Abstract

A deicing formulation, comprising a chemically degraded extract derived from biowaste; and a salt is provided. Methods for preventing ice formation or removing ice from a surface by applying the deicing formula made of chemically degraded extract derived from biowaste and a salt to the surface are also provided.

Claims (19)

1. A deicing formulation, comprising:

a chemically degraded extract derived from biowaste has a molecular structure of C X H Y O Z P U N V , where the number of C atoms (X), H atoms (Y), O atoms (Z), P atoms (U), and N atoms (V) falls in the ranges of 4 to 42, 5 to 63, 2 to 15, 0 to 1, and 0 to 8, respectively; and

a salt.

2. The deicing formulation of claim 1 , wherein the biowaste is selected from the group of waste leaves of flowers; vegetation; vegetables; shrubs, pomace, rind or skin of fruits; and combinations thereof.

3. The deicing formulation of claim 1 , wherein the chemically degraded extract derived from biowaste is present in an amount from 0.5-16%, by weight.

4. The deicing formulation of claim 1 , wherein the salt is a chloride salt.

5. The deicing formulation of claim 1 , wherein the salt is NaCl, KCl, MgCl 2 , CaCl 2 , or any combination thereof.

6. The deicing formulation of claim 1 , wherein the chemically degraded extract is chemically degraded using a degradant selected from urea, NaOH, KOH, LiOH, bacteria, fungus, and combinations thereof.

7. The deicing formulation of claim 1 , wherein the deicing formulation is a liquid deicing formulation.

8. The deicing formulation of claim 7 , wherein the liquid deicing formulation comprises water or liquid waste from distillery industry.

9. The deicing formulation of claim 7 , wherein the liquid deicing formulation is configured to prewet a solid surface.

10. The deicing formulation of claim 9 , wherein the solid surface is selected from solid deicer, solid salt, traction abrasive, a transportation surface for vehicles, a transportation surface for pedestrians.

11. The deicing formulation of claim 7 , wherein the liquid deicing formulation is configured to perform an action selected from: preventing a bond of snow and ice; breaking a bond between compacted snow and ice with a solid surface; reducing the likelihood of snow being compacted into hard-to-remove conditions; reducing the bounce-and-scatter, and speed up the action of winter traction salt or sand; and combinations thereof.

12. A method of preventing ice formation or removing ice from a surface, comprising applying the deicing formulation of claim 1 to the surface.

13. The method of claim 12 , wherein the deicing formulation is applied in a liquid deicing formulation.

14. The method of claim 13 , wherein the liquid deicing formulation is configured to prewet the surface.

15. The method of claim 14 , wherein the surface is selected from solid deicer, solid salt, traction abrasive, a transportation surface for vehicles, and a transportation surface for pedestrians.

16. The method of claim 12 wherein the biowaste of the chemically degraded extract derived from biowaste is selected from the group of waste leaves of flowers; vegetation; vegetables; shrubs; pomace, rind or skin of fruits; and combinations thereof.

17. The method of claim 12 , wherein the salt is a chloride salt.
