Final rule published for sorghum pathways

By EPM Staff | January 16, 2013

Grain sorghum ethanol now qualifies as a renewable fuel and, in some cases, an advanced biofuel, under the renewable fuel standard (RFS). The U.S. EPA published the final rule in mid-December.

According to the EPA, its analysis determined that when grain sorghum ethanol is produced at dry mill facilities fired with natural gas, the 20 percent greenhouse gas (GHG) emission threshold for renewable fuel is met, qualifying it for RFS compliance use. Where grain sorghum ethanol is produced at dry mill facilities, that use specified forms of biogas for process energy and most electrical production, the resulting fuel achieves GHG reductions of more than 50 percent, qualifying the ethanol as an advanced biofuels for RFS compliance purposes.
