Let's help save the oceans and our planet! These straws are manufactured using sugarcane bagasse and Oxo-biodegradable catalytic additives without affecting the clear straw's physical characteristics. Making these straws 100% biodegradable and environmentally friendly. 100% Oil Free and Non-Eco-Toxic, Food Safe. Once our eco straw is exposed to oxygen, water, and light (sun), and is consumed by microorganisms the biodegrading process starts and this straw will turn into biomass, co2, and water. Fully degrades within 6 to 36 months depending on environmental conditions. Natural breakdown typically takes 95 days. 100% agricultural waste recyclable, nontoxic, and made from a Sugarcane Residue Bagasse.
