Types of Compostable and Biodegradable Plastic Bags

  • Cornstarch Bags: Almost half of the biodegradable poly bags use cornstarch incorporated into the plastic. The cornstarch component will begin to decay when exposed to a microbe rich environment. This breaks the plastic into tiny pieces.
  • Photo Sensitive Bags: These bags are designed to decay with prolonged exposure to the ultra violet rays in sunlight.
  • Oxo-Biodegradable Bags: These bags are among the most economical to manufacture and the most effective to use. They are completely biodegradable. This happens in a two-step process. First, the bag is oxidized by prolonged exposure to the oxygen in the air. After that, the oxidized fragments convert into carbon dioxide, a harmless biomass and water.
  • Bags Using Aliphatic Technology: Somewhat similar to using starch to encourage nature to deconstruct poly bags, Ailphatic poly bags also rely on microbes to breakdown the bag into its constituent molecules.
