The shift from linear to circular supply chains (CSC) has emerged as a crucial strategy for addressing environmental sustainability challenges. A circular supply chain emphasizes reducing waste, reusing resources, and recycling materials to create a closed-loop system that minimizes environmental impact and conserves resources. Despite its potential benefits, many organizations face significant barriers when adopting CSC practices. These barriers can be classified into internal and external challenges. Internal barriers include lack of expertise, insufficient awareness, resistance to change, financial constraints, and inadequate stakeholder engagement. On the other hand, external barriers stem from governmental regulations, market dynamics, supply chain complexity, and limited collaboration opportunities. Overcoming these obstacles requires a comprehensive approach that includes engaging top management, fostering a culture of innovation, securing financial resources, and establishing effective partnerships with stakeholders. Furthermore, integrating circular design principles and addressing consumer perceptions about the value and quality of circular products are essential steps in making CSC practices more viable. Organizations must also navigate regulatory frameworks and collaborate with external technical support to overcome challenges related to policy, infrastructure, and technological capacity. By addressing these multifaceted barriers, companies can transition successfully to circular supply chains, positioning themselves as leaders in sustainability while benefiting from long-term economic gains.
