Concern for sustainable development and environmental protection has become increasingly important in the business world in recent decades. Looking for business professionals who are currently implementing sustainable development practices and the principles of the circular economy might be the most meaningful approach to the time and the space we are all heading towards in the future. This study seeks to identify the motivations, obstacles, strategies, and perspectives of specialists in the integration of the circular and sustainable economy model in businesses in the Romanian context. It focuses on providing a solid basis for promoting sustainable practices and policies in the business environment, considering theoretical elements and the perspectives and experiences of specialists. In our research, qualitative in-depth interviews were conducted among diverse specialists in Romanian businesses to gain insight. The research findings indicate consistent requests for consumer education and involvement in the circular economy process and for political support and funding sources for investments in assistive technologies. This article presents viewpoints from Romanian experts, entrepreneurs, and business decision-makers on the circular economy and sustainability. Decision-makers prioritize developing and promoting sustainable products and services, emphasizing the use of recycled materials, and using renewable energy for their activities. The presented results highlight the situation in Romania and implicitly make a significant contribution to the scientific knowledge in this field. Although the study’s qualitative nature limits its generalizability, it offers valuable insights and suggests potential directions for future research on aspects related to the circular economy and sustainability.
