According to the Ellen Macarthur Foundation, if current trends in single-use plastic continue, "there could be more plastic than fish (by weight) in the ocean by 2050." Having spent countless family vacations at the beach since she was a child, product design student Lucy Hughes, now 24, was distraught by the amount of single-use plastic she saw littering the shore and water. So she invented a bioplastic made from fish scales and skin collected at a fish processing plant. The scales and skin are bound together with red algae. For her product, called MarinaTex, Hughes just won a James Dyson Award recognizing ingenious design. From Smithsonian:
The resulting product is strong, flexible and translucent, with a feel similar to plastic sheeting. It biodegrades on its own in four to six weeks, which gives it a major sustainability advantage over traditional bioplastics, most of which require industrial composters to break down. In addition to utilizing materials that would otherwise be thrown away, the production process itself uses little energy, since it doesn't require hot temperatures. One single Atlantic cod fish produces enough waste for 1,400 MarinaTex bags.
