The main objective of the project was to improve knowledge about the utilisation of animal fat as raw material for production of biodiesel. The project contributed to increased knowledge about:
- Potential for biodiesel production through the exploitation of animal fat in Norway.
- The most important barriers to using animal fat for producing biodiesel, and developing strategies to overcome these barriers
The maximum potential of 162 kt biodiesel from used animal fat in Norway is 35 kg per inhabitant. If this factor is applied to all EU-25 with about 460 million inhabitants, the result is 16 200 kt biodiesel. This is almost 3 times the estimate by the European Biodiesel Board for the 2006 biodiesel production capacity, of 6100 kt for EU-25 . The lower potential, limited to new biodiesel production, is for 99 kt of biodiesel, or 22 kg per inhabitant in Norway. Applied to EU-25, as above, this could give 9900 kt biodiesel. Although the estimate for Norway on average biodiesel production per inhabitant is not directly applicable to EU-25, due to the relatively large fishing industry in Norway, we still can conclude that: Norway is in a good position for producing large amounts of biodiesel from animal and fish residues. It is however worth keeping in mind that the estimates for potentials from grease traps per inhabitants in Bergen, Oslo and Trondheim probably are too high to be representative for Norway as whole. Residual fat clogging up waste water pipes is a problem mainly for urban areas, with their high population densities. This implies that the density of grease traps per inhabitant probably is less in rural areas, than in the three largest cities of Norway. The magnitude of this error is however assessed to not significantly change the main conclusion above.
