Earlier this month I wrote about the London bus system which is testing the use of coffee extract as part of the fuel used by its diesel buses. It turns out that incorporating waste products into fuel is not new. Parallel Products, a California company, has been doing it for thirty years. The waste it uses comes from wine, beer, tainted liquors and flat colas. According to its website “Each year, Parallel Products receives and recycles over 13 million cases and 3 million bulk liquid gallons of unsaleable beverage products.”
