These swing bin liners are completely degradable! 
 
An additive of salts called d2w is added to petroleum based plastic at the extrusion stage, which makes it degradable - it accelerates the natural process of oxidation until the product is no longer a plastic. This can then be used as a food source by bacteria and fungi on land or sea. Amazingly, it will not leave any fragments, methane, harmful residues, or any trace of toxic residues or microplastics.
