Abstract: A biodegradable food container for holding and insulating food. The food container includes a wall structure constructed from heat-expanded grains bound together with a biodegradable bonding agent. In the preferred embodiment, the heat-expanded grains are popcorn and the bonding agent is a starch paste or other type of biodegradable bonding agent of food grade quality. The wall structure is formed by heating expandable grains to form the heat-expanded grains. The heat-expanded grains are then ground and mixed with the bonding agent to form a moldable popcorn mixture. The moldable popcorn mixture is molded to form a wall structure of a selected shape for holding and insulating food.
