Abstract: A hemp biodegradable absorbent according to various aspects of the present technology comprises receiving hemp biomass and processing the biomass into a desired particle range through a separation process. The separation process may comprise an initial filtration to separate out particles having a size of greater than 500 μm, pulverizing or sifting the remaining particles into a plurality of grades in a range of 0.5 μm to 50 μm, and selecting at least one grade of particles to form the absorbent. The selected particles are dried to a moisture content of less than about 10% to create a hemp biodegradable absorbent base that can be used to form various types of absorbent products that may provide an absorbent capacity of between about at least about 300% and up to about 600% by weight. The hemp biodegradable absorbent may also be effective at absorbing both oil-based and water-based liquids.

Abstract: Processes and systems for recovering products from a fermentation mash. In some examples, a process for recovering products from a fermentation mash can include processing a ground corn product to produce a fermentation mash that can include ethanol. At least a portion of the ethanol can be separated from the fermentation mash to produce a whole stillage. The whole stillage can be separated to produce a fiber rich product and a filtrate. The fiber rich product can be hydrolyzed to produce a saccharification mash. The saccharification mash can be processed to produce additional ethanol and a stillage protein product.

Abstract: A method of producing sugar solution by repeating a sugar solution production process includes steps (1) to (3), wherein a wash solution obtained in step (4) of washing a separation membrane after step (3) is used for step (1) of subsequent sugar solution production processes: step (1): preparing slurry of pretreated cellulose-containing biomass; step (2): hydrolyzing the slurry of pretreated cellulose-containing biomass in step (1) using cellulase from filamentous fungi; and step (3): subjecting the hydrolyzate of step (2) to solid-liquid separation into a solution component and a hydrolysis residue, filtering the solution component through an ultrafiltration membrane and recovering the cellulase from filamentous fungi as a non-permeate, and recovering the sugar solution as a permeate.
