Bioplastics are plastics which are created from plant material.

Biodegradable plastics can be broken down by microorganisms and eventually fully decompose into water and carbon dioxide, making them friendly to people and the environment.

Japan Cornstarch has succeeded in developing a biodegradable bioplastic made primarily from cornstarch, marketed under the brand name "Cornpole".

Cornpole is used for a wide range of applications, for example a material for ballpoint pens, agricultural mulching films, and paints.
