Valero Explores Renewable Energy
Valero Energy Corp. has spent almost $750 million buying 10 ethanol plants in the past 14 months, but those purchases didn't signal the end of the company's investments in renewable energy...
...Also last year, Valero took a stake in ZeaChem. of Colorado, which develops biorefineries that can convert biomass, including forest waste, into fuels and chemicals. Next year, ZeaChem expects to start producing cellulosic ethanol at a biorefinery in Oregon.
