The potential for economic recycling of automobiles has been increased by recent research into the two principal automotive scrap handling procedures of (1) shredding with byproduct recovery from nonmagnetic rejects and (2) incineration, hand dismantling, and baling or shredding. Development of alternative procedures of sink-float and water classification for concentrating the nonferrous metal contents of the nonmagnetic reject products could benefit the economics of shredder operation. The use of cryogenics for separating brittle die cast from malleable aluminum and copper and for separating insulation from copper wire also appears promising for enhancing the recycling of shredded automotive materials. The economics of incineration operation are made more attractive by demonstrating the feasibility of burning mashed cars, thus increasing the capacity of the test incinerator from 50 to over 80 cars per day. An evaluation of alternate procedures for recovering the values in generators and starters shows mechanically assisted hand dismantling is preferable to salt sweating, ammoniacal leaching, or cryogenic techniques.
