Abstract

In a method for sorting shredder residues of metal-containing wastes, e.g., vehicle bodies, the shredder residues are separated into a shredder light fraction and a non-ferromagnetic fraction (shredder heavy fraction). A system is arranged for sorting shredder residues of metal-containing wastes, e.g., vehicle bodies. At least parts of the primary material streams produced during the sorting of the shredder light fraction and the shredder heavy fraction in preliminary processes are fed to a common, main process for final processing, at least a ferromagnetic fraction, a fraction containing non-ferromagnetic metals, a granulate fraction, a fiber fraction, and a sand fraction being produced as end products.
