| Abstract |
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.
