Amazing stuff coffee. In addtion to it’s other amazing properties, including being good for the roses, the grounds can be used to produce biofuel.
The estimates are the coffee ground biodiesel industry could generate as much as $8,000,000 in profits annually using waste from Starbucks stores here in the United States alone. Ok, probably less given falling crude oil prices, but I’m still a big fan of any domestic fuel souces.
To add to the overall awesomeness of coffee, at the end of the biodiesel extraction and conversion process, the leftover grounds can be turned into fuel pellets for wood stoves and boilers.
Not only does coffee keep you moving, it can keep your car moving and heats your home!
Update: Crude prices have reversed the downward trend that was in place when this article was first posted (December 2008). They are now pushing $100 a barrel and don’t show any signs of slowing down. Starbucks brand biofuel made right here in the USA is starting to look like a good business opportunity.
