Nowadays, the electrical and electronic products are a crucial commodity for different purposes of daily life and they are multiplying five times faster than human like mobile phones, which has reached zero to 7.2 billion in only three decades. A 5-10% yearly increase in the amount of used electrical and electronic equipment that are disposed of prudently can cause environmental hazards that have an aversive effect on human health, marine life, contamination of groundwater, and reduces soil's fertility. Management of this enormous influx of electrical and electronic waste is a challenge for developing countries like Bangladesh with barebones solid waste management infrastructure. Inadequacy of public awareness, policies and poor budget in the field of waste management are few of the key factors behind this delineating scenario. In this study, the picture electrical and electronic waste productions in Bangladesh along with the recent E-waste management systems have been presented comprehensively. Based on the study, it was concluded that most of the adapted E-waste management methods are conversational and detached from current technological capability. A set of sustainable E-waste management system has been suggested along with the challenges, which might appear during the implementation of these strategies. Successful implementation of these suggested systems would advance the quality of E-waste management in Bangladesh increasing the current 35% overall E-waste recycling rate and offer enormous energy from the waste.
如今，电子产品已成为日常生活中不可或缺的重要商品，其数量的增长速度比人类自身还要快五倍，仅在三十年内，手机的数量就从 0 增长到了 72 亿。如果每年妥善处理的废旧电器和电子设备数量增加 5%至 10%，可能会对人类健康、海洋生物、地下水污染和土壤肥力造成危害。对于孟加拉国等发展中国家来说，管理如此大量的电子垃圾是一个挑战，因为这些国家的固体废物管理基础设施薄弱。公众意识不足、政策和废物管理领域预算不足等都是造成这种局面的关键因素。在这项研究中，全面介绍了孟加拉国的电子垃圾产生情况以及最近的电子垃圾管理系统。根据研究结果，大多数采用的电子垃圾管理方法都是传统的，与当前的技术能力脱节。本文还提出了一套可持续的电子垃圾管理系统，并预测了在实施这些战略时可能出现的挑战。成功实施这些建议的系统将提高孟加拉国电子垃圾管理的质量，将目前 35%的总体电子垃圾回收率提高，并从废物中获得巨大的能源。
