Sales of electrical and electronic equipment are increasing dramatically in developing countries. Usually, there are no reliable data about quantities of the waste generated. A new law for solid waste management was enacted in Brazil in 2010, and the infrastructure to treat this waste must be planned, considering the volumes of the different types of electrical and electronic equipment generated. This paper reviews the literature regarding estimation of waste electrical and electronic equipment (WEEE), focusing on developing countries, particularly in Latin America. It briefly describes the current WEEE system in Brazil and presents an updated estimate of generation of WEEE. Considering the limited available data in Brazil, a model for WEEE generation estimation is proposed in which different methods are used for mature and non-mature market products. The results showed that the most important variable is the equipment lifetime, which requires a thorough understanding of consumer behavior to estimate. Since Brazil is a rapidly expanding market, the "boom" in waste generation is still to come. In the near future, better data will provide more reliable estimation of waste generation and a clearer interpretation of the lifetime variable throughout the years.
发展中国家电气电子设备的销售量正在急剧增长。通常，关于产生的废物数量没有可靠的数据。2010 年，巴西颁布了一项固体废物管理新法律，必须根据所产生的不同类型电气电子设备的数量来规划处理这些废物的基础设施。本文回顾了有关废物电气和电子设备（WEEE）估算的文献，重点是发展中国家，特别是拉丁美洲。它简要描述了巴西目前的 WEEE 系统，并提出了 WEEE 产生的最新估算。考虑到巴西可用数据有限，提出了一种 WEEE 产生估算模型，其中对成熟和不成熟市场产品使用了不同的方法。结果表明，最重要的变量是设备寿命，这需要深入了解消费者行为才能进行估算。由于巴西是一个迅速扩张的市场，废物产生的“热潮”尚未到来。在不久的将来，更好的数据将提供更可靠的废物产生估算，并对多年来的寿命变量进行更清晰的解释。
