Iowa edged Nebraska on Wednesday for a ethanol plant to be built by DuPont that would use corncobs, leaves and stalks as feedstock rather than corn, the Des Moines Register reports.

The plant will be built in Webster or Story County and will join a proposed Poet facility at Emmetsburg as Iowa’s two “next-generation” refineries.

DuPont and partner Danisco hope to begin service at the plant by 2013.

Every $1 million invested in biomass-generated power could yield $7.4 million in income and about 97 jobs, according to a report published by Plains Justice, an environmental advocacy group.
