U.S. Department of Agriculture (USDA) plant physiologist <a href=\"http:\/\/www.ars.usda.gov\/pandp\/people\/people.htm?personid=34761&amp;pf=1\" target=\"_blank\">Steven F. Vaughn<\/a> and his colleagues have shown that litter made with these grains as the starting material may prove to be more environmentally friendly than popular but nonbiodegradable clay-based litters. After use, clay litters mostly end up in landfills.<\/strong><\/p>\n<div>\n<p>Spent grains are also known as DDGs, short for &#8220;dried distiller&#8217;s grains.&#8221; A DDGs-based litter may provide a new and perhaps higher-value market for the tons of DDGs that corn ethanol refineries now primarily market as a cattle feed ingredient.<\/p>\n<p>In preliminary studies, Vaughn&#8217;s group tested &#8220;x-DDGs.&#8221; These are DDGs that, after being used for ethanol production, are treated with one or more solvents to extract any remaining, potentially useful natural compounds.<\/p>\n<p>The team&#8217;s laboratory experiments yielded a suggested formulation composed of the x-DDGs and three other compounds: glycerol, to prevent the litter from forming dust particles when poured or pawed; guar gum, to help the litter clump easily when wet; and a very small amount of copper sulfate, for odor control.<\/p>\n<p>The resulting litter is highly absorbent, forms strong clumps that don&#8217;t crumble when scooped from the litter box, and provides significant odor control, according to Vaughn. He&#8217;s based at the Agricultural Research Service (ARS) National Center for Agricultural Utilization Research in Peoria, Ill. ARS is USDA&#8217;s chief intramural scientific research agency.<\/p>\n<p>The idea of using corn or other grains as the basis of an environmentally sound cat litter isn&#8217;t new. But the Peoria team may be the first to extensively study the potential of x-DDGs as the primary component of a litter, and to make their results publicly available.<\/p>\n<p>Their peer-reviewed scientific article about the litter appears in a 2012 issue of <em><a href=\"http:\/\/www.journals.elsevier.com\/industrial-crops-and-products\/\" target=\"_blank\">Industrial Crops and Products<\/a><\/em>.<\/p>\n<p>Vaughn did the work with ARS chemists <a href=\"http:\/\/www.ars.usda.gov\/pandp\/people\/people.htm?personid=34764\" target=\"_blank\">Mark A.
