Abstract
This disclosure describes a method for retrofitting an existing plant. The method includes adding a fractionation process to separate bran from other components in a feedstock to the existing plant, adding a pretreatment process downstream of the fractionation process, the pretreatment process configured to receive the bran and utilize water and heat to break down cellulose and hemicellulose in the bran; adding a hydrolysis and cellulosic fermentation process downstream of the pretreatment process and upstream of the fermentation process to hydrolyze the bran with a cellulase enzyme complex cocktail and to ferment with an organism to produce cellulosic beer; and combining the cellulosic beer with starch from the grain in the existing plant into the fermentation process to increase overall yield per feedstock unit in the existing plant.
