Coffee Grounds

<h3 >Biodiesel from used coffee grounds</h3>

<p >Researchers at the&nbsp;<a href="http://en.wikipedia.org/wiki/University_of_Nevada,_Reno" title="University of Nevada, Reno" >University of Nevada, Reno</a>, have successfully produced biodiesel from oil derived from used coffee grounds. Their analysis of the used grounds showed a 10% to 15% oil content (by weight). Once the oil was extracted, it underwent conventional processing into biodiesel. It is estimated that finished biodiesel could be produced for about one US dollar per gallon. Further, it was reported that "the technique is not difficult" and that "there is so much coffee around that several hundred million gallons of biodiesel could potentially be made annually." However, even if all the coffee grounds in the world were used to make fuel, the amount produced would be less than 1 percent of the diesel used in the United States annually. “It won’t solve the world’s energy problem,” Dr. Misra said of his work.<sup id="cite_ref-102" class="reference" ><a href="http://en.wikipedia.org/wiki/Biodiesel#cite_note-102" >[100]</a></sup></p>
