If there are two things people are addicted to, it’s coffee and oil. For years, scientists and inventors have been looking for cheaper, more efficient ways to provide both humans and their cars with the energy they need.
Now, it seems that microbiologists Richard Sparling and David Levin have developed a method for using discarded coffee cups to feed ethanol-producing bacteria.
Traditionally, ethanol is extracted from food sources such as corn and wheat; however, this method is much more economical. Like most coffee drinkers, the bacteria show brand preference: Tim Hortons cups are preferred to Starbucks in the production of coffee cup biofuel.
