The article "Designing the Business Models for Circular Economy—Towards the Conceptual Framework" by Mateusz Lewandowski explores the transition from a linear to a circular economy, emphasizing the need for comprehensive knowledge on designing circular business models. The study employs a literature review to identify and classify circular economy characteristics according to a business model structure. It identifies eight sub-domains of research on circular business models and redefines the components of the business model canvas in the context of the circular economy. Two new components—take-back systems and adoption factors—are identified, leading to the development of an extended framework for the circular business model canvas. The study also highlights the triple fit challenge as an enabler of the transition to a circular business model. The paper concludes with suggestions for further research and provides a conceptual framework to support practitioners in transitioning from linear to circular business models.The article "Designing the Business Models for Circular Economy—Towards the Conceptual Framework" by Mateusz Lewandowski explores the transition from a linear to a circular economy, emphasizing the need for comprehensive knowledge on designing circular business models.
