Bio-fuel production in Iceland

The plastics would give between 7 to 10thousand tons of DME and the glycerol would give about 450 to 500 tons. The paper couldgive about 3400 to 3800 tons. Based on the pilot gasifier the amount would be slightly lowerfor these three categories.6. ConclusionsIt is safe to say that the raw materials that are available in Iceland today are enough forgasification and production of fuels from syngas to make a difference. The available organicwaste in the capital area along with Reykjanes, south and west of Iceland was estimated tobe more than 225.000 tons for the year 2010 and together with organic waste fromagriculture the amount could be 250 – 260 thousand tons.
