The conversion of the Agri-Energy ethanol plant in Luverne, Minn., to isobutanol production could begin by the end of June, said David Glassner, an executive vice president for Gevo, which acquired the facility in September. "Obviously, there's the normal things that have to come together. We have to have our permits in place, and we have to have our detailed engineering, and we have to commit to the cost that it's going to be," Glassner said. The plant will produce ethanol until the conversion is finalized, Gevo said.
