My self-biodegradable plastic made from shrimp shellsUpdate: 7/14/2015
According to the researchers, the objects made from bioplastics have characteristics similar to those objects made of synthetic resin, but does not affect the environment.
Instead of using plant materials such as cellulose plastics, bioplastics research group at Harvard University is derived from chitin, a natural polymer bearing, one of the abundant organic material on earth.
Most sources of chitin in the world today are extracted from shrimp shells are usually discarded. But so far, the materials engineer has not been able to produce objects in three dimensions (3D) complex material made from chitin.
Group Wyss Institute researchers, led by Dr Javier Fernandez leader and director Don Ingber has developed a new method to handle chitin can then use this material to manufacture large items, with 3D complex shapes, using the techniques of traditional plastic molding.
When he was discharged, bioplastics will biodegradable chitosan within 2 weeks and will produce nutritious substances help plants grow.
