Analysis of Regenerative Index of Depreciated Aluminum Products
Regeneration index of depreciated metal products was the index to describe sufficient degree of metal regenerated resources in metal industry. Two approaches for defining the quantities of old aluminum scrap, methods based on aluminum social stock and aluminum products use life, were given. The average use life of aluminum products in China was calculated to be about fifteen years by the weighted average method. Calculating formula for regenerative index of depreciated aluminum products was given, and regenerative index of depreciated aluminum products in the history of China and USA were analyzed.
