This study fills a significant research gap by examining the factors influencing the circular economy in Thailand, particularly within the context of developing countries. Utilizing regression and correlation analysis, we investigate key environmental and socioeconomic variables: greenhouse gas emissions, forest area percentage, income levels among the poorest 20% of the population, access to electricity, and income inequality. The novelty of this work lies in its comprehensive integration of these dimensions to identify barriers and sustainable circular economy. Key findings reveal that higher greenhouse gas emissions correlate with increased recycling, underscoring the need for stricter emission controls and cleaner technologies. Conversely, greater forest coverage is associated with reduced recycled waste, highlighting the importance of forest conservation and sustainable land use. Economic disparities significantly impact recycling efforts, necessitating supportive policies for lower-income groups. Increased access to electricity correlates with higher waste generation, emphasizing the need for sustainable consumption practices. Although income inequality correlates with recycling rates, it is not a significant predictor, indicating the necessity for broader economic and environmental policies. This study offers novel, comprehensive recommendations for advancing Thailand’s circular economy. Strategies include implementing emission controls, enhancing forest conservation, promoting economic empowerment, encouraging sustainable consumption, and developing integrated policies. These recommendations aim to address identified challenges and support sustainable growth in alignment with circular economy goals.
