ABSTRACT

Worldwide production of biofuels is growing rapidly. From 2001 to 2007, world production of ethanol tripled from 20 billion litres to 50 billion litres (F.O. Licht, 2009), and world biodiesel production grew from 0.8 billion litres to almost 10 billion litres. The production of biodiesel in Europe is growing more rapidly than the production of ethanol, with a 2007 level of almost 6.2 billion litres of biodiesel and only 2.2 billion litres of ethanol (F.O. Licht, 2009).
