Green Coffee
Drinking coffee for a good cause…
Well, if you believe everything you read on the internet. According to the Guardian, Coffee is next in line as biofuel source:
Coffee grounds — currently wasted or used as garden compost — could become a cheap and environmentally friendly source of biodiesel and fuel pellets….. Scientists at the US-based University of Nevada, Reno, used an inexpensive process to extract oil from the leftovers of making espressos, cappuccinos and other coffee preparations from a multinational coffeehouse chain.
Great, now I need to watch for the coffee machine and thieves.
