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.The performance of such wet biomass (animal waste) systems is outlined in Agriculture and Autonomous Power Supply, EOLSS on-line, 2002, and summarized in Table 3. Autonomous power supply must also include human and animal power (as discussed in Human and Animal Powered Machinery, EOLSS on-line, 2002) which, although of great relevance to small farms in the poorest regions, is otherwise declining in relative importance.
