Redesigning Urban Infrastructure for Circularity: The Role of Smart Cities in Reducing Waste

Abstract

Rapid global urbanization has prompted cities to rethink their development strategies in the context of sustainability. One of the most promising paradigms is the transition toward a circular economy (CE), where resources are reused, recycled, and regenerated. This perspective article explores how the integration of smart city technologies, such as the Internet of Things (IoT), Artificial Intelligence (AI), and data analytics, can drive urban infrastructure toward circularity. Through the process of analyzing current research and case studies, the article highlights the potential of these technologies to reduce waste, optimize resource use, and enhance energy efficiency in urban settings. This article focuses particularly on the role of smart waste management, intelligent building design, and real- time data analysis in fostering circular practices in cities. Through these themes, this article offers insights into how smart cities can bridge the gap between linear urban development models and a sustainable, regenerative urban economy.
