US Patent 7972531 Anti-freezing/deicing agent and related methods

A composition for deicing or inhibiting formation of ice includes waste material from a fermentation process for producing an amino acid from a carbohydrate source, and at least some second anti-freezing and deicing agent or a carrier. The active agent is waste material from a fermentation process for producing an amino acid from a carbohydrate source. The carrier may be water. A method for deicing an icy surface includes applying to that surface an effective amount of waste material from a fermentation process for producing an amino acid from a carbohydrate source.
