For the assignment all the businesses in Trondheim that are busy with sustainability / circular economy were mapped. A user friendly physical map of the city will contain relevant information about these businesses and what they have to offer. To make sure that enough correct information was gathered, I went around town to speak to these businesses about for example the (business)models they use, what their views are and what they offer. Next to this, literature research was done to support this. For the University of Twente, wrote a report to describe the process of the assignment and the research done.
