Biodiesel By-Product Excellent Swine & Poultry Feed
Biodiesel producers are looking for a market for a big by-product of the green fuel they make… livestock producers need a high-quality feed. Seems like they need to find a way to get together. Scientists at the U.S. Department of Agriculture are finding a new use for the glycerin produced during biodiesel refining.
This article from the April issue of USDA’s Agricultural Research Magazine says animal nutritionist Brian Kerr, who works at the ARS Swine Odor and Manure Management Research Unit at Ames, Iowa, William Dozier, formerly in the ARS Poultry Research Unit at Mississippi State and now with Auburn University, and Iowa State University colleague Kristjan Bregendahl are looking into how to use crude glycerin as a livestock feed supplement:
Kerr led studies that examined how crude glycerin feed supplements affected swine energy use. In five different experiments, he supplemented the diets of starter pigs and finisher pigs with different levels of crude glycerin…
Pigs fed the crude glycerin were able to digest it efficiently, and it provided them with a supply of caloric energy that basically equaled that of corn grain. A followup study showed no effects on weight, carcass composition, and meat quality in pigs fed diets containing 5 percent or 10 percent crude glycerin from weaning to market weight.
Meanwhile, Dozier and Bregendahl evaluated the use of glycerin supplements in poultry feed. They used 48 egg-laying hens and 1,392 broilers in 4 research studies.
After feeding four levels of crude glycerin to laying hens, Bregendahl determined the AME in the crude glycerin to be 3,805 kcal/kg. He also compared feed consumption, egg production, egg weight, and egg mass (calculated by multiplying egg production and egg weight) and found no significant differences among the four groups.
The scientists say the research has been successful, as the data shows that crude glycerin is an excellent source of energy for pigs and chickens and doesn’t harm animal performance, carcass composition, or meat quality. They do caution that while the glycerin is a great feed supplement, there are some issues that could limit its use, such as small methanol and salt levels.
But overall, this could be a real win-win situation with livestock producers finding a way to cut feed costs and biodiesel producers finding a way to add value to their products.



According to a POET press release, POET Biorefining in Bingham Lake, Minnesota, has used a new technology wich will eliminate water discharge providing a more efficient way to produce ethanol.
The 35 million gallon per year facility currently uses less water than average plants. Bingham Lake facility used 3.42 gallons of water to produce one gallon of ethanol. With zero-liquid discharge, that is cut by 23 percent, to an estimated 2.64 gallons of water per gallon of ethanol.
A landfill in Dallas, Texas will soon be the source of renewable biomethane that will be burned to create electricity.
“This gas sale agreement validates selling renewable biomethane as a valuable, low-carbon fuel. It provides Clean Energy with a sound, long-term revenue stream and also supports expansion of the plant’s production capacity for additional gas sales, including potential use as vehicle fuel,” said Andrew J. Littlefair, Clean Energy president and chief executive officer “Many of our largest customers are showing interest in biomethane for their fleet vehicles as it is one of the best alternative fuels to meet new Low Carbon Fuel Standards coming in California and other states.”
The nation’s leader in biodiesel making and making biodiesel plants has a new leader of its own.
Mr. Oh takes the reins from Nile Ramsbottom, who has served as Renewable Energy Group’s president since the company’s incorporation in 2006. Mr. Ramsbottom’s leadership helped launch REG as a premier producer and marketer of high quality biodiesel. In the nine years Mr. Ramsbottom has served at REG and its predecessor West Central Cooperative, the company’s biodiesel business has grown from a 1 million gallon-per-year batch plant to a network with the more than 300 million gallons of annual production capacity. Mr. Ramsbottom has agreed to forgo full retirement to help strengthen REG’s global presence. The new global sales position will be based in St. Louis.

“This project allows us to expand our internal and collaborative plant breeding activities in a region where we believe the industry will have a strong presence,” said Ceres plant breeding director Jeff Gwyn, Ph.D. “There’s a lot of headroom for improvement and I’m confident that working together we can continue to drive up yields at a robust pace,” he said.
