Chitin is responsible for some of the most remarkable mechanical properties exhibited by natural materials, including nacre, insect cuticle, and crustacean shells. It is also the most abundant organic compound on earth after cellulose.

In 2013 we demonstrated how chitin can be used as platform to mimic complex natural composites (i.e. Insect cuticle). We were able to reproduce the synergy between hierarchical design and biomolecules, and the consequent extraordinary mechanical properties of natural composites. We called Shrilk to this “artificial natural composite”.

One year later we demonstrated how those principles can be introduced in manufacture, producing large three-dimensional chitin objects (cups, boxes, clips…) that are functional and sustainable. This achievement is consider one of the most promising results on sustainable manufacture.

Our results, even if using friendly materials, are obtained in a high tech environment, combining tools for manufacture, molecular analysis, and mechanical testing.


Recently, Reuben Hudson, Samuel Glaisher, Alexandra Bishop and Jeffrey L. Katz, have designed simplified version of our first results in the shape of a High/Middle school activity. As the authors describe their work:

It is a multiple day activity for students to create large-scale plastic objects made of chitin. The plastic objects created are durable and made from benign materials, making them suitable for students to take home to play with. Since the student-created plastic objects are sourced from biomass and fully compostable, the activity provides an opportunity to discuss depleting petrochemical resources and biorenewable feedstocks as well as issues of biodegradation vs persistence.


You can find the whole activity here:

From the Fermart lab we want to thank the authors for their work, and encourage teachers (and/or curious people) to try this at home/school.

    It would be nice to read it but I don’t have access to content. Is there any way to access? I’m very interested on reading it.
    Thank you.

      Dear Nabil, unfortunately I can’t make an article available here if I’m not its author. You can write to Reuben Hudson (rhhudson(-at-) or Jeffrey Katz (jlkatz(-at-) and ask them directly.

    Dear Javier, Thank you for your work and for the sharing. I’ve read the article and was thinking it would be a great activity or workshop for the Bio club members and SUTD students, to appreciate living processes while exploring possibilities of what could be made using chitin. Would it be possible for us to do so in SUTD? And would you be interested in conducting the activity?

    Our club is currently thinking to take on a direction towards biodesign, biofabrication and art:
