Our pouches are made of biodegradable certified materials that can compost, including the ink and zipper. But, when we put them together to make a pouch, it creates a 'new product' and this needs a separate and expensive check in order to be certified, we need one for each single variation. Because of the high cost, we haven't done this. We tested it by burying our pouches in soil at home, and they broke down completely in 6 months. However, by filling the pouch with soil and seeds and then burying it we managed to accelerate the process by two fold.
