Biodiesel from Used Coffee Grounds

So here's the latest in biodiesel feed stock as a source for biodiesel. Used coffee grounds! Hell I drink enough that I could probably fuel a semi!

Some excerpts from the article:

"....Spent coffee grounds contain between 11 and 20 percent oil by weight. That's about as much as traditional biodiesel feedstocks such as rapeseed, palm, and soybean oil...."

"....Growers produce more than 16 billion pounds of coffee around the world each year........The scientists estimated, however, that spent coffee grounds can potentially add 340 million gallons of biodiesel to the world's fuel supply...."

Here's a link to the full article in Science Centeric web site.

I'm going to try to obtain a copy of the journal publication for complete details. Stay tuned!!
