Researchers say wasted coffee grounds could provide up to 340 Mgy of biodiesel

In Nevada, researchers at the University of Nevada-Reno have announced that coffee grounds, which have an 11-20 percent oil content by weight, could be the source of up to 340 Mgy of biodiesel. Grounds typically end up in municipal waste or are used as a soil conditioner, according to the research team, which added that coffee’s high concentrations of anti-oxidants could make coffee-based biodiesel more stable than fuels made from other feedstocks.
