Abstract：
In this study, the generation of domestic waste electrical and electronic equipment (WEEE) and waste printed circuit board (WPCB) were estimated, from 2015 to 2030. Based on the number of EEE put on the Brazilian market, the possession rate in the Brazilian households and obsolescence amounts of five EEE types were estimated using time series. The results show that, between 2015 and 2030, the quantity of WEEE generated per year will increase from 131.87 kt to 195.22 kt. In this period, WPCB generation will stay around 10% of WEEE generation. Additionally, this study shows that the urban mining potential of the materials recoverable from WPCB can be an important revenue source, with environmental benefits deriving from energy savings and a reduction in CO2 emissions. The results of this study provide a quantitative basis that may help decision makers develop strategic policies for WEEE management, considering material circularity.
摘要：
在这项研究中,估计了生活废物电气和电子设备（WEEE）和废物印刷电路板（WPCB）的产生，从2015年到2030年。根据巴西市场上的EEE数量，使用时间序列估计了巴西家庭的拥有率和五种EEE类型的报废量。结果表明,从2015年到2030年，每年产生的WEEE数量将从131.87kt增加到195.22kt。在这个时期,WPCB发电量将保持在WEEE发电量的10%左右。此外,这项研究表明，从WPCB回收的材料的城市开采潜力可以成为重要的收入来源，从节约能源和减少二氧化碳排放中获得环境效益。这项研究的结果提供了一个定量的基础，可以帮助决策者制定WEEE管理的战略政策，考虑材料的圆度。
