This article explores how digital technologies enable circular economy practices, where resources are reused and recycled rather than discarded, creating sustainable business models.

• Circular economy decouples growth from resource consumption through reuse, recycling, and regeneration
• HPC enables rapid simulation and material design for sustainable product development
• AI/ML optimizes resource use, predicts demand, and automates sorting of recycled materials
• Big data analytics measures circularity KPIs like resource efficiency and waste reduction
• IoT sensors track material flows and supply chain movements in real-time
• Blockchain creates transparent, traceable supply chains and secondary markets for used products
• Additive manufacturing reduces waste through on-demand, customized production
• AWS Global Impact Computing Team supports circular economy transformation initiatives

Digital technologies combined with AWS services enable businesses to build closed-loop systems that maximize resource utilization, minimize waste, and achieve long-term sustainability benefits.
