Banana Plastic
Elif Bilgin, an inventor from Turkey, devised a way to make plastic from banana peel when she was 16. She was inspired by seeing all the plastic waste in the Bosphoros strait in Istanbul, and wanted to make bioplastics which could replace the ever-present petroleum-based plastics in the world.
Her method is beautifully simple, using a couple of cheap chemicals and household appliances, it’s easy enough for anyone to make. The banana plastic was entered into Google Science Fair 2013, and you can read all about her method here.
