Bio-based plastics, chemical alternatives, ethanol: ADM does it all. Revenues rose almost 20%, to $44 billion, and net income increased 65%, to $2.2 billion. With corn prices rising, though, the "dot-corn" ethanol phenomenon is losing some of its glow, and the stock has fallen sharply. Still, strong global demand positions ADM's commodity-based businesses well for the long haul.
