IDEO Circular Design Kit
This toolbox contains 28 step-by-step methods, 3 mindsets with videos, 4 stories, and lots of resources (workshops, worksheets, videos, links, case studies).
It has been created for people who want to work more with circular design and provides all of the inspiration and practical support you'll need to start. The methods are divided into 4 categories: understand, define, make, release. They draw on the fields of design, business strategy, and sustainable development.
It was developed by IDEO.org and the Ellen MacArthur Foundation in 2017.
