Probably the biggest issue facing biodiesel producers today is what to use as a feedstock. With soybean prices going through the roof, refiners are trying to find additional feedstocks. During the recent National Biodiesel Conference and Expo in Orlando, Florida, the last general morning session focused on the question of what to use for the green fuel.
The forum, led by Alan Weber, economic consultant to National Biodiesel Board, with Dr. Jack Brown from the University of Idaho, Keith Bruinsma, Vice President of Corporate Development for ethanol producer VersaSun, John Sheehan, Vice President of Strategy and Sustainability for Live Fuels, and John Soper, Senior Research Director for Soybean Product Development for Pioneer International.
Brown, who is Scottish, brought a European perspective and made the case for feedstocks made from non-traditional (at least in America) oilseeds, such as rapeseed. Bruinsma talked about how you can also get biodiesel from the same grain of corn used to make ethanol, while Soper talked about high oil corn and soybean seeds his company is developing. Sheehan, whose company makes biodiesel from algae, pointed out that they can get thousands of gallons for every acre of green pond scum they grow.
But most importantly, all of them agreed that ALL of the feedstocks are necessary, and no one gets ahead by tearing down the other guy. It wa’s a good point, and a great discussion.

“Understanding the land use changes occurring around the globe is important to developing strategies to combat the advance of climate change. However, like previous studies, those published in Science today fail to put the issue in context. Assigning the blame for rainforest deforestation and grassland conversion to agriculture production solely to the renewable fuels industry ignores key factors that play a greater role. The continued growth of the global population, surging global demand for food from expanding middle classes in China and India, and continued expansion of development and urban sprawl are all factors contributing to the increased demand for arable acres.”
The science of ethanol can now be taught in the classroom in an informative and entertaining way with the 

Last month, the young company made a splash at the North American international Auto Show in Detroit where a strategic partnership with General Motors was announced.
According to Dave Vander Griend, president and CEO of ICM Coskata’s thermal biomass conversion process offers promising technology.
“The bottom line is that the energy balance of biodiesel has definitely improved in the last decade,” says University of Idaho Department Head of Biological and Agricultural Engineering Jon Van Gerpen, who credits Assistant Professor Dev Shrestha and graduate student Anup Pradhan for their work on the study. “The increase in soybean yields and a decrease in herbicide use greatly contributed to the increased energy balance. Meanwhile, energy used for crushing soybeans is significantly lower than what was reported in the NREL study.”

He says that food items where corn and soybeans play a major role only account about 25 percent of the food basket.
The three-year study will focus on land use in North Dakota, South Dakota, Nebraska, western Minnesota and northern Iowa. “If you look at one of the maps by the Renewable Fuels Association, the hotspot of the activity is in this area,” said professor Geoff Henebry, a senior scientist in the Geographic Information Science Center of Excellence (GIScCE) at SDSU.
