration of upgradable polymer materials derived from a residue of shredded end-of-life consumable goods which consists in treating the residue in successive steps comprising sorting, aeraulic separation, crushing and final aeraulic separation, to eliminate therefrom the major part of contaminating materials such as metals, glass, rubber, sand and the like and to obtain a preconcentrated fraction of upgradable polymer materials for recycling. The preconcentration method preferably enables 85 wt. % of upgradable materials to be obtained per recycling treatment.
Procédé de préconcentration de matériaux polymères valorisables issus d'un résidu de broyage d'articles consommables en fin de vie, tels que automobiles, matériel informatique, matériel électroménager qui consiste à traiter le résidu par des étapes successives comportant criblage, séparation aéraulique, broyage et ultime séparation aéraulique, pour en éliminer majoritairement les matériaux contaminants tels que métaux, verre, caoutchouc, sable ou autres et obtenir une fraction préconcentrée en matériaux polymères valorisables par recyclage. Le procédé de préconcentration permet d'atteindre préférentiellement au moins 85% en poids de matériaux polymères valorisables par recyclage.
