Use and disposal of large home electronic appliances in Vietnam 总被引:1,自引:1,他引:0

In this study, e-waste flows of five large home appliances (color televisions, refrigerators, washing machines, personal computers,
and air conditioners) in Vietnam are investigated. A social survey was performed to investigate the situation on using appliances
in households as well as on the disposal of appliances by the first users. Future quantities of e-waste were estimated using
a model that combines use of the Weibull distribution, the logistic function, and the population balance model. It was forecast
that about 3.86 million appliances, or 114 000 tons, will be discarded in 2010, and about 17.2 million appliances, or 567
000 tons, in 2025, showing a rapid increase of e-waste in the near future. 相似文献

In this paper, utilizing the existing primary copper smelter process for the recovery of metals from waste printed circuit boards (PCBs) is proposed as an alternative to the current backyard operations in developing countries. The Model for Evaluating Metal Recycling Efficiency from Complex Scraps (MEMRECS) concept is introduced as a tool for the evaluation of the eco-efficiency of metals recovery from waste PCBs. Based on the MEMRECS approach, the relative contribution of every metal fraction to the recyclability of the whole product is estimated. Thereby, gold content is identified as a key factor strongly influencing the efficiency of metals recovery from waste PCBs. Furthermore, it could be used as an indicator for the categorization of waste PCBs before feeding them into the recycling process. Finally, an integrated process is proposed to optimize the eco-efficiency of metals recovery from waste PCBs in developing countries. 相似文献
