Production of ethanol from biomass

摘要

A method and apparatus for the production of ethanol from non-virgin biomass having deleterious materials therein is provided. The deleterious materials prevent or retard the production of ethanol 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 when the biomass is combined with the fermentation material.
