Uses ethene from oil to produce pure ethanol. Uses expensive equipment to produce.

what's fermentation?
C6H12O6-->2C2H5OH+2CO2. Yeast produces enzymes to convert sugars into ethanol+carbon dioxide. When solution reaches 15% ethanol, yeast dies. Fractional distillation used to increase conc of ethanol. low tech, it uses cheap equipment+renewable stuff
