Polish designer Roza Janusz has found a way to create fully edible, fully biodegradable food packaging out of a bacteria fermentation process. To produce the material, she starts with a kombucha SCOBY (aka symbiotic culture of bacteria and yeast) which she then feeds with other organic substances and lets it grow for two weeks.

When it comes to edible packaging, Poland is showing the way to the rest of the world. Biotrem's edible tableware made from wheat bran is a second example that has already hit the market.
