This toolkit offers a starting point and a framework for uncovering circular potentials and barriers and to potentially identify new circular business models. The tools in this toolkit focus specifically on mapping a company's circular potentials in the value chain it operates within. And it gives priority to understanding, framing and re-fining the value businesses create in the value chain, exploring the interaction with both customers, collaborators and influential stakeholders. The toolkit includes a Circular Business Model Map, a guide on how to use it, as well as video guidance on how to use the method.
