Under Construction

Work in progress

I've been teaching Circular Economy and Positive Impact exclusively for Erasmus University Rotterdam for 10 years. (And guided more than a hundred research projects.)

Now, to help other teachers, lecturers, students, journalists and (business) professionals, I have decided to share the knowledge and resources I've gained as an entrepreneur and academic since I started working on CE in 2008.

You are allowed to distribute, remix, adapt, and build upon my texts in any medium or format as long as you attribute it to me. So please mention my name, Diana den Held, and link to this website.
