  • Reality check for `miracle` biofuel crop

    The hardy jatropha tree as a biofuel source may not be the panacea for smallholders that some have claimed, say Miyuki Iiyama and James Onchieku. It sounds too good to be true: a biofuel crop that grows on semi-arid lands and degraded soils, replaces fossil fuels in developing countries and brings huge injections of cash to poor smallholders. That is what some are claiming for Jatropha curcas, ...

  • Yield projections for Switchgrass as a Biofuel Crop

    While scientists have conducted numerous studies on production of biomass from biofuel crops, such as switchgrass, no one has yet compiled this information to evaluate the response of biomass yield to soils, climate, and crop management across the United States. A team of researchers from Oak Ridge National Laboratory and Dartmouth College published just such a study in the July-August 2010 ...

  • Biofuel crops increase carbon emissions

    The conversion of forests and grasslands into fields for the plants offsets the benefit of using the fuel, researchers find. Greenhouse-gas output overall would rise instead of fall. The rush to grow biofuel crops -- widely embraced as part of the solution to global warming -- is actually increasing greenhouse gas emissions rather than reducing them, according to two studies published Thursday in ...

  • Crop management to reduce biofuels` carbon debt

    It is widely considered that using biofuels produces less greenhouse gas (GHG) emissions than using fossil fuels. However, there are concerns that the possible effects of land use change (LUC) may outweigh these benefits. New research looks at the effects of sustainable crop management as a means of reducing the negative impacts of LUC. Biofuels form an important part of the EU's strategy for ...

  • Growing Sorghum for Biofuel

    Conversion of sorghum grass to ethanol has increased with the interest in renewable fuel sources. Researchers at Iowa State University examined 12 varieties of sorghum grass grown in single and double cropping systems. The experiment was designed to test the efficiency of double cropping sorghum grass to increase its yield for biofuel production. The author of the report, Ben Goff, found that ...

  • Controversy over biofuels grows

    New research suggests that nitrous oxide (N2O) emissions associated with growing some biofuel crops may be much greater than previously thought and could be high enough to outweigh the potential CO2 savings associated with biofuels. Producing fuels from crops such as rapeseed is one strategy being explored to replace fossil fuels, with a view to reducing greenhouse gas (GHG) emissions from the ...

  • From Mules to Biofuels

    Farmers and policymakers are wrestling with two main concerns when it comes to ethanol production: the effect of ethanol demand on food prices, and changes in land use that are detrimental to the environment. While families were sharing corn at backyard barbecues this summer, both issues perked up ears across the globe. The Environmental Protection Agency rejected Texas Governor Rick Perry's ...

  • Algae-Based Biofuels Gets Big Name Backers, Cash Infusion Boost

    NEW YORK, NY -- (Marketwire) -- 08/17/10 -- Solazyme, one of the world's leading developers of algae-based biofuel has announced that they have secured $52 million in funding. Big investors include Morgan Stanley and oil giant Chevron, to name a few. Solazyme, unlike many other biofuel developers who find it difficult to get biofuels out of the lab, has been able to deliver on a deal with the ...

  • Analyzing long-term impacts of biofuel on the land

    The growing development and implementation of renewable biofuel energy has considerable advantages over using declining supplies of fossil fuels. However, meeting the demands of a fuel-driven society may require utilizing all biofuel sources including agricultural crop residues. While a useful biofuel source, crop residues also play a crucial role in maintaining soil organic carbon stock. This ...

  • Seaweed study boosts prospects for marine biofuels

    Seaweed biofuel farms have come a step closer to reality with an improvement in the way seaweed sugars can be converted to ethanol. Dried seaweed can be fermented to produce ethanol but breaking down galactose, the dominant sugar in seaweed, is a slow process. Now, researchers have modified the expression of three genes of the yeast Saccharomyces cerevisiae, which is used in the fermenation ...

  • Evogene Expands Biofuel Activity in Brazil With SLC Agricola

    Evogene Ltd. (TASE: EVGN) and SLC Agricola (BOVESPA: SLCE3) (PINKSHEETS: SLCJY) (BLOOMBERG: SLCE3:BZ) (REUTERS: SLCE3.SA), a leading agribusiness company in Brazil, today announced expansion of their agreement for the development of castor bean seeds as a cost competitive feedstock for biofuels. This expansion follows successful completion of field trials for such varieties in northeast Brazil ...

  • Genetic engineering could cut the cost of biofuels

    Plant genetic engineering could play a major part in reducing the cost of biofuel production from food crop wastes such as rice straw or from non-food crops such as willow and poplar. A recent study suggests further research is needed to develop plants that are better suited for biofuel production, through genetic modifications. According to the study's author, biofuels have the potential to ...

  • Biochemist studies oilseed plants for biofuel, industrial development

    A Kansas State University biochemistry professor has reached a milestone in building a better biofuel: producing high levels of lipids with modified properties in oil seeds.  Timothy Durrett, assistant professor of biochemistry and molecular biophysics in the College ...

  • FAO calls for review of biofuel policies and subsidies

    Biofuel policies and subsidies should be urgently reviewed in order to preserve the goal of world food security, protect poor farmers, promote broad-based rural development and ensure environmental sustainability, FAO said in a new edition of its annual flagship publication The State of Food and Agriculture (SOFA) 2008. “Biofuels present both opportunities and risks. The outcome would depend on ...

  • OECD and FAO see lower farm prices - livestock and biofuels outpacing crop production

    The recent fall in prices of major crops is expected to continue over the next two years before stabilising at levels above the pre-2008 period, but markedly below recent peaks, according to the latest Agricultural Outlook produced by the OECD and FAO. Demand for agricultural products is expected to remain firm while expanding at lower rates than in the past decade. Cereals are still at the core ...

  • Biofuels could increase food production, says report

    Planting biofuel crops in Africa need not damage capacity to grow food and could even enhance food security, according to a controversial review prepared for the Forum for Agricultural Research in Africa (FARA). The report, with case studies on six countries in East, West and southern Africa, concludes that bioenergy production can expand across the continent and provide income and energy to ...

  • Rice serves up double measure of biofuel and fodder

    Japanese scientists have found a potential answer to the biofuel dilemma that if you grow crops for energy, you have to sacrifice crops for food. They report that they can now ferment rice to deliver ethanol, while making silage for cattle feed –and that it can all be done on the farm without need for any expensive off-site processes. Mitsuo Horita, of the  ...

  • Protecting soils and producing biofuel with corn stover

    Those lonely cornstalks—called corn stover—left behind in the fields after the grain harvest is complete could someday become valuable raw material for the production of cellulosic ethanol. In the meantime, Agricultural Research Service (ARS) soil scientist Doug Karlen is determining which portion of the plant would work best for cellulosic ethanol production. He's also studying the amount of ...
