Product-service systems (PSS) are one of the business models that can promote circular economy and sustainability; however, to design this kind of solution, holistic approaches must be used, integrating different areas of knowledge. Thus, this study proposes a conceptual solution based on the PSS business model to the problem of reverse logistics of coffee capsules, through the application of the Requirements Engineering method for Sustainable PSS design, with a focus on the initial phase. With an emphasis on the business model and value proposition, a conceptual solution was developed to promote the circularity of the capsule chain based on the analysis of the main stakeholders' needs. The value proposition of the PSS solution for the issue of coffee capsules was described as the “cocreation of sustainable value to stakeholders to foster the circularity of the chain”, considering consumer involvement through education and rewards in product disposal processes. The results reinforce the need to integrate critical stakeholders to add the desired value in creating a sustainable PSS solution and the need to pivot the business model during the solution development process.
