The sustainability of supply chains has become one of the most important global issues depending on the UN 2030 vision. Considering that an estimated 80% of global trade is realised through supply chains, it will be sufficient for businesses to transform their supply chains into a more sustainable structure to impact the world positively. From this point of view, the way to achieve sustainability is through the trade perspectives of buyers and suppliers in global supply chains and value networks. Supply chains mainly include an upstream linear material flow where materials transform from raw material form to the final product and reach the end user. Still, they also include limited downstream product flows. On the other hand, the circular economy (CE) promises a business ecosystem where innovative business models are developed to ensure the efficient use of waste materials and to extend and redesign the useful life of products. From the point of view of supply chain professionals, prioritising suppliers that provide regenerated material in sourcing inputs required for manufacturing can be a key to the transition from a linear supply chain to a circular value chain. Undoubtedly, both ensuring the sustainability of operations and implementing the circular value chain approach require all businesses’ participation. Besides, the circular approach will require radical changes in the general linear supply chain processes “plan-source-make-deliver and return”. Return processes express the place of circular strategies in supply chain orthodoxy. In general, return operations are handled at the dyadic level, where a buyer and a seller usually handle the recycling, repair or remanufacturing of products. In this study, a research methodology approach that encompasses two phases was adopted. In the first phase, businesses with a circularity-oriented business model were subjected to an in-depth case study analysis. In the second phase, exploratory research was conducted on the supply chain managers of manufacturing companies operating in Turkey with an in-depth interview technique. The research aims to explore the circular strategies of manufacturing companies with a traditional linear supply chain structure. However, determining the perceptions of supply chain professionals regarding the concept of circular value chains is another aim of the research.
