Sustainability: 

Corn starch is made from corn, which is sustainable, renewable and easy to produce. It doesn't contain harmful chemicals or toxins that are commonly found in conventional plastics. Cornstarch plastic products look and feel just like regular plastic, but they are 100% biodegradable and compostable.
