Material and Energy Beneficiation of the Automobile Shredder Residues

Although vehicles represent a main key of our modern society, they affect our environment via the energy and resource consumption, waste generation during their manufacturing as well as greenhouse gas emissions all along their use. Further, hazardous residues are produced at the end-of-life vehicles “ELV”. After collection and dismantling, the remainders of the ELV are directed to shredding operator followed by a series of mechanical and physical separations in order to recover the ferrous and non-ferrous metals. The residue of the shredding process, called automobile shredder residue “ASR” represents about 20–25% of the ELV. The ASR, while toxic enough to be classified as hazardous waste, could be considered as material and energy sources.
