In both EcoDesign Circle and EcoDesign Circle 4.0, methods and tools for creating circular business models were developed, starting from the design stage. Among the tools is EcoDesign Learning Factory, a workshop which illustrates the whole potential of circular design. EcoDesign Audit charts the present situation of a company and its prospects in circular economy and design. EcoDesign Sprint, developed by Design Forum Finland, aids companies in designing products and services in accordance with the circular economy. Essential in all the methods is collaboration in multidisciplinary teams and making use of design methods.
