Time and motion studies were completed for hand dismantling a total of 15 incinerated and unburned junk cars representative of the more popular models during a 10-year period. Based on data derived from this study, a cost evaluation was made for processing 48 cars per 8- hour day via smokeless incinerating, hand dismantling, and baling to prepare marketable steel, cast iron, and nonferrous metal products. The evaluation indicated that an investment of $345,000 in such a plant would enable a return on investment of about 19 percent. As unburned cars cannot be profitably dismantled and open field burning is rapidly becoming illegal, a complementary study was made that led to the design and construction of a low-cost smokeless incinerator. Initial testing of this unit has established that it can effectively burn the combustibles in cars with minimal air pollution at reasonable cost. Research also has been started with the goal of devising methods for recovering marketable nonferrous metals from the nonmagnetic rejects of shredder-type plants. An air elutriation technique has proved effective for separating the metallics from the low-density nonmetallics. Future work will comprise separating and recovering the several nonferrous metals as salable products.
