A recent world concern is generating renewable energies and biodiesel appears as an important form to diversify the energy matrix of several countries in the world.
Currently countries that are big fuel consumers, such as the United States, have begun to invest in biodiesel as an energy alternative with the perspective of producing 5 billion liters biodiesel in 2014 and Europe around 12 billion liters biodiesel.
Assuming that for each 19 liters of biodiesel produced, 10 liters of crude glycerin are generated, it is estimated that in 2014 the United States will produce around 500 million liters crude glycerin and Europe something around 1.3 million liters crude glycerin.
