Abstract
The present invention relates to a novel deicing/anti-icing composition. The composition is formed by alkalinically degrading reducing sugars. The reducing sugars are preferably found in an industrial waste stream, such as corn steep water. The composition is inexpensive, biodegradeable, and nontoxic to the environment.
Claims38
A deicing composition comprising:
- alkaline degradation products of reducing sugars;
- said deicing composition not including a chloride salt.
A method of making a deicing composition comprising:
- alkalinically degrading reducing sugars to form a deicing composition that does not include a chloride salt.
A method of using a deicing composition formed by alkalinically degrading reducing sugars that does not include a chloride salt, comprising:
- applying the composition to a surface prior to accumulation of snow and ice on the surface or upon which snow and ice is already present.
A method of making a deicing composition comprising:
- alkalinically degrading reducing sugars to form a deicing composition;
- and separating precipitated proteins from the alkalinically degraded reducing sugars.
A method of making a deicing composition comprising:
- alkalinically degrading reducing sugars to form a deicing composition, wherein the reducing sugars are from an agribusiness waste stream;
- and enzymatically digesting proteins in the waste stream prior to alkalinic degradation.
A deicing composition comprising:
- alkaline degradation products of reducing sugars from an agribusiness waste stream.
A deicing composition comprising:
- alkaline degradation products of reducing sugars, said composition including enzymatically degraded proteins.
