While plastic waste is piling up in landfills, Iceland may have found a solution to this problem! An Icelandic student, Ari Jónsson, invented a biodegradable water bottle that contains red algae powder. Such bottles remain in their shape as long as they have water inside, but they begin to decompose as soon as they’re empty. The inventor assures that the water from such a bottle is made of 100% natural materials and is completely safe to drink. Let’s see if this invention becomes widely-used in the future.
