The words compostable and biodegradable are quite often confused but there is quite a difference between the meaning of both words.
Everything is biodegradable - over time. Even a plastic bottle will biodegrade over centuries. Biodegrade simply means to break down into smaller pieces. The problem with that is that the smaller pieces are still plastic.
Not everything is compostable. Compostable means that a product is capable of disintegrating into natural elements in a compost environment, leaving no toxicity in the soil. This typically must occur in about 90 days.
Caffesso Eco Blends are 100% compostable - the capsule is made from sugar beet and sugar cane so can legitimately be called compostable. We are launching, by 7th November 2018, Caffesso Eco Blends so keep an eye out.
