Potassium mixtures compositions and applications

A fertilizer or fertilizer additive composition for application to soil or fertilizer comprising distillate residue, bottoms material and/or waste potassium mixtures produced in natural fats and oils processing plants that produce biodiesel from low value high fatty acid feedstocks in a continuous process comprising one or more unit operations selected from reactive distillation, wiped-film evaporation, falling film evaporation, freeze crystallization, and glycerolysis, wherein the distillate residue, bottoms material and/or potassium mixtures comprise about 10% to about 60% ash, less than 1% moisture, and one or more of potassium acetate, potassium oleate and potassium superoxide, wherein said fertilizer composition comprises fertilizer and the by-product or waste potassium mixtures, and wherein the composition promotes microbial growth and activity, and wherein the microbes digest and degrade the composition.

A method of deicing or freeze conditioning a surface comprising applying to the surface a solid composition comprising distillate residue, bottoms material and/or waste potassium mixtures produced in natural fats and oils processing plants that produce biodiesel from low value high fatty acid feedstocks in a continuous process comprising one or more unit operations selected from reactive distillation, wiped-film evaporation, falling film evaporation, freeze crystallization, and glycerolysis, wherein the distillate residue, bottoms material and/or potassium mixtures comprise about 10% to about 60% ash, less than 1% moisture, and one or more of potassium acetate, potassium oleate and potassium superoxide.
