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.

A method for producing ethanol from non-virgin biomass, comprising: providing non-virgin biomass containing convertible biomass and deleterious material, the deleterious material present in an amount sufficient to inhibit conversion of the convertible biomass in the non-virgin biomass to ethanol; removing at least a portion of the deleterious material present in the non-virgin biomass, thereby producing primary processed non-virgin biomass; providing virgin biomass, the virgin biomass being substantially without deleterious materials; combining the primary processed non-virgin biomass with a sufficient amount of the virgin biomass such that remaining deleterious material in the non-virgin biomass is diluted to an extent that conversion to ethanol and byproduct of the combination of the primary processed non-virgin biomass and the virgin biomass can be realized; treating the combination of the primary processed non-virgin biomass and the virgin biomass with hydrolysis and fermentation materials such that conversion to ethanol and byproduct occurs from the combination of the primary processed non-virgin biomass and the virgin biomass; and separating the ethanol from the byproduct.
