USDA report shows that DDGS are more nutritious pound-for-pound

POET produces 10 billion pounds of animal feed per year through dried distillers’ grains with solubles (DDGS), but a new USDA study shows that DDGS replace a much larger proportion of corn and soybean meal in feed markets.

It’s an often-overlooked fact that ethanol production uses only the starch portion of the corn kernel, leaving the protein-rich portion for animal feed through DDGS.

A USDA study released this month titled “Estimating the Substitution of Distillers’ Grains for Corn and Soybean Meal in the U.S. Feed Complex,” found that pound for pound, DDGS are more nutritious than corn

“Findings demonstrate that, in aggregate (including major types of livestock/poultry), a metric ton of DDGS can replace, on average, 1.22 metric tons of feed consisting of corn and soybean meal in the United States.”

When you hear that “ethanol uses 40% of the corn crop,” it’s not accounting for that return of animal feed. About 40% of that corn used for ethanol goes right to livestock.

Another interesting point is that more DDGS are being used to replace soybean meal. Whereas the corn used for ethanol is not edible for humans, soybeans are. In a sense, DDGS are replacing edible food with inedible (to humans) feed. That actually frees up soybeans for human consumption.

The scientist behind Inviz

Today, POET announced a new co-product from the ethanol production process: Inviz. Inviz is a protein called zein, that is extracted from Dakota Gold HP at POET's ethanol production facility in Scotland, S.D. The protein is a renewable ingredient that can be used instead of petroleum-based ingredients in films, packaging, adhesives, coatings and glazes, as you can read in the release.

The announcement is another step from ethanol production facility to full biorefinery. But how did POET arrive at this place? The answer is largely found in the career path of POET Senior Scientist John Lawton.

Lawton has spent his career working on zein, much of it at the National Center for Agricultural Utilization Research at USDA ARS in Peoria, Ill. That extensive research has made him one of the world's foremost experts on zein. In fact, the Wikipedia entry for zein lists three papers authored or co-authored by Lawton. Those are just a few of the 32 peer-reviewed journal publications and five book chapters that Lawton has authored on zein and related topics and he is also responsible for four patents.

Recognizing that expertise, POET hired Lawton almost three years ago so that he could lead the company's efforts to develop commercial production of zein. The two had collaborated on zein research a few years prior to Lawton's arrival at POET.

For his part, Lawton wanted to come to POET because he recognized that the way POET produced ethanol resulted in a co-product that was a better starting point for zein. The Dakota Gold HP distillers grains produced with POET's proprietary fractionation and "no-cook" technologies of BFRAC and BPX, contains a protein that hasn't been damaged by heat. As noted in the release, Lawton is excited to see the commercialization of his life's work in the lab.

Take a look at this video from POET TV of Lawton explaining zein and the advantages of Inviz:

This is one of the many people at POET working on many renewable products that can displace those made from fossil fuels. To keep up with our progress, keep visiting this blog and follow us on Twitter.

The Ethanol process in the Indy Star

The Indianapolis Star had a front page story today on the food and fuel debate that has surfaced in our nation's capitol over the past few months. I'll post more on this debate soon and how some very wealthy corporations are trying to pin the blame for food inflation on ethanol production, but I wanted to call attention to an interesting photo gallery that accompanied the story.

The photographer made a trip to our newest plant, POET Biorefining Alexandria (Ind.) in conjunction with the story. Photos 1-8, and 12 are of the plant and include some great shots of corn being dropped off at the plant and the process of loading out Dakota Gold distillers dried grains with solubles.

It's fitting that the story include shots of DDGS, because they are often forgotten in the fog of the food and fuel debate. Our industry produces ethanol from the starch in the corn kernel and concentrates the fat, fiber and micro-nutrients in a high-protein animal feed - DDGS. Industry-wide, that animal feed will replace the need for 1 billion bushels of corn for animal feed.

Dakota Gold exhibit at World Ag Expo

POET Nutrition is in California this week and not just for the warmer weather. We’re exhibiting Dakota Gold, the highest quality most consistent DDGS available worldwide, at the World Ag Expo in Tulare. World Ag is the world’s largest agricultural exposition, with 2.6 million square feet of exhibit space, and over 1,700 exhibitors. From the picture here (with permission from the World Ag web site), you can get an idea just how big this event really is. During the week, Dakota Gold will be exposed to more than 100,000 attendees from over 67 countries. For daily coverage, check out the World Ag web site.
