Abstract
The rapid depletion of natural resources, increasing waste generation, and escalating environmental impacts of conventional manufacturing systems have intensified the global shift toward sustainable industrial practices. Green manufacturing technologies play a pivotal role in enabling this transition by integrating resource efficiency, cleaner production, and closed-loop material flows aligned with circular economy principles. This paper examines the technological foundations and strategic significance of green manufacturing in fostering circularity across industrial value chains. Key approaches discussed include energy-efficient processes, sustainable material selection, eco-design, additive manufacturing, waste minimization, remanufacturing, and advanced recycling technologies. The study further highlights the role of digital tools such as Industry 4.0, life cycle assessment, and smart monitoring systems in optimizing resource utilization and reducing environmental footprints. By evaluating environmental, economic, and operational benefits, the paper demonstrates how green manufacturing technologies contribute to reduced emissions, enhanced material recovery, and long-term industrial resilience. Challenges related to technological integration, cost, scalability, and policy implementation are also addressed. The findings emphasize that the adoption of green manufacturing technologies is not only an environmental imperative but also a strategic pathway for industries to achieve sustainable growth and competitiveness within a circular economy framework.
Keywords: 6R Framework, smart manufacturing, circular economy, industrial ecology and life cycle assessment.
