If ethanol is the primary product produced, dry mills offer the advantages of lower construction and operations costs, with improved production efficiency. Of the more than 70 U.S. ethanol plants currently being built, only a few are wet mills. The efficiency of ethanol production has come a long way during the last 20 years.

Two processes currently being utilized to produce ethanol from YDC are dry milling and wet milling. The wet mill process is more versatile than the dry mill process in that it produces a greater variety of products; starch, corn syrup, ethanol, Splenda, etc., which allows for the wet mill to better react to market conditions.

There are currently far fewer wet milling facilities than dry milling facilities in the United States. Data available in November, 2009 indicated that there were 180 corn or starch ethanol plants operating in the U.S. 173 of these plants processed corn and/or other similar grains, and only 11 of these used the wet milling process ( EPA, 2010 ).

Traditionally, ethanol from corn has primarily been produced through dry- and wet-milling processes. The majority of U.S. ethanol production is from dry-grind technology. The traditional dry-grind process grinds the whole corn kernel and mixes it with water and enzymes. The mash is then cooked to liquefy the starch further.

DCO coming from dry-mill ethanol plants is viewed more as a co-product. The entire corn kernel is ground up for fermentation, and the oil is spun out later from the syrup. The energy component used to create this co-product is calculated to be much lower than that of a wet-mill plant, therefore allowing it to be a viable feedstock to generate RINs.

These dry fractionation efforts always result in co-products with less purity than those produced by the corn wet milling process. Consequently the ethanol yield from a dry grind / dry fractionation process is negatively impacted as the result of fermentable starch exiting the process with the co-products.
