Bio-derived composition for dust control
Bio-derived glycerides formed from a reaction between waste glycerol and biodegradable or bio-derived fatty acid esters such as crude biodiesel or soybean oil triglycerides are useful as dust suppressants.
1. A composition comprising a biomaterial comprising a mixture of bio-derived glycerides, wherein the composition is formulated for use as a dust control agent.
2. The composition of claim 1 , wherein the bio-derived glycerides comprise at least two glycerides glyceride selected from the group consisting of a monoglyceride, a diglyceride, and a triglyceride.
3. The composition of claim 2 further comprising glycerol, and wherein the bio-derived glycerides comprise at least one monoglyceride, at least one diglyceride, and at least one triglyceride.
4. The composition of claim 3 , wherein the biomaterial comprises heterogeneous bio-derived glycerides.
5. The composition of claim 1 , wherein the bio-derived glyceride is produced from a reaction between glycerol and a biodegradable or bio-derived fatty acid ester.
6. The composition of claim 5 , wherein the glycerol is obtained from an organic waste stream.
7. The composition of claim 5 , wherein the biodegradable or bio-derived fatty acid ester comprises a plant oil, an animal fat, or a fatty acid methyl ester (FAME).
8. The composition of claim 7 , wherein the plant oil comprises soybean oil.
9. The composition of claim 7 , wherein the fatty acid methyl ester comprises biodiesel.
10. The composition of claim 1 , further comprising at least one additive selected from the group consisting of a dust control agent, a cross-linking agent, a drying agent, a hygroscopic agent, a stabilizing agent, and a defoaming agent.
11. A method for making a dust control agent, the method comprising reacting glycerol and a biodegradable or bio-derived fatty acid ester under conditions to produce a biomaterial comprising at least one monoglyceride, at least one diglyceride, and at least one triglyceride, and formulating the biomaterial into a dust control agent.
12. The method of claim 11 , wherein the glycerol comprises crude glycerol from an organic waste stream.
13. The method of claim 11 , wherein the biodegradable or bio-derived fatty acid ester comprises at least one of soybean oil or biodiesel.
14. The method of claim 13 wherein the biodiesel is crude biodiesel.
15. A method for controlling dust on a road or soil surface comprising applying the composition of claim 1 to the road or soil surface.
16. The method of claim 15 , wherein the composition further comprises at least one additive selected from the group consisting of a dust control agent, a cross-linking agent, a drying agent, a hygroscopic agent, a stabilizing agent, and a defoaming agent.
17. The method of claim 15 , wherein the composition comprises an aqueous composition, and wherein the biomaterial is dissolved, suspended or emulsified in the aqueous composition.
18. The method of claim 15 , further comprising applying a cross-linking agent or drying agent to the road surface after application of the biomaterial.
19. A road construction material comprising gravel and the composition of claim 1 .
20. A road surface or roadbed comprising the composition of claim 1 .
