Abstract
Biomass from ethanol whole stillage and processes for making same are disclosed. The process overcomes the challenge of dewatering the stillage through the use of a press aid or a mixture of the stillage and unfermented biomass. The invention further provides a system and method for producing distillers peels pellets from fermented citrus waste. The invention allows the composition characteristics of the animal feed or bio fuel to be varied and optimized by controlling the mix proportions of the feedstock.
