A high level of unsaturated fatty acids lowers the congealing point, not just for the oil/fat, but also for the resulting FAME. This is especially significant in connection with the use of pure biodiesel, while it is less important as regards admixtures.
Daka Biodiesel will primarily be produced using refined animal fat extracted from slaughterhouse by-products and dead animals from primary agriculture. Other by-products in the form of used cooking oil and other oils unsuitable for food production may also be used in the production process.
Denmark has a large animal production, and we must ensure that the by-products that are not of sufficient quality to end up on the dinner table are put to the best possible use.
For some people, the use of dead animals from agriculture will be controversial. These raw materials, however, are no different from those that reach the slaughterhouse. Traditional fossil fuels also stem from dead plants and animals, but we do not believe that we should wait 100 million years before the present by-products from agriculture can be recycled!
