Scientists have engineered a new form of plastic which is composed of chitin derived mainly from discarded shrimp shells. Although the material is not waterproof and must be coated in a thin layer of wax in order to be so, it is completely biodegradable when exposed to the right conditions. In addition to degrading more than current “green” bioplastics, there are no harmful byproducts when the material is produced. If the process could be scaled, this new plastic could help fill a need for new sustainable materials.

By the way, in this article there is an interesting video showing a plant growing in chitosan-based soil.
