Shrilk Biodegradable Plastic
Wyss Institute researchers have developed a fully degradable bioplastic by isolating a material called chitosan found in shrimp shells and forming a laminate with silk fibroin protein that mimics the microarchitecture of natural insect cuticle. The new material, called “Shrilk”, can be used to manufacture objects without the environmental threat posed by conventional synthetic plastics,...
Video/AnimationEnvironmental Impact: Chitin-Inhibiting Pesticides Called into QuestionChitin, a molecule that serves a purpose in the developmental biology of insects, fungi and shrimp, has long been a target of growth-inhibiting pesticides due to the belief that it did not exist in vertebrates. For decades, chitin-inhibiting pesticides have stunted the growth of insects and fungi to protect valuable crops. Now, research from the...
Audio/PodcastShrimp Shells Could Make the Green Plastic of the FutureUnlike other forms of bioplastic, like those made from potatoes or corn, chitin plastic does not simply replace the carbon source for the polymer, it actually replaces the carbon-based plastic polymer, making it a totally biodegradable and sustainable material. Researchers at Harvard’s Wyss Institute used chitin from discarded shrimp shells from a shrimp processing plant...
Video/AnimationChitosan BioplasticIn this video, the team grew a California Blackeye pea plant in soil enriched with its chitosan bioplastic over a three-week period – demonstrating the material’s potential to encourage plant growth once it is returned to the environment.
