Abstract: Biodegradable bags for disposing of a unwanted substance are formed from a bioplastic material made from a bio based material in the form of a maize flour, and a biodegradable plasticizer selected from the group consisting of vegetable oil, polyesters made from glycerin, glycerin, derivatives of glycerin, and combinations thereof. The maize flour comprises a minor volume percent of the total volume of the bioplastic material. A biodegradable additive is used to provide a degree of stiffness to the material, a preferred additive being polylactic acid. A UV stabilizer may optionally be included. Biodegradable bags have an open end and a closed end with a sidewall extending therebetween. The bag includes a feature for enclosing a substance once placed into the bag. In an example, the feature comprises an opening through a sidewall. Alternatively, the feature may include an adhesive section.
