As global integration continues to deepen and environmental requirements become increasingly stringent, the transition toward a circular economy is emerging as a defining trend of our time. This shift calls for new approaches to improving productivity, optimizing supply chains, and reducing carbon emissions in a sustainable manner. In this context, Hanoi University of Industry (HaUI) hosted the 3rd International Conference on Sustainable and Emerging Technologies for Smart Manufacturing (SETSM 2026) on April 15, 2026. The conference gathered a diverse community of international scholars, researchers, and industry experts, creating a vibrant academic environment for knowledge exchange and collaborative innovation.
