Abstract: A dust suppression composition includes a combination of a crusting agent, a dust suppression agent and a carrier. A method of suppressing dust of an aggregate material includes the step of contacting aggregate material with an effective amount of that dust suppression composition.

Abstract: 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.
