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.

5.3.3 Textile to textile recycling

Course subject(s) Module 5. Waste = Food

Alternatives to the crude down-cycling process exist. Gwen describes two types of technologies that allow us to reach high-quality (virgin or near-virgin) fibers: mechanical recycling and chemical recycling. While watching this video, ask yourself whether chemical recycling is an example of the technical cycle or the biological cycle of the Butterfly Diagram.

MAIN TAKEAWAYS

  • Mechanical recycling is a physical process of shredding textiles and turning them into new yarns (for instance through carding, combing and spinning). There can be some loss of quality, as shredding may damage the length of the fibers. 
  • Chemical recycling entails breaking the fiber down to its basic chemical components, removing the impurities and bringing the fiber back to virgin quality.
