Chitosan Bioplastic

February 18, 2018

Chitin-based biodegradable polymer

Scientists at Harvard University’s Wyss Institute for Biologically Inspired Engineering have developed a new biopolymer that mimics the toughness, durability, and flexibility of natural insect cuticle. A biological composite with a structure akin to plywood, insect cuticle consists of layers of the polysaccharide polymer chitin and protein. The Wyss researchers extracted chitosan sugar from discarded shrimp shells and engineered a thin, transparent film with a strength equivalent to aluminum at only half the weight. The new Chitosan Bioplastic is biocompatible, biodegradable, easily molded into complex shapes, and inexpensive because of the widespread availability of shrimp waste. Because of these beneficial characteristics, the material is a potential replacement for conventional petroleum-based plastic in applications ranging from consumer products to medical uses.

  1. Good Night,
    My name is Andrea, I´m an electrical engineer with a special interest about Chitosan Bioplastic. I´m now researching
    to carry out a project of manufacture and packaging of products based on biodegradable materials and produced with high efficiency machinery. I want to know if there is a way to buy this kind of materials for this purpose. I live in Colombia.

    I´ll be waiting for your kind response.

    Best Regards,

    • Dear Andrea, thank you for your comment. I do not stock material samples, so I encourage you to contact the Wyss Institute directly to obtain samples of this bioplastic. Best, Blaine

    • hey Andrea, i am an architecture student researching on the chitin as replacement for various architectural materials, can you help me out wit it,
      will be waiting for your reply,

  2. Would love to know more!
    Working on similar things.
    Andrea , will be in Colombia next year, would love to connect!

  3. Hello, Good day! We are high school students from the Philippines and our study is regarding bioplastic. Can we request a file or a paper of your study for the basis of our research? Do you also happen to know if chitosan can be used as a matrix in making bioplastic? Thank you and We are hoping for your response, God bless you.

  4. Myself Ankesh yadav ,student in madras university(msc zoology). Iam doing my project on chitosan based bioplastics, so sir can i get procedure for it?
