Researchers at Harvard's Wyss Institute have developed a method to carry out large-scale manufacturing of everyday objects -- from cell phones to food containers and toys -- using a fully degradable bioplastic isolated from shrimp shells. The objects exhibit many of the same properties as those created with synthetic plastics, but without the environmental threat. It also trumps most bioplastics on the market today in posing absolutely no threat to trees or competition with the food supply. The advance was reported online last week in Macromolecular Materials & Engineering.
