Potato Plastic
A biodegradable material for one time use-products
Potato Plastic is a biodegradable material, made of potato starch. This means that it will decompose to nutrients for the soil in only two months when it ends up in the nature. Potato Plastic can be used for products such as cutleries, straws and saltbags. Potato Plastic is consisting of only potato starch and water. The technical part of this product is the production of the material. First, the exact amount of both ingredients are mixed together, and then heated until the fluid thickens. It is then poured into molds and exposed to heat until is a dry compact piece. Regarding of how much fluid is poured into a mold, the material can either become a thick, tough piece, or a thin film. This material is a kind of thermoplastic, which means that it can be molded under compression when it is exposed to heat and moisture. This opens up for many design possibilities, regarding everything from product selection to detailed patterns on the surface of the material.
