Young Inventor Creates Plastic from Fish Scales

Lucy Hughes, a 24-year-old English inventor, has used fish skin and scales(鳞）to create a new kind of plastic that will break down in about six weeks. Her invention won 2019 James Dyson Award, which was created by the famous English inventor James Dyson to encourage students to try to use their creativity to solve problems in the real world.

Lucy Hughes studied how to design products at the University of Sussex in England. As a designer, she knew a lot about how wasteful many products are. Plastic bags, for example, are often used once for a short time and then thrown away. She decided to challenge herself to make something out of waste instead

The University of Sussex isn't far from the coast. Ms. Hughes spent some time studying the fishing business and the waste from fish that were thrown away. After some tests, she decided that the fish skin and scales seemed like the most likely parts for her product. She tried more than 100 different experiments before getting things just right. Ms. Hughes called her finished product "MarinaTex". It solves two problems:  the single-use plastic and fish waste.

MarinaTex is clear and feels like plastic, but it's stronger than normal plastic that is of the same thickness. It is also cheap to make since it's made from fish waste.  The process of making MarinaTex also doesn't use much energy. Most importantly, MarinaTex doesn't take hundreds of years to break down. On its own, it breaks down in four to six weeks.

For winning the contest, Ms. Hughes will earn f,30, 000. Her school will get f,5, 000. She is looking forward to moving ahead with her idea. She hopes the award money will help her with the process of getting MarinaTex into use as quickly as possible. She thinks that one of the best uses for MarinaTex will be in some kinds of food packaging.
