The importance of increasing the global share of biofuels in transportation goes without
saying. Iceland, where the consumption of fossil fuels is considerable, has a viable
potential for introducing biodiesel in its otherwise exceptional renewable overall energy
In this study, a full picture of the possibilities of biodiesel production in Iceland was
provided. After the theoretical introduction of allmajor aspects of a biodiesel economy, an
assessment of its applicability in Iceland was performed.
A survey of potential feedstocks was performed. It was concluded that in a short term
perspective, a small scale production (300-2,000 tons/yr) can be carried out using
domestically available waste raw material, and fullscale production (15,000-80,000
tons/yr) will depend on imported feedstock.
After laboratory research, including waste vegetable oil (WVO), the main domestic
feedstock currently available, the recommendation for the production process of a small
production plant was made. It includes acid esterification of free fatty acids (FFA)
followed by alkali transesterification and methanolrecovery from the reacted mixture. At
this stage, distillation of crude FAME was suggested, however further research is
The full scale production could substitute 8%-44% of the fossil diesel fuel needs for
transportation and machinery. The estimated production costs in a full scale biodiesel
plant, 0.63-0.76 EUR/L, are within the European average.
