Biomass has been considered as a potential raw material to produce biofuels. Most research studies have been focused on the production of bioethanol, while biobutanol offers better fuel properties than bioethanol and therefore, it is a more promising alternative for use in internal combustion engines. However, biobutanol production using biomass at industrial level is a difficult task, since the capital investment required is high in comparison with bioethanol. There are different pathways to produce biobutanol, that should be analyzed from a technoeconomic perspective to identify the most viable one. In light of that, a team of Colombian and Greek scientists, compared the two major biobutanol production routes, namely acetone–butanol–ethanol fermentation also known as ABE fermentation, and catalytic ethanol upgrading, to shed light on their technoeconomic attributes. The results revealed a better economic performance of the ABE fermentation with a production costs of 1.56 U.S.D. per ton, against 1.80 U.S.D. per ton, computed for the catalytic processes pathway. Moreover, the biobutanol yield and energy demand of the ABE fermentation process, were lower than those of the catalytic ethanol upgrading. From the environmental impact point of view, the conventional ABE fermentation process led to a lower potential environmental impact than the catalytic ethanol upgrading. Thus, ABE fermentation could be recommended as a more viable approach for industrial scale production of biobutanol from biomass, the minimum processing scale has to be higher than 1584 ton per day though.
