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.

Home Teachers Ruud Balkenende

Prof.dr. A.R. Balkenende

Ruud Balkenende is professor of Circular Product Design at the faculty of Industrial Design Engineering at TU Delft. He received his PhD on a doctoral thesis about the use of copper as an automotive exhaust catalyst material. In 1990 he joined Philips Research, where he has been active at the interface of technological innovation and business applications.

Since 2009 he has been mainly involved in research and development related to materials scarcity and product recyclability. Linking product architecture and materials science to resource efficiency was the main driver. Since 2013 his activities extended from recyclability to circular economy, i.e. reusing products or parts at a functional level instead of recovering materials.
