Reverse supply chains take a variety of forms, depending on the nature of the product, the business model, the stakeholders and other factors. This article will contribute to a better understanding of how different types of reverse supply chains function, how they can be modelled and their performance assessed. The research is based on a semi-structured approach using case studies, interviews and qualitative analysis. A generic RSC model is suggested in conjunction with an analysis of circumstances and factors of influence, with the intention to trigger further investigation. A better understanding of RSC may lead to more companies engaging in returning products and materials to the process of usefulness suggested by the circular economy concept, hence leading to a more sustainable way of running manufacturing businesses.
