Sharp Rise In German Biomass Pellet Prices
Friday, August 23, 2013 GLOBAL – Pellet prices in Germany have increased substantially the past year from an average of €227/ton in the second quarter of 2012 (2Q/12) to €267/ton in the 2Q/13. In the US South, pellet export volumes to Europe resumed their double-digit growth after a brief pause in the fourth quarter of 2012. TheBioenergySite News Desk Continue reading
The Elbert Files: Now Is The Time To Sell Farmland
BY DAVE ELBERT , Columnist Friday, August 09, 2013 7:00 AM Iowa’s farm economy is at a tipping point. This won’t be a collapse, like the farm crisis of 30 years ago, when farmland lost 60 percent of its value and many farm families were put off their land. But there are growing signs that the farm economy has peaked. And if it has, the effects will be felt well beyond the farm gate. In recent years, record-high crop prices boosted Iowa’s per capita income growth to levels well above the national average, as well as state income tax collections. “Indeed, it is in the cards” that a decade of growth in farm income is coming to an end, said Neil Harl, Iowa’s premier agricultural expert. “These spikes never last forever,” Harl said last week. “Farmers are the world’s best economic citizens. Give them half an economic incentive, and they increase production every time and drive the price down, and destroy their own economic prosperity.” That is what is happening now. Corn and soybean prices reached record levels for the month of January, but they are now down significantly. Crop prices can, and do, fluctuate during the growing season. But the trend this year is abnormal. In recent years, crop prices have typically increased during the late spring and early summer months, based in part on early flooding and drought fears. Then in late summer and early fall, prices fell when government reports predicted larger-than-expected harvests due to advances in plant genetics, changing weather patterns and other factors. But this year, Iowa’s corn and soybean prices are bucking that trend. Corn prices are down 30 percent from January, while soybeans are down 15 percent. In the past 30 years, there have been only three other times – 1975, 1994 and 1999 – when both corn and soybeans posted double-digit price declines between January and July. In two cases, 1975 and 1994, year-end prices wound up being even lower than the July averages. Those earlier events occurred before significant genetic advances created drought-tolerant and fast-growing crops capable of making up the difference when planting is delayed by spring flooding. No one can predict with certainty what will happen this year, but at this point, it is unlikely that prices will recover to last year’s record levels. If corn and soybean prices remain where they are now, they would chop roughly $4 billion off the value of Iowa crops that sold for more than $20 billion last year. Indeed, current prices are more in line with 2010, which was also a good year for farm income, although not as good as the two years that followed. The problem today – and it’s not a bad problem to have – is that the bar of expectations has been repeatedly raised in recent years. Expectations are a big driver in farmland sales, pushing up land values by leaps and bounds not seen since the years that preceded the 1980s farm crisis. Harl and others say a 1980s-style crash is unlikely for a variety of reasons. But the question remains, have farmland values peaked? “We haven’t seen it yet,” said Steve Bruere, president of Clive-based Peoples Co., a major broker of farm sales. But he added, most farmland sales occur between September and March. “There is still so much money in checking accounts, and land values always lag going down,” Bruere said. Another factor, he said, is “interest rates have jumped about 1 percent.” “Eventually, the combination of lower prices and (higher) interest rates will affect land values,” Bruere said. If you own farmland and want to sell at the peak, now is probably a good time. Read more: http://www.businessr…6#ixzz2cPXNPHGh Continue reading
One-Pot Process To Simplify Production Of Biofuel From Biomass
Details Category: Technology 16 Aug 2013 Published on Friday, 16 August 2013 The right combination of enzyme cocktail and ionic liquid pretreatment can be used to extract fermentable sugars from switchgrass in a single, wash-free step. (Photo by Roy Kaltschmidt) A “one-pot” method of processing biomass into biofuels has been developed by researchers with the United States Department of Energy’s Joint Bioenergy Institute. “By combining ionic liquid pretreatment and saccharification into a single vessel we eliminate the excessive use of water and waste disposal currently associated with washing biomass that that is pretreated with ionic liquids,” said chemical engineer Blake Simmons. Advanced biofuels made from cellulosic sugars stored in the biomass of grasses and other non-food crops and agricultural waste could substantially reduce the use of fossil fuels. In the United States alone, more than a billion tons of biomass are produced annually that could be potentially used to create cleaner and greener substitutes for fossil fuels. In order for advanced biofuels to be commercially viable however, they must be cost-competitive with fossil fuels. Currently, the processes to extract the sugars needed to formulate these fuels are costly and complicated. To process biomass, it must first be pretreated with an ionic liquid – environmentally benign organic salts – before adding an enzyme cocktail that breaks down the biomass into fermentable sugars. However, as most ionic liquids inhibit the enzyme cocktail, the biomass needs to be washed beforehand. “The recycling and waste disposal costs associated with this required washing pose a significant challenge for the commercial scale-up of ionic liquid pretreatment technology,” said Seema Singh, director of JBEI’s biomass pretreatment program. The JBEI team focused on the use of imidazolium-based molten salts in their one-pot processing method. Imidazolium is one of the most effective known ionic liquids for breaking down cellulosic biomass. “However, imidazolium, like other ionic liquids, can inhibit the commercial enzyme cocktails now used for the saccharification of cellulosic biomass,” said Ms. Singh. To meet this challenge, JBEI researchers developed a compost-derived consortium of bacterium that could grow on switchgrass, a popular biomass crop. The consortium was dubbed “Jtherm” and consists of several species of thermophiles, microbes that can thrive at extremely high temperatures and alkaline conditions. “Jtherm is both an ionic liquid and heat tolerant cellulase cocktail that can liberate sugars from biomass in the presence of up to 20-percent ionic liquids, “ said John Gladden, deputy director for fungal biotechnology at JBEI. The one-pot system uses imidazolium-based ionic liquid pretreatment on the switchgrass then adds Jtherm to extract the sugars. With this one-pot system, they liberated 81.2 percent glucose and 87.4 percent xylose over the course of a 72 hour processing at 70 degrees Celsius. They were able to separate the sugars at better than 90-percent efficiency. The team is now planning to scale-up tests of this one-pot system and is in the process of further optimizing the Jtherm enzyme cocktail and seeking to identify other ionic liquids that could be used in this process. – EcoSeed Staff Continue reading
