Swiss specialty chemical company Clariant announced January 29 that it partnered with Haltermann and Mercedes-Benz in order to demonstrate the effectiveness of its branded “sunliquid” cellulosic ethanol derived from wheat straw at a 20% concentration in conventional gasoline (E20) to assess optimal driving performance on the biofuel blend. Over the next year, test fleet vehicles will be refilled with the new fuel at a specially-equipped gas station on a Mercedes-Benz site in Stuttgart-Untertürkheim, Germany. The cellulosic ethanol will be provided by Clariant’s demonstration-scale production unit located in Straubing, Bavaria (southern Germany), where about 4,500 metric tons of agricultural residues such as grain straw or corn stover are converted into cellulosic ethanol each year.
