Biofuel for planes may take off within 10 years

Within a decade, passenger planes will be flying on jet fuel largely made from plants — flax, marsh grass, even food waste — as airlines seek to break away from the volatile oil market and do their part to fight climate change, aviation experts said Wednesday.

Though biofuels are still in the experimental stage, the projected shift has stoked concern among environmentalists that the possible insatiable appetite of airlines for plant oil will hasten the destruction of tropical forests and the conversion of cropland from food to fuel.
