Abstract
A method and apparatus for the production of ethanol and other fermentation products including citric acid, butanol and isopropanol from non-virgin biomass having deleterious materials therein is provided. The deleterious materials prevent or retard the production of ethanol and other fermentation products when the non-virgin biomass is combined with a fermentation material. The method includes primary processing, secondary processing and/or blending the non-virgin biomass with virgin biomass such that the effect of the deleterious materials is reduced, thereby allowing production of ethanol and other fermentation products when the biomass is combined with the fermentation material.
