High poverty rate and the need to use information communications technology facilities in the information age compel Nigerians to patronize used, cheap and near-end-of-life electronic waste (e-waste) items that soon become unserviceable and discarded. Dearth of infrastructure for e-waste management and control leads to improper e-waste disposal practices that aggravate the existing environmental degradation and public health challenges. This situation calls for remediation. Unlike other toxic chemical components of e-waste materials, beryllium oxide and lead are both hazardous and occur in significant quantities in e-waste materials. This study adopted experimental methods for simulation of innovative green chemistry models for treatment of municipal e-waste materials for beryllium oxide and lead extraction, resource recovery, repair, recycling and reuse, as well as choice for the process reactors. Four green chemistry models resulted, namely, green chemistry beryllium oxide model for municipal e-waste treatment for resource recovery, repair, recycling and reuse (GCBOMME-WTR5); green chemistry lead model for municipal e-waste treatment for resource recovery, repair, recycling and reuse (GCLMME-WTR5); green chemistry acid-precipitation of lead model for municipal e-waste treatment for resource recovery, repair, recycling and reuse (GCAPLMME-WTR5); and green chemistry solvent-extraction recycling of lead model for municipal e-waste treatment for resource recovery, repair, recycling and reuse (GCSERLMME-WTR5). Pilot scale and subsequent commercial application of these models were recommended for remediation of e-waste related pollution and the attendant environmental and health hazards in Nigeria. The study is relevant, novel and important in the global e-waste problem, and the critical need for circular economy because it identified a serious ongoing problem and applied green chemistry models to address it.

尼日利亚用于市政电子废物处理的绿色化学模型，用于资源回收，修复，回收和再利用

高贫困率和信息时代对使用信息通信技术设施的需求迫使尼日利亚人光顾用过的，廉价的和寿命将尽的电子废物（e-waste）物品，这些物品很快变得无法使用并被丢弃。电子废物管理和控制基础设施的缺乏导致了不正确的电子废物处置做法，加剧了现有的环境恶化和公共卫生挑战。这种情况需要补救。与电子垃圾材料中的其他有毒化学成分不同，氧化铍和铅都是有害物质，在电子垃圾材料中大量存在。这项研究采用了实验方法来模拟创新的绿色化学模型，以处理用于氧化铍和铅提取，资源回收，修复，回收和再利用，以及工艺反应器的选择。产生了四个绿色化学模型，即用于市政电子废物处理的绿色化学氧化铍模型，用于资源的回收，修复，回收和再利用（GCBOMME-WTR5）；用于资源回收，修复，回收和再利用的市政电子废物处理的绿色化学铅模型（GCLMME-WTR5）；用于市政电子废物处理的绿色化学酸沉淀铅模型，用于资源回收，修复，回收和再利用（GCAPLMME-WTR5）；以及用于市政电子废物处理的铅模型的绿色化学溶剂提取回收利用，用于资源回收，修复，回收和再利用（GCSERLMME-WTR5）。建议对这些模型进行试点规模和随后的商业应用，以补救尼日利亚与电子废物相关的污染以及随之而来的环境和健康危害。该研究在全球电子废物问题以及循环经济的迫切需要中具有相关性，新颖性和重要性，因为它发现了一个严重的持续问题并应用了绿色化学模型来解决这一问题。
