  • Lignin-Urea Agricultural Fertilizer
    Publication number: 20220348514
    Abstract: Provided is a solvent borne fertilizer composition. The fertilizer composition includes a low molecular weight lignin in an amount of 5 or about 5 to 25 or about 25 weight percent solids, a carbohydrate in an amount of 1 or about 1 to 20 or about 20 weight percent solids, wherein the lignin and carbohydrate form a lignin-carbohydrate mixture; and a urea moiety bonded to the lignin-carbohydrate mixture.

  • Dust suppressant and soil stabilization composition comprising lignocellulosic byproducts
    Patent number: 11091697
    Abstract: Provided is a solvent borne dust suppressant or stabilization composition in a solvent which includes, a blend of an inorganic salt and a lignin-carbohydrate mixture, optionally with one or more of a surfactant and crosslinker, wherein the lignin-carbohydrate mixture may be a copolymer and may be present in an amount of 5 weight % to 50 weight % solids, wherein the lignin is a low average molecular weight lignin, the carbohydrate includes hemicellulose and wherein the lignin and hemicellulose are substantially derived from a non-wood source, a wood source or a blend thereof.
