Abstract: Integrated processes are disclosed for reducing the carbon foot print related to the use of non-renewable hydrocarbon gas streams for producing alcohols by anaerobic bioconversion of reformed gas. These processes combine renewable and non-renewable gas sources of hydrogen, carbon monoxide and carbon dioxide to produce alcohol. Thus the invention found a highly a practical way to make use of non-renewable carbon oxide sources while still lowering the carbon footprint of such alcohols produced thereby, especially when combined with corn ethanol production. In the case of motor fuel use, the renewable portion of the alcohol produced in this manner provides a reduction in greenhouse gases by 50% or more when compared to gasoline.
