The all-natural container is biodegradable.
…..To create the form of the bottle, Jónsson combined the water and the agar, heated the mixture, poured it into a mold, and cooled it down quickly. The H2O binds and thickens the agar when it cools down, so it keeps the shape of the water bottle, explained Jónsson.
The real magic happens when the bottle is emptied. “It becomes rotten…. It will go bad like other foods,” said Jónsson.
When the bottle is left sitting in open air, it takes about a week for it to shrink down. It can sustainably decompose in soil, but Jónsson has not yet determined how long that process would take. A plastic water bottle, on the other hand, takes more than 1,000 years to biodegrade, and in the U.S. more than 2 million tons of the containers are wasting away in landfills…..
