Review paper Integration of Biodiesel and bioethanol processes: Convertion of low cost waste glycerol to bioethanol

The once abundant petroleum reserves now dwindling and oil prices continue to rise; the search for alternative fuels becomes more vigorous. The paper reviews current growing attention focusing on ethanol as a renewable fuel to substitute and/or complement gasoline fuel. This trend is due to, among o...
