Move over, BioWillie. Scientists at the University of Nevada at Reno are researching the possibility of converting used coffee grounds into inexpensive biodiesel.
For the study, the team collected leftover grounds of espressos, cappuccinos and other coffee preparations from the Starbucks coffee chain.
Being that the process is not particularly energy intensive, the researchers estimated that biodiesel could be produced for about a dollar a gallon. …
“We have found that biodiesel created from spent coffee grounds is stable over a longer period of time than other forms of biodiesel that have been created from feed stocks such as soy and corn,” Misra said. “Biodiesel from spent coffee grounds is a low-cost ‘green’ form of fuel that shows a significant reduction of carbon dioxide emission. It’s an excellent source for biodiesel.”
As an added bonus, the resulting exhaust smells like — you guessed it — coffee! Finally, a reason to enjoy my morning commute!
OK, time for another cup of joe. Y’know, just saving the planet and all.
