Internet of Things (IoT) Applications in Resource Efficiency and Circular Economy

The increasing environmental pressure resulting from rapid industrial growth, urbanization, and linear “take-make-dispose” consumption patterns underscores the urgent need for sustainable and regenerative alternatives. The Circular Economy (CE) framework has emerged as a transformative model aimed at decoupling economic growth from resource depletion by promoting principles of reuse, repair, recycling, and regeneration. Within this framework, the Internet of Things (IoT) has become a key technological enabler that supports the shift toward circularity. By connecting physical assets through sensors, networks, and intelligent analytics, IoT enables continuous monitoring of resource flows, predictive maintenance of equipment, and optimization of production processes. This paper explores the synergistic relationship between IoT and circular economy practices, analyzing how digital connectivity can enhance resource efficiency across diverse sectors such as manufacturing, energy, agriculture, and urban systems. Examples include IoTenabled waste management systems that track material recovery, precision agriculture that minimizes input use, and smart grids that balance renewable energy generation with consumption. Furthermore, IoT facilitates innovative circular business models such as Product-as-a-Service, where ownership is replaced by service based use, and resource recovery systems that extend product life cycles. Despite its potential, the integration of IoT in circular practices faces challenges related to data privacy, cybersecurity, interoperability, and high implementation costs. The study concludes by emphasizing the need for policy interventions, cross-sectoral collaborations, and robust digital infrastructure to maximize IoT’s contribution to sustainability. It also proposes directions for future research, focusing on inclusive and resilient digital ecosystems that support global circular transitions.
