Important announcement

Dear visitor,

Please note that this OpenCourseWare platform will be replaced at the end of 2026 by a new platform (under the same url ocw.tudelft.nl).

Courses and their contents that are currently available the platform will partly be migrated. URL’s for this content will change and content might be unavailable for some time. In addition, some courses will not be available anymore.

If you are linking to specific courses on this platform (for instance for your students), please take timely measures to avoid problems with access. Possible actions are:

  • Download the materials to your local platform (laptop, server)
  • For educators only (including TU Delft lecturers): Contact us at ocw@tudelft.nl and inform us what course you are using in what context (institute, program, period of use, number of students). We will research (in collaboration with the authors of the course) and decide if we will migrate the course, and if yes, can supply you with a new url.

Thank you.

1.1.3 What are the Circular Design Strategies?

Course subject(s) Module 1 Design for Recycling at a Systems Level

Earlier, we discussed the two cycles that together form the circular economy. In the schematic representation (also called ‘the butterfly diagram’) shown below, we can see that recycling is only one of several restorative activities that take place within the technical cycle. The inner loops in this diagram represent other activities for value retention, such as maintenance and repair, reuse, refurbishment, and re-manufacturing.
