This research was applied in terms of purpose and developmental-exploratory in terms of approach and was conducted using a mixed qualitative–quantitative design. In the qualitative phase, 12 experts, including university professors, senior managers of manufacturing industries, and economic consultants, were selected through theoretical sampling until theoretical saturation was achieved. Data were collected using in-depth semi-structured interviews and analyzed through thematic analysis. In the quantitative phase, the statistical population consisted of senior managers of manufacturing industries in Tehran and Alborz provinces, among whom 338 participants were selected using simple random sampling based on the Krejcie and Morgan table. A researcher-made questionnaire with 21 items on a five-point Likert scale was used for data collection. Validity was confirmed through face validity, content validity, convergent validity, divergent validity, and CVR, while reliability was verified using Cronbach’s alpha. Data analysis was conducted using SPSS and SmartPLS software through descriptive statistics, confirmatory factor analysis, and structural equation modeling. The qualitative findings resulted in the extraction of 142 initial codes, which were reduced to 47 basic themes, 21 organizing themes, and 6 overarching themes. The final model included organizational factors, environmental factors, strategic factors for promoting the circular economy, realization of the circular economy, organizational consequences, and social consequences. Structural equation modeling demonstrated that organizational factors significantly influenced strategic factors for promoting the circular economy (β=0.299, t=3.40), and environmental factors also had a significant effect on strategic factors (β=0.471, t=6.053). Furthermore, strategic factors significantly affected the realization of the circular economy (β=0.683, t=13.296). The realization of the circular economy significantly influenced organizational consequences (β=0.677, t=13.047) and social consequences (β=0.460, t=5.884). All proposed hypotheses were confirmed. The findings indicate that promoting a circular economy in manufacturing industries requires simultaneous attention to organizational commitment, supportive environmental conditions, Islamic economic teachings, and strategic institutional cooperation. The proposed model demonstrates that integrating Islamic economic principles with circular economy strategies can improve sustainable resource utilization, reduce waste, enhance profitability and stakeholder satisfaction, create employment opportunities, and contribute to environmental preservation.</p> https://bmfopen.com/index.php/bmfopen/article/download/455/334
