Plant-based compositions and uses thereof

摘要

The present invention relates to compositions comprising a plant material and methods for using the same. The methods include extracting or removing a substance from a substrate, or remediating a substrate from a substance. The substance can comprise a hydrocarbon-containing substance, a protein, lipid, wax, fatty acid or fatty alcohol, or a combination thereof.

主权项

1. A method for extracting a hydrocarbon-containing substance from a substrate, comprising contacting the substrate with an aqueous composition under conditions effective for extracting at least some of the hydrocarbon-containing substance from the substrate, wherein the aqueous composition comprises:
a mixture obtained by (a) allowing water, plant material and an inorganic base to (i) stir at about 10 ° C. to about 100 ° C. for about 2 hours to about 4 hours or (ii) stand at about 10 ° C. to about 100 ° C. for about 10 minutes to about 8 hours, and (b) removing undissolved solids from the mixture; 0% to about 10 wt % of an alcohol; about 0.5 wt % to about 15 wt % of a base; 0% to about 10 wt % of a salt; 0% to about 10 wt % of an acid; 0% to about 10 wt % of an additive; and about 10 wt % to about 95 wt % of water; wherein the aqueous composition has a pH of about 13; the amount of plant material is about 1 wt % to about 50 wt % of the aqueous composition; and the plant material is hemp seed, soybean, or combinations thereof.
