While accurately estimating electrical and electronic waste (e-waste) generation is important for building appropriate infrastructure for its collection and recycling, making reliable estimates of this kind is difficult in Hong Kong owing to the fact that neither accurate trade statistics nor sales data of relevant products are available. In view of this, data of e-products consumption at household level was collected by a tailor-made questionnaire survey from the public for obtaining a reasonable e-waste generation estimate. It was estimated that on average no more than 80,443 tones (11.5 kg/capita) of waste is generated from non-plasma and non-liquid crystal display televisions, refrigerators, washing machines, air-conditioners and personal computers each year by Hong Kong households. However, not more than 17% of this is disposed as waste despite a producer responsibility scheme (PRS) not being in place because of the existence of a vibrant e-waste trading sector. The form of PRS control that can possibly win most public support is one that would involve the current e-waste traders as a major party in providing the reverse logistics with a visible recycling charge levied at the point of importation. This reverse logistic service should be convenient, reliable and highly accessible to the consumers.
虽然准确估算电子废物（e-waste）的产生量对于为其收集和回收建立适当的基础设施非常重要，但由于香港既没有准确的贸易统计数据，也没有相关产品的销售数据，因此很难做出可靠的估算。有鉴于此，我们通过专门设计的问卷调查从公众那里收集了家庭电子产品消费数据，以获得合理的电子废物产生量估算。据估计，香港家庭每年平均产生的非等离子和非液晶显示器电视、冰箱、洗衣机、空调和个人电脑等废物不超过 80443 吨（人均 11.5 公斤）。然而，尽管没有实施生产者责任计划（PRS），因为存在活跃的电子废物交易行业，只有不超过 17%的废物被当作废物处理。可能赢得大多数公众支持的 PRS 控制形式是，将当前的电子废物交易商作为主要一方纳入提供逆向物流的服务中，在进口点收取可见的回收费用。这种逆向物流服务应该方便、可靠，并且消费者可以很容易地获得。
