Our bags are produced from Cassava Starch which comes from the root of this plant.Our bags compost naturally in landfills within 3-6 months, are PLA free and do not leave any harmful traces in the soil. They also safely dissolve in water (although not in rain) leaving a totally natural liquid harmless to the environment.Our bags look like plastic, feel like plastic but contain zero plastic!! They are as durable as regular plastic and can carry up to 9 kilo’s in weight.
