Some time ago automobiles and other transportation vehicles were almost exclusively made from iron and steel. Today fierce competition and governmental push for lighter, more fuel-efficient vehicles has led to the introduction and continued implementation of aluminum, plastics and a host of various composites. The importance of considering more carefully the specifications for automobile materials is demonstrated by going into some details: The type or grade of up-to-date steel and aluminum material is given. At the same token, the second most-commonly used automotive material, plastics are listed. The metal recovery of one of the most modern shredder companies (HURON VALLEY STEEL CORP) with its sophisticated sink float and eddy-current separation system is explained and the difficulties to separate the various metal grades. Chemical composition limits of various material grades of e.g. aluminum makes obvious that metal recycling includes some downcycling. By giving sources of information for scrap specifications as well as base prices for metal scrap, primary metals and a price watch of waste plastics and commodity plastics, the market or money factor is brought into discussion. It is believed that this aspect is hardly ever discussed in depth, and that the consequences for the small- and medium-sized enterprises are not faced. It is believed that recovery of plastics from ELV will never pay, and from the point of view of the life-cycle of a car, material recovery is less efficient than energy recovery: Incineration of all plastic material, i.e. the shredder residue is the reasonable recycling solution.
