Abstract
Electronic waste, also known as e-waste, is any part or entire electrical or electronic product that has reached the end of its useful life. In recent years, e-waste has emerged as an issue of increasing concern as its sources, categories, collection, and treatment can lead to significant environmental damage. Moreover, there are inadequate studies about how e-waste is collected, classified, distributed, treated, and disposed of in developing countries. The objective of this study is to examine the spatial analysis of e-waste clusters (collection and treatment points), sources, and categories in Kano metropolis, Nigeria. We conducted focus group discussions (FGD) at the e-waste collection centres to estimate the number of extractors at each site. KoBo Collect Tool Box was used to generate the inventory of the e-waste collection and treatment points, while ArcGIS 10.4 was used to map the spatial distribution of the e-waste collection and treatment points and perform locational analysis. The findings revealed that repairers, scavengers, companies, institutions, and households are the major sources of e-waste in Kano metropolis. A significant portion of the e-waste collected consists of lamps, screens, small equipment, temperature exchange equipment, and information and communications devices. In Kano, however, there are few e-waste collection and treatment sites. Among the key e-waste collection sites are Kurmi and Sabon Gari Markets, while Kuka Bulukiya and PRP Gidan Ruwa serve as treatment hotspots in Kano metropolis. In spite of this, the distribution of e-waste collection points and treatment facilities is highly random due to their distance from one another.
