Customized Coproducts Needed as Industry Matures 

Corn oil extraction creates DDGs variability and new opportunities 

By Joseph Riley | June 06, 2011 

As we continue to see maturation in the distillers grain 

industry, the impact of corn oil is gaining momentum. In 2006, 

there were only four dry mill ethanol plants extracting corn oil 

from their process, and oil values were in the 12 to 15 centsper-pound range. Contrast that with this April, when there 

were about 50 plants extracting oil at a value approaching 50 

cents per pound. While food-grade corn oil has been a kitchen 

staple around the world for many years, the use of nonfoodgrade corn oil was uncertain at best in the first few years of 

extraction. 

With five years of experience, the current market for this corn 

oil is maturing at a rapid rate. Whereas initial deliveries of this 

oil were predominately into the animal feed market, we now 

see a significant portion being used at biodiesel facilities 

across the Midwest. The 2011 resurgence of biodiesel has 

nearly doubled the value of extracted oil, though what will 

happen after the expiration of the tax credits for biodiesel in 

December is unknown. With almost 20 percent of plants 

extracting corn oil (with many estimates showing up to 40 

percent by the end of 2011, and 55 percent by the end of 

2012), the normal DDG variability has dramatically increased 

to a point that the product may be considered unmanageable 

by some animal nutritionists. This variability is the largest 

reason why DDGs have been consistently undervalued 

compared to competing feed ingredients. 

Most plants sell their DDGs as they come out, purchased by the 

closest livestock producer or facility that will take them, pricing the DDGs based on a market price that day. In 

short, ethanol producers are giving livestock producers a reason to call DDGs a by-product and place it in the 

“commodity” category. 

As many industries such as food processors and petroleum have shown in the past, individual component values 

are significantly higher than the value of a combined stream. While past performance cannot dictate future 

results, the goal should be that DDG value be maximized by splitting the individual constituents of DDGs into 

purified streams. Most of this cannot be accomplished with existing processing and infrastructure, but corn oil 

extraction can be the first step in accomplishing this goal. 

While many facilities have been able to extract oil without having to discount their DDG price, this phenomenon 

will likely end in the near future. With the maturation of the DDG feed market, many consumers are becoming 

more aware of the value, and will likely demand discounts with reduced oil levels. This doesn’t mean that oil 

extraction should be left by the roadside. Instead, corn oil extraction should be strategic to the customer served 

by each individual plant. With the high density of plants within the Upper Midwest, the issue inhibiting a 

differentiated product mentality is customer defection. The commodity mentality has created a mental model 

with our customers that one plant’s product is the same as another. So if one seemingly reduces its value by 

extracting oil, they will immediately defect to the next plant in line. Most ethanol plants sit idly by while this 

happens. 

In reality, not all livestock producers require the same DDG components. Hog producers prefer DDGs with less 

corn oil to reduce the softness of fat in the belly and jowl and also see the value of the energy component as a 

positive attribute. One ethanol facility recently lost a local customer for DDGs when it began extracting corn oil. 

It turned to a lower-value export market. Yet the value of the oil was far higher than the difference between 

local and export markets. Meanwhile, a hog producer up the road had just removed DDGs from its ration. The 

high level of corn oil they were receiving in the DDG from another ethanol plant was causing the packer to 

discount their hogs because of soft belly fat. 

With tightening margins within ethanol production, the producers need to reconsider their mental model of 

profitability. Instead of focusing 95 percent of their energy on alcohol production, they need to focus on being a 

true biorefinery. There are enormous opportunities to create custom products to meet customer demands, but 

existing plants have limited process control outside of alcohol production. This is the root cause of variability in 

DDG composition and quality, and until more measurement is completed, there will not be significant 

improvements. With increased process measurements and control, the probability of producing a higher value 

product is vastly improved. What is difficult to communicate and grasp is the fact that there is no “right” product 

out of the ethanol coproduct stream. By understanding what causes the nutritional variability in their own DDGs, 

a plant can identify methods to reduce this variability, thereby contributing to a higher value product stream. 

This would help a facility to recapture whatever value is lost in the “as-shipped” DDGs due to corn oil extraction, 

and still capture the full value of extracted oil. 

While the majority of ethanol plants are centrally located geographically, the opportunity for these plants to 

service dramatically different customers is available. In an ideal world, an ethanol plant would have 15 individual 

product streams that would enable facilities to custom blend individual loads based on customer demand. The 

mentality of one-size-fits-all DDGs needs to be banished from the industry, and the commoditization mantra 

needs to be eliminated. There will likely never be consensus among animal nutritionists on what the ideal

composition of DDGs for feeding is, even within one animal group. Ethanol plants need to produce what their 

customers want instead of just providing them with whatever is pushed out the backside of the plant. With 

increased segregation of constituents, the ability to custom blend can be presented to customers. This will 

maximize value to the plant and to its customers. 

There are several companies working to re-engineer DDGs to achieve a higher value, more consistent and 

specifically tailored DDG. If the ethanol industry looks to food processing as its model, it will see that as markets 

mature, a purified stream has become more valuable than a mixed stream. This is true because it allows for 

flexibility, manageability, marketability and most importantly, customization. Livestock producers would, 

understandably, much rather take the constituents of DDGs supplied at their local ethanol facility and formulate 

a ration that is best for the species, the season and the system employed. 

FEC Solutions, founded in 2006, provides innovative corn oil marketing solutions as well as a market for fats and 

oils for specialty processing. The aim of FEC Solutions is to provide solutions to the biofuels industry which 

enhance ethanol producer margins and promote stability and consistency in the marketplace for livestock 

nutrition products.
