Did you know that even biodegradable poo bags still take decades to degrade and into tiny micro-plastics? These micro-plastics are also making their way to our oceans and harming our beloved marine life. Our more eco-friendly compostable poo bags, made from cornstarch, degrade completely within weeks, into natural elements which aren’t harmful to the environment. These bags are 20 μm (microns) thick so there is no danger of them splitting.
