Abstract

Systems and methods for increasing recyclable material recovery from automobile shredder residue (4). Embodiments include separation of automobile shredder residue with a sorting system (5) such as an air sorting system, a non-ferrous automobile shredder residue air sorter, an air-locked automobile shredder residue sorting system, a non-magnetic magnetic sorter, a substantially isotropic quantization sorting system, an air-locked Z-box air classifier, low susceptance microparticle separator, a magnetic fuzz separator, a wind tunnel system, or the like perhaps with substantially horizontal laminar air flow (7) and can be used with or without out other traditional automobile shredder residue sorting systems (16) or (15) perhaps creating additional recyclable quantities and even better separated results such as with zorba and zurik and the like.
