Grass Clippings Q & A
Written by Scott Sklar   
September 09, 2007

Q:Hello, my name is Adam. My science fair project is on renewable fuels. to see whether grass clippings can be turned into alcohol and then used as a fuel source. Do you know of any ideas that might help me in my project? Do you know of any current research on this study?

A:

Adam, Thank you for writing. Turning glass clippings to ethanol is much harder than turning sugar, sugar beets or potatoes into ethanol that are already a starch. By mashing the starch and adding yeast - you can derive ethaniol, and by distilling the liquid ethanol (removing water), the ethanol becomes stronger. For grass, you will need to obtain either an enzyme or acid that can breakdown the cellolose within grass to sugar. I am not sure how easy that will be. You should contact the National Renewable Energy Laboratory (www.nrel.gov) to see how that might be done. Best regards, Scott Sklar
