People throw away billions of plastic bottles every year and that’s a problem because it takes plastic around 450 years to decompose, which is kind of a long time. Ari Jónsson is a product design student who studies at the Icelandic Academy of Arts. Recently he came up with a way to create a completely biodegradable water bottle using red algae powder. The substance can be formed into a bottle by adding water, heat, placing the resulting jelly into a mold and then putting the mold into a freezer. “What makes this mix of algae and water an interesting solution is the lifespan of the bottle,” says Ari Jónsson, a product design student at Iceland Academy of the Arts, who created the experimental bottle. “It needs to contain liquid to keep its shape and as soon as it’s empty it will start to decompose.” Ari Jónsson exhibited his biodegradable bottle at a design festival in Reykjavik earlier this month.
