Crude glycerin (CG) is a byproduct of the biodiesel chain, every ton of methyl-ester produced generating approximately 0.1 tons of CG. According to the International Renewable Energy Agency, total biodiesel production in 2012 was more than 2 million tons of CG. 1,2,3-propanetriol (aka glycerol) is the main component of CG. Synthetic glycerol, which the carbon is generally fossil-based, is a high-value and commercial chemical with thousands of different applications; global demand was 1.99 mega tons in 2011 and this is expected to reach 3.06 mega tons by 2018 (Transparency Market Research, 2014). For these reasons, the industrial valorization of CG from biodiesel production is gaining interest in order to recoup part of the production cost of biodiesel and therefore to promote biodiesel industrialization on a large scale
