However, although the renewable alcohols can be produced from agricultural byproducts (cereal straw, sugarcane bagasse) the economics are even more unfavorable given the complex manufacturing process that includes fermentation and distillation.
This time lag cannot be explained by lack of engineering knowledge in Europe: the same countries were using mechanical threshers for virtually all their crops and seed drills had already been widely adopted. The difference was that labor was more abundant in Europe, farms were smaller, and the harvesting machines were therefore not profitable.
