The global electronic waste (e-waste) output is increasing at an alarming pace, albeit with limited management practices, resulting in the release of toxic anthropogenic elements that threaten the environment and public health. The linear economic model, which follows the take-make-consume-dispose has shaped the global economy. In contrast, the circular economy reduces wastage, recirculates raw materials, and extends the lifespan of products through repairing, refurbishing and remanufacturing. This reduces supply chain risks and product supply disruptions and creates formal jobs. This systematic literature review evaluates how the knowledge economy and modernisation growth have contributed to the e-waste burden, and how the circular economy can mitigate environmental and health effects. The study evaluates the impact of the circular economy and the e-waste problem. It identifies the research landscape, the key research clusters, relevant topics, and research hotspots from research output from the 949 publications selected from the Scopus database published from 2014 to 2023. The analysis involved quantitative descriptions of several metrics related to the research outputs. The analysis also involved creating network and density graphs using VoSViewer and generating the ten key topics and a word cloud using Provalis WordStat. The study also highlights the conceptual developments and current and future research trends. The findings show that research outputs increased substantially from two in 2014 to 257 in 2023 and citations grew astronomically, from one in 2014 to 8409 in 2023. The analysis reveals five research clusters: material management and resource recovery, business practices and circular economy strategies, technology integration and sustainability, recycling challenges, and environmental health and sustainable practices. The study recommends that emerging economies should embrace the circular economy and integrate the informal sector for e-waste collection, sorting, and less complex recycling, while the formal sector conducts high-end recycling.
