The three stages that have been put forth to make biofuels more sustainable - viz., engineering of plants, better processing facilities, more efficient conversion of plant oils into biofuels - are quite logical…

Some amount of research activities are taking place in each of the three stages…in fact, one of the interesting areas of research that has accelerated in recent times is exploring producing biodiesel from algae ( see Biodiesel from Algae)…for ethanol, an interesting area of exploration is production of ethanol from feedstock such as switchgrass
