IN BRIEF: Greener biofuel purifier
The Engineer A cheap, simple way of purifying biodiesel made from vegetable oils, which is also low in toxicity, has been developed by Leicester University chemists. It claims to be greener than traditional methods and provides a sustainable way to purify biodiesel without producing significant waste.The team, led by Prof Andrew Abbott, removes glycerol, the main by-product of vegetable biodiesel, using ionic liquids made in part by vitamin B4 (choline chloride). If left in biodiesel, glycerol would damage engines but this washes it out of the fuel.
