This study seeks to advance understanding of the problem of waste disposal by reviewing one element of the problem, the reuse of nonferrous scrap. The available literature was reviewed and analyzed. The report covers two major nonferrous metals--copper and aluminum. Although they compete in many markets, these two nonferrous metals prove quite different when viewed in the perspective of this study. Aluminum has shown rapid growth and steadily expanded uses in which it could compete. Copper in contrast has shown much less change. The difference in growth is necessarily a major factor in effecting the role of scrap in the total availability of a metal. At least some portion of the scrap consists of material from products that were made many years ago. A rapid growth rate for primary products implies that this scrap will be a much smaller fraction of total availability than a product with lesser growth. In practice, the relationship also depends upon the rate of recovery of this material. Copper recovery proves considerably easier than that of aluminum.
