It’s an edible juice bottle, says Dezeen. The creation, from Swedish design studio Tomorrow Machine, is made from a “potato starch-based material” coated in a “bio-based, water-resistant barrier” on both sides. Once its contents are drunk, the bottle can be peeled like fruit rind. The material then begins to decompose, and can be eaten or dissolved in water…
The Knowledge
It’s made from potato starch, so I can’t see it harming the environment.
I put potato peelings on the compost heap, so they go back onto the garden when they have broken down.
The potato starch this bottle is made from dissolves in water in just 20 minutes, though. The potatoes must go through a process to obtain just the starch, so not sure what the carbon footprint of that process would be.
I found a website of the company that has made this bottle and has been experimenting with other types of bio-degradable packaging made from extruded starch.
