This research study investigates the integration of green technologies, renewable energy sources, and the circular economy within the framework of Sustainable Industry 5.0 through a cross-case analysis methodology. The objective of this study is to examine how these elements can synergistically contribute to sustainable industrial practices, addressing critical challenges such as climate change and resource depletion. The rationale for this research stems from the urgent necessity to transition industries towards sustainable practices that not only enhance operational efficiency but also promote environmental stewardship and social equity. Despite extant literature highlighting the importance of these components, there remains a significant research gap regarding the long-term impacts of their implementation across diverse industrial contexts. This study employs a cross-case analysis methodology, focusing on organizations exemplifying advanced applications of Industry 5.0 principles, including Siemens, Tesla, Interface Inc, Tata Steel and BYD. The findings indicate that integrating green technologies and renewable energy can significantly reduce carbon footprints while optimizing resource utilization through circular economy practices. The implications of this research are substantial, offering insights for policymakers and industry leaders on effective strategies for fostering sustainable industrial transitions. Furthermore, the study underscores the importance of human-centered design principles in infrastructure development to ensure equitable benefits for all stakeholders involved. Future studies should focus on longitudinal assessments of these practices across various sectors and explore the interplay between digital technologies and sustainability initiatives.
