Corncobs may play major role in ethanol

SANTA ROSA, Texas, July 24 (UPI) — Secret testing in a secluded field near the Mexican border is aimed at meeting an expected huge need for ethanol — made partly with corncobs not corn.

In tiny Santa Rosa, Texas, a few miles northwest of Harlingen, the nation’s largest producer of ethanol, usually with corn, is seeking a new phase in creating a usable substitute for gasoline. And, in this case, a substitute for corn, as well.
