Abstract

Study on the generation amount and the metal stock of obsolete computers is important for building a reasonable recycling system of waste. In this study, the average possession and sales of computers, the generation amount and the deposit of valuable metals in obsolete computers were predicted using logistic model, population balance model and material balance principle, respectively. The results indicated that the generation amount of obsolete computers in China was about 368 million units in 2030. The stock quantities of gold, silver and palladium contained in obsolete computers would reach 157.74, 478.12 and 46.72 tons, respectively. And the stock quantity of copper would reach 109.1 thousand tons.

Key words： obsolete computers generation amount metals sources stock Logistic model
