NOVELTY - Producing a fertilizer composition from still bottoms obtained from milling of a starch-containing feedstock, comprises: (a) providing or receiving solids-rich still bottoms obtained from a distillation unit configured for purifying a fermentation product derived from glucose; (b) separating the still bottoms into a still bottoms solids stream and a thin stillage stream; (c) removing a portion of the water in the thin stillage stream to generate condensed distillers solubles stream; and (d) recovering at least a portion of the condensed distillers solubles stream as a fertilizer composition.    USE - The process is useful for producing a fertilizer composition and a dry or wet distillers grains product from still bottoms obtained from milling of a starch-containing feedstock including corn (preferred), wheat, cassava, rice, potato, millet and/or Sorghum (claimed), where the fertilizer composition is useful for growing corn. No biological data given.    ADVANTAGE - The process is capable of economically producing the fertilizer composition with less energy consumption and without greenhouse-gas emissions thus improving yield of the corn.    DETAILED DESCRIPTION - Producing a fertilizer composition from still bottoms obtained from milling of a starch-containing feedstock, comprises: (a) providing or receiving solids-rich still bottoms obtained from a distillation unit configured for purifying a fermentation product derived from glucose obtained from the milling; (b) separating the still bottoms into a still bottoms solids stream and a thin stillage stream; (c) removing a portion of the water contained in the thin stillage stream for generating a condensed distillers solubles stream; and (d) recovering at least a portion of the condensed distillers solubles stream as a fertilizer composition. An INDEPENDENT CLAIM is included for a process for producing a distillers grains product from still bottoms obtained from milling of a starch-containing feedstock, comprising the steps (a)-(d) as above per se, and dewatering and/or drying at least a portion of the still bottoms solids stream to produce a distillers grains product.
