Investigation of barriers for circular economy using Delphi, Best Worst Method, and EDAS: An application study in Turkey for a manufacturing company

Adopting the principles of circular economy has become imperative for manufacturing firms to maintain their competitiveness in the global market. Examining the adoption of circular practices through the lens of companies' sustainability goals is essential for identifying specific objectives related to circular economy initiatives and overcoming associated barriers. This study presents a case analysis conducted within a manufacturing company to address these barriers. Initially, the company's sustainable development goals were assessed and weighted using the Best Worst method. Subsequently, barriers hindering the transition to a circular economy were identified through a comprehensive literature review, with critical barriers determined through the Delphi method. Leveraging the weighted sustainable development goals, a prioritized ranking of critical barriers was established using the EDAS method. The findings of the study underscore the significance of addressing key barriers to circular economy adoption. Notably, the top three barriers identified include the high cost of eco-friendly materials, the need for technological and infrastructural advancements, and stakeholder environmental awareness. This study holds practical importance in evaluating circular economy adoption barriers in alignment with sustainable development goals. Furthermore, it provides a practical application within a manufacturing company situated in Turkey, a developing country context.
