Characterization of Various ASR Streams 1999-01-0670

About 11 million vehicles are scrapped each year in the United States. Most of these vehicles are recycled by automotive dismantlers and shredders. Presently, about 95% of the ferrous and non-ferrous metals present in vehicles (75% of the total vehicle weight) are recovered. The remainder of the scrapped vehicles (non-metal portion known as automotive shredder residue-ASR) is landfilled, generating up to 3 million tons of waste per year. In order to increase the efficiency of recovery of both ferrous and non-ferrous metals from the shredded vehicles, numerous developments have been made by the shredders in separation technology recently. This paper is an update of our previous paper and contains in-depth characterization of the various ASR streams.
