Bioplastic Sunglasses

Bioplastic is a plant-based compound that can be made out of any kind of starch.  The starch is combined with water, salt, and a plasticizer (glycerine) to create a material that is pliable yet structurally sound.  In the research leading up to this project, I made my own bioplastic out of corn, wheat, potato, and tapioca starch.  Corn starch had the most suitable properties, and after the addition of stone powder for greater rigidity, it was an ideal material for all kinds of products. 

These sunglasses were made using bioplastic.  The material has a beautiful rough texture reminiscent of concrete, but the sunglasses are light enough to be worn comfortably and smooth to the touch.
