Digitalization and Resources Optimization in the Circular Economy: A Systemic Review of Smart Manufacturing

The circular economy is a major manufacturing sector of the economy and the ongoing proliferation of advance digital technologies and digital transformation is revolutionizing manufacturing industries and enabling more sustainable, data-driven, digitally transparent and efficient processes. Smart manufacturing technologies, such as the Internet of Things (IoT), artificial intelligence (AI), and digital twins, offer unprecedented opportunities to optimize resource usage and reduce environmental impact. Concurrently, the circular economy model promotes resource optimization, material repurpose, and sustainability by emphasizing reuse, recycling, and regeneration of materials. This study explores the various opportunities inherent in the current digital technologies and how it certainly impacts on the circular economy, it also explores the intersection of digitalization and circular economy principles, focusing on how smart manufacturing facilitates resource optimization. Through a comprehensive analysis of various digital technological advancements and industrial case studies, this paper highlights how these various digital technologies can enhance lifecycle management, improve waste reduction, and drive circular innovation towards a more sustainable society. The study adopted systemic literature review SLR in relation to the Dynamic Capability Theory DCT and Resource-Based View RBV theory to analyze existing scholarly studies on digitalization in the Circular Economy CE. This research investigate how digitalization in manufacturing can optimize resource use, reduce environmental impact, and promote circular economic practices. The study analyzed current technologies, implementation challenges, and the potential for future development in this field. The paper explored how the circular economy can benefit from digital transformation that supports sustainable practices in manufacturing, focusing on how smart technologies contribute to resource optimization within the framework of the Circular Economy. The study concludes with recommendations for stakeholders seeking to adopt sustainable practices within the Circular Economy CE in the digital age.
