A method for recovering fuel substance and providing an alternative periodic cover material for landfills by separating materials in a salvage operation. A non-sorted material stream including metallic and non-metallic components, which preferably includes automobile scrap, is fed to a shredder. After shredding, the non-sorted material stream is separated. The non-sorted material stream is first separated into two streams, namely, a heavy material stream and a light material stream. The heavy material stream is conveyed to a magnetic separator where ferrous metals are separated from non-ferrous materials. The light material stream is passed under a cross belt magnetic separator where the light ferrous metals are separated. The remaining light material stream is further separated to remove non-ferrous metal material. The remaining non-metallic material can be used as a fuel substance or as a cover material for landfills.
