  • CenUSA Education Material
    Deana Namuth-Covert
    What is the CenUSA Bioenergy Project? The CenUSA Bioenergy project is funded by the USDA and includes faculty and staff from 8 institutions working together to investigate perennial grasses as a feedstock for biofuels and the creation of a regional sustainable biofuels system in the Midwest. CenUSA Bioenergy Vision Our vision is to create a regional system for producing advanced transportation fuels derivedfrom perennial grasses grown on land that is either unsuitable or marginal for row crop production.  In addition to producing advanced biofuels, the proposed system will improve the sustainability of existing cropping systems by reducing agricultural runoff of nutrients and soil and increasing carbon sequestration. To learn more about the CenUSA project, please visit the CenUSA home page at http://www.cenusa.iastate.edu/ To view the educational materials we have created thus far, click on the "lessons" tab above.  Find additional quizzes by clicking on the "CenUSA Education" link under the self-paced course heading.  The left hand tabs will take you to more detailed descriptions of the CenUSA project objectives.                                                                  The CenUSA Bioenergy project is supported by Agriculture and Food Research Initiative Competitive Grant no. 2011-68005-30411 from the USDA National Institute of Food and Agriculture.
