This investigation showed that it was feasible to link the alcohol fermentation and anaerobic digestion processes into a system for the production of both alcohol and methane from organic substrates. The rate of ethanol production has been determined with respect to cell concentration and yeast recycling has been shown. Ethanol fermentation under reduced pressure has been shown to be feasible and to give higher ethanol productivities. The fermentation spent wash and extracted crop residues could be anaerobically digested to produce methane (and carbon dioxide). The methane produced could be used either in-plant for process heat requirements or out-of-plant in local or regional energy schemes.
