Innovative Technologies And Circular Economy Strategies For Sustainable Waste Management In Nigerian Urban Centers

Abstract

Rapid urbanization in Nigeria has intensified the challenges of municipal solid waste management, contributing to environmental degradation, public health risks, and greenhouse gas emissions. Traditional linear waste management approaches characterized by 'take-make-dispose' have proven inadequate to address the growing waste volumes and complexities in Nigerian urban centers. 1). This paper examines the potential of emerging technologies, such as the Internet of Things (IoT), Artificial Intelligence (AI), and blockchain, to support circular economy strategies, that aim to reduce waste generation and enhance recycling. 2). Relying on secondary sources and case studies within Nigeria and comparable cities across the world, this study applies thematic analysis to identify technological interventions that foster circularity in waste management systems. 3). Findings reveal that while pilot projects employing smart bins, AI-enabled sorting, and blockchain-based traceability are still in pilot stage. The widespread expectation in its adoption would be hindered by infrastructural deficits, regulatory gaps, and limited stakeholder engagement. The paper argues for integrated policy frameworks that incentivize technological innovation aligned with circular economy principles, supported by capacity building among municipal authorities and communities. In advancing these technologies within a circular economy context, Nigerian urban centers can move towards sustainable waste systems that reduce environmental impact, create economic opportunities, and contribute to climate change mitigation. This research contributes to sustainability transitions literature by elucidating the nexus between cutting-edge technology and circularity in developing urban contexts.
