The most common feedstock used in the production of biodiesel are vegetable oils, however, cultivated land is today limited to grow enough seed-oil plants. Due to the indirect land use and food vs. fuel issue, the utilization of these feedstocks for biodiesel production has been criticized (Austic et al. 2010). Feedstock accounts for 70% of the price of biodiesel (University of Alaska Fairbanks 2006). Hence, there is a need to fi nd cheaper feedstocks.
