## 5 Conclusions  
The present study aims to determine the key barriers to the implementation of CE in the textile sector. To achieve the study objectives, the authors conducted an extensive review of the literature. In addition, the application of FDM was performed to find the key barriers. After that, we analyzed the interrelationships amongst key CE barriers with the DEMATEL approach. CE concepts have been identified as an important research topic in today's environmentally conscious world. The textile companies are unable to implement CE in their supply chain due to high global competition, demand for sustainable production processes, and increasing environmental problems. As per the recent past, scholars have correlated CE implementations in the textile sector [29]. For textile companies, some studies stated that in the textile industry, CE practices are used as an eco-industrial design process [97]. In addition, while [PERSON] et al. [98] found that the CE refers to the transformation of business processes from the traditional linear \"take-make-dispose\" model to new waste removal and green waste elimination, few authors argue positively toward sustainability measures. Sustainability is positive to a CE, but CE implementation with sustainability measures are even better together instead of alone [99]. Nevertheless, CE implementation in the textile sector is not a simple task, as several challenges may exist during these initiatives, such as the fact that the textile sector depends on customer orders and raw material transportation costs. This indicates that there is a demand for favorable

Textile companies should concentrate on the reduction of communication and raw material transportation costs and final products. Therefore, the present research contributes to the existing literature in a selective manner. It determined the comprehensive list of 12 key barriers to the implementation of CE in the textile sector. In addition, it classifies the most significant barriers to cause and effect groups. In addition, it shows the degree of interaction of key CE implementation barriers with each other. This research aims to explore the DEMATEL approach applications in the analyzing of barriers to the adoption of CE actives in the textile sector. The DEMATEL model uses expert opinions to build a cause-and-effect diagram. Twelve barriers were identified based on a review of the literature and discussions with nine experts. The DEMATEL approach is used to explain the interrelationships with a causal relationship diagram and prominence (causal relationship graph). On this basis, the most significant barriers, the categories of the key barriers, and the group of causes and effects have all been identified. The twelve key barriers are divided into cause-and-effect groups. The aim of this study was to strengthen our understanding by determining the key barriers that could pose a critical adoption of CE in the textile sector. Among all the barriers, the most prominent barriers are B1, B3, and B4, as shown in Figure 3. However, from Figure 3, it is concluded that the barriers B1, B3, B4, B2, B6, and B7, out of which B1 has the highest impact value, cause these critical barriers. Similarly, B3 has the second-highest impact value. Therefore, it is suggested that B1 and B3 should be given due consideration. By comparison, \"lack of support supply and demand network (B4)\" is the least prominent or affected barrier based on the diagram of the causal interrelationships, as shown in Figure 3.  
The results of this study provide significant practical implications and theoretical implications, which will help the managers and policymakers of textile companies to implement a CE.
