A common roadside plant could have the right stuff to become a new source of biofuel, according to U.S. Department of Agriculture (USDA) studies. Scientists with the Agricultural Research Service (ARS), USDA’s principal intramural scientific research agency, have found that Field Pennycress (Thlaspi arvense) yields impressive quantities of seeds whose oil could be used in biodiesel production.
The scientists obtained oil from wild field pennycress, pretreated it with acid, and used a type of alcohol called methanol to react with the field pennycress oil to produce both biodiesel and glycerol. After some additional refining, the finished biodiesel was tested to see if it met the biodiesel fuel standard established by the American Society for Testing and Materials. The results suggested that, with some work, the previously problematic pennycress could become a commercial commodity.
