Abstract:The average and total possession amounts of typical electrical electronic products were estimated using the logistic model. The generation amount of typical electronic waste and waste printed circuit board (WPCB) were estimated using the population balance model (PBM). Stock of metal resources in WPCB and exploitation potentiality prediction were analyzed with substance flow analysis (SFA). The results indicate that the total possession amount of television, computer and mobile phone are going to reach to 776.49 million, 463.65 million, 1702.84 million, respectively, in 2030. Generation amount of the five typical electronic waste and WPCB are going to reach to 280.73×104 and 29.92×104 t, respectively, in 2030. The stock quantities of gold, silver, copper, tin, lead and strontium contain in WPCB will reach to 119.5, 305.7, 60915, 7897, 5189 and 101.5 t, respectively, in 2030. In the period from 2015 to 2030, the generation amount of typical electronic waste and WPCB are growing with constantly updating function, design of electronic products and gradual shortening of service lifespan. But the growing speed will slow down, compared with the past 15 years (2001-2015).
Key words: electronic waste; waste printed circuit board; population balance model; substance flow analysis; metal resources; exploitation potentiality prediction
