Twenty companies, including Archer-Daniels-Midland Co and Cargill Inc, have been cleared to produce the new ethanol grade called E15, a significant step toward putting the higher blend biofuel on sale, the government announced on Monday.
Most fuel sold at filling stations is a 9-to-1 blend of gasoline and corn-based ethanol. The ethanol industry proposed E15, a 15 percent blend, three years ago.
