This study aimed to investigate the quantity of e-waste collected in Kano metropolis and its associated valuable resources. Both quantitative and qualitative data were utilized in this study. The qualitative data were obtained through focus group discussions (FGD), while the quantitative data consisted of the average estimate of e-waste collected per week at each collection point. The e-waste quantity map was produced using ArcGIS 10.3, and the valuable resources and their associations were analyzed using Nvivo 12 QSR software. The findings of this study revealed that approximately 741,120 kg (741.12 metric tons per year) of e-waste is generated annually in the study area. The identified valuable resources include ferrous metals, non-ferrous metals, information technology materials, plastics, and lead dust. It was observed that individuals engaged in e-waste activities primarily do so for the monetary value associated with these resources. Consequently, the weekly income derived from these activities ranges from as little as N10,000 ($28) to over N100,000 ($278), depending on the specific collection center and the nature of engagement. This study identified three categories of buyers for the e-waste resources, namely Nigerian agents, foreign agents, and recyclers. The research provides valuable insights into the significant quantity of e-waste generated and the valuable resources recovered in Kano metropolis, Nigeria. As a recommendation, it is crucial for the appropriate authorities to enact sustainable regulations governing the handling of collected e-waste and the exportation of valuable resources. Such measures will help maintain a sustainable environment while effectively managing the e-waste generated in this region.
