Abstract
Biodegradable pellet compositions comprising: a starch at about 30% to about 80% by weight of the composition, a plasticizer at about 2% to about 30% by weight of the composition; a flexibility agent at about 10% to about 40% by weight; a binder at about 3% to about 13% by weight of the composition; a hydrophobic agent at about 0.1% to about 5% by weight of the composition; and an emulsifier at about 0.1% to about 5% by weight of the composition. The compositions further comprise a defoaming agent where a biodegradable foam pellet is the end product. The compositions may optionally include a plant fiber.
