ABSTRACT Nigeria faces significant environmental and health risks due to rapid Waste Electrical Electronics Equipment (WEEE) generation, estimated at 500,000 tons annually. This systematic review analyses the situation of WEEE in Nigeria, examining existing policies, regulations, emerging technologies for sustainable recycling. The analysis reveals gaps legislation, inadequate infrastructure, primitive recycling methods, resulting severe pollution risks. Emerging technologies, such as waste‐to‐energy conversion, circular economy approaches, offer potential solutions. evaluates these technologies' effectiveness sustainability Nigerian context. Recommendations policy reforms, technological innovations, stakeholder engagement are provided inform evidence‐based decision‐making promote practices Nigeria.
