Compositions comprising asphalt and corn oil are provided, as are the shingles made using the compositions, methods for making the compositions, and methods for making the shingles. The compositions comprise mixtures of asphalt and corn oil, and the mixtures are oxidized to attain desirable properties.

Methods and systems for isolating a high purity starch stream are provided. The methods provide an initial treatment step in advance of traditional grinding or fractionation operations (such as dry milling or wet milling operations) that facilitate separation of starch from other components of starch-based grains, for example facilitate separation of soft endosperm from other components of corn kernels including hard endosperm. The systems include a first treatment system for separating a high purity starch stream from other components of the grain stream, wherein the system can be configured as a bolt on for traditional milling operations such as wet milling and dry milling operations.

Methods and systems for washing grain particle material and/or a stillage composition. Washing can be used to separate components such as one or more mycotoxins from the grain particle material and/or stillage composition. The methods include providing an aqueous composition that includes grain particle material or a stillage composition, and an aqueous liquid. The aqueous composition is separated into a solids fraction and at least one liquid fraction so that at least a portion of the components are separated from the solids fraction into the liquid fraction.

Provided herein are compositions, methods, systems associated with propagation and fermentation, and co-products of biochemical production processes, for example, a DCO co-product resulting from converting oil containing grains into bio chemicals via fermentation in the presence of endogenous esterase. The DCO resulting from the processes exhibits lower metal ion content relative to a DCO obtained in the absence of endogenous fermentation with an esterase such as a lipase. The DCO is useful as a feedstock for the production of renewable diesel.

Systems and methods for fractionating whole stillage from an ethanol production facility are provided. Whole stillage undergoes a separation of its liquid portion (thin stillage) from the solid portion (fiber cake). In some embodiments, the solids and liquids in whole stillage may be separated utilizing a screening centrifuge. The fiber cake may be dried to generate a high fiber animal feed. The thin stillage may be provided to a three phase separator for separation into an oil emulsion, an aqueous clarified stillage, and a protein paste. The protein paste may be dried to generate a high protein animal feed with greater than about 45% protein content. The clarified thin stillage is condensed to yield a syrup with greater than around 60% solids. The oil emulsion is subjected to a pH adjustment to liberate the oil from the emulsion, which is then separated.

The present disclosure relates methods and systems for refining grain oil compositions using water, and related compositions produced therefrom. The present disclosure also relates to methods of using said compositions. The present disclosure also relates to methods of using grain oil derived from a fermentation product in an anti-foam composition. The present disclosure further relates to stabilized emulsion products and methods for forming thereof.

The present invention relates to using high oil corn to make a biochemical such as ethanol. More particularly, the invention relates to methods of making a biochemical using relatively low temperature saccharification followed by fermentation or simultaneous saccharification and fermentation of high oil corn.

A bioprocessing facility that includes: a source of one or more stillage compositions; a multi-effect evaporator system including at least a final-effect evaporator; and an anaerobic digestion system in fluid communication with the final-effect evaporator. The final-effect evaporator is configured to receive at least a portion of at least one stillage composition as feed. The final-effect evaporator is also configured to produce a vapor composition and a concentrated stillage composition. The anaerobic digestion system is configured to receive and digest at least a portion of the concentrated stillage composition to produce a biogas and an anaerobic digestion digestate composition. The multi-effect evaporator system includes at least one effect evaporator prior to the final-effect evaporator that is configured to receive at least a portion of the anaerobic digestion digestate composition as feed. Related methods of producing biogas from one or more stillage compositions.

Methods and systems for using one or more stillage compositions generated at a bioprocessing facility for anaerobic digestion. Two or more anaerobic digestion digesters are configured with respect to each other based at least on the suspended solids content and soluble solids content of each process stream that is fed to each anaerobic digestion digester.
