Agrofuels constitute the subset of liquid biofuels of the first generation, extracted from agricultural feedstocks, beside those awaited of the second generation extracted from renewable ligneous-cellulosic products (agricultural wastes, wood)1 or algae or micro-algae, often called of
the third generation. Although biogas from composting agricultural wastes (beside other organic matters) is also an agrofuel we will not discuss it as its usefulness is not disputed.
We will not discuss either feedstuffs to draft animals still used extensively in the traditional sector of developing countries (DCs).
Agrofuels encompass three products: bioethanol2, biodiesel and pure vegetable oil, of which we will hardly discuss as it is limited practically to Germany. Global biofuels production has surged exponentially since 2000 and reached 85 billion liters (Bnl) in 20083.
