SCOBY (also called biocellulose) is a product of sugars fermentation and forms a membrane on the surface of the liquid known as kombucha. During fermentation, the biocellulose forms by increasing in volume. This process is similar to the growth of onions, which grows through layering.
SCOBY is grown by the farmer not only for packaging production but also because of the nutritious by-product, which, due to its acidic PH and mineral compounds can be natural fertilizer, probiotic drink or even natural detergent. So maybe making packaging, like growing onions, not only will not litter the environment but even enrich it?
