Plastic bottles can lay around in landfills or the ocean for centuries and have been a major issue in the world. An Icelandic product design student was inspired to create a little something to address the issue.
Ari Jónsson, is from the Iceland Academy of the Arts and he has harnessed the properties of red algae to create a biodegradable bottle for drinking water. The bottles are made out of agar powder, which derives from the supporting structure in the cell walls of certain species of algae. When the agar powder is added to water and allowed to cool, it sets and molds into a jelly-like substance.
The bottle retains its shape when it's full of fluid but starts to decompose as soon as it's empty it. Since it's made of all natural and non-toxic materials, Ari says "you can even eat the bottle – although agar is used as a laxative, so you might want to go easy on it."
This could be an interesting concept that can help solve the ever growing plastic problem although its fairly new and more research will need to be done on the subject. After looking at the bottle I don't think this idea could be very popular as it makes it look like one is drinking dirty water.
