Environmental risk assessment for an informal e-waste recycling site in Lagos State, Nigeria
It has been recognised that the informal E-waste recycling may pose a risk to human health and the environment, this study aims to evaluate the e-waste contamination and the environmental and human health impact of informal e-waste recycling on the exposed population using the risk assessment …

Reverse logistics and large-scale material recovery from electronics waste
Waste consolidation is a crucial step in the development of cost-effective, nation-wide material reclamation networks. This thesis project investigates typical and conformational tendencies of a hypothetical end-of-life electronics recycling system based in the United States. Optimal waste …

Exploring the potential for local end-processing of e-waste in South Africa
E-waste is one of the fastest-growing waste streams in the world, and South Africa (SA) is no exception. This is driven by increased consumer demand and access to electrical and electronic equipment, in addition to perceived equipment obsolescence, and rapid advancements in technology. E-waste …

An investigation of the distribution, fractionation and bioaccessibility of potentially toxic elements in urban soils of Lagos, Nigeria
… activities such as foundries, dumpsites, and e-waste recycling sites were often highly contaminated. Principal component and cluster analysis identified Cr-Fe-Mn-Ni and Cu-Pb-Zn groupings. Correlation coefficient analysis further confirmed these relationships; grouping the lithogenic PTE …

RECYCLING OF PRECIOUS METALS FROM WASTE PRINTED CIRCUIT BOARDS VIA A COMBINATION OF PYRO AND HYDROMETALLURGICAL PROCESSES
Electronic waste (e-waste) has emerged as a critical issue in our technologically advanced society due to the escalating rise of electronic devices, necessitating the development of innovative recycling techniques. Printed Circuit Boards (PCBs) are among the most complex components of e-waste, …

Towards the sustainable management of electronic waste in Nigeria: South Africa as a model
The trade in and management of electronic waste in Nigeria is significant because of the volumes of e-waste generated from second-hand electrical and electronic equipment (EEE) imports. Current and future e-waste discourse advocate the need for, not only an effective legislative approach, but also …

An evaluation on electronic waste management and product stewardship programs in North America
Electronic waste (E-waste) has been extensively investigated by researchers throughout the globe, however specific research trends in North America (NA) are yet unknown. The first part of the study attempts to present an up-to-date bibliometric view of e-waste studies and to identify the research …

Recovery of rare earth elements (REE) from waste printed circuit boards (WPCBs) through heterotrophic bioleaching
… (REE) from secondary sources, such as electronic waste (e-waste), is increasingly gaining attention as these elements are at high supply risk, and the environmental impacts of mining them are of concern. Global REE recycling rates remain below 1%. Waste printed circuit boards (WPCBs) represent a …
