Iranian engineers develop biorefinery for castor without need for fossil-based methanol
In Iran, chemical engineers have found a way to produce biodiesel from castor oil without the need for extra petrochemical methanol, using a biorefinery set-up. Producing biodiesel from vegetable oils is not completely renewable, as the standard transesterification process requires the use of methanol, which is usually produced from petrochemical sources. The researchers, Hamed Bateni […]
