Tayst’s BPI compostable pods completely break down after use with proper disposal and give back fertile nutrients to the soil as it naturally decomposes. All the parts of the pod are made from the Earth – the lid is created from biological materials and water-based compostable ink, the ring is made from compressed corn starch combined with bio resins, and even the unique mesh filter is designed with renewable bio resins. No plastic, no harmful materials, no fuss. Only great coffee that’s great for the ecosystem.
