But they can only be washed for two months. Then they will disappear.

The other day, the James Dyson Award competition ended. Her former finalists created items such as, for example, a folding bike, a home fire extinguisher that can be connected to a faucet in the kitchen, or a universal lid that can close any container.

This year, a Swiss student Pontus Turnkvist and the same number of his university, Lund University, received 10 thousand pounds (13 thousand dollars) for developing material from potatoes. Its properties are similar to plastic, but it decomposes in less than two months. The student called this material Potato Plastic (potato plastic). The material is based on starch and water.

The student is confident that his invention is a great alternative to plastic items such as disposable tableware. The commission of the competition for a reason gave priority to the development of a Swiss student - every year the World Ocean is replenished with eight million tons of plastic.
