Modern Technology Ensures Top Quality Products

The use of by-products for the production of biodiesel presents a number of challenges as opposed to the use of pure plant oils.

The content of free fatty acids is significantly higher, which may lead to processing problems if these are not converted into fatty acid methyl esters before the conversion of the fatty substances. This means that the conversion process involves two stages: the first comprises an acid pre-estering using sulphuric acid as a catalyst and the second the re-estering of the fatty acids under alkaline conditions with the addition of an alkaline catalyst, typically potassium or sodium hydroxide.

The use of animal fats also requires an improved final refining process since it contains a number of micro-components that may present a sediment problem unless they are removed. The biodiesel is therefore subjected to a final distillation process where fatty acid methyl esters are fractionated into light and heavy fractions. This stage also ensures a low sulphur content in the final biodiesel (<10 ppm). In addition to biodiesel, the production process results in glycerine and potassium sulphate.

The processing plant was supplied by BDI, an Austrian company with a great deal of experience when it comes to establishing biodiesel production plants based on animal fats. SARIA’s ownership of Daka Denmark A/S and thus of Daka ecoMotion, also adds valuable expertise, since the company has constructed and operates several biodiesel plants in Germany.

Daka ecoMotion has also tested other catalysts in a test plant. These may provide certain advantages in processing terms, but for time reasons Daka ecoMotion has chosen to base its full-scale plant on tried and tested technology. Improvements may subsequently be incorporated as time passes.

Which Ingredients are Used in the Production?

Daka ecoMotion biodiesel will primarily be produced using refined animal fats extracted from by-products from slaughterhouses or primary agriculture. Other residual 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 residues from agriculture will be controversial. These raw materials, however, are no different from other raw materials. Traditional fossil fuels also stem from plants and animals, but we do not believe that we should wait 100 million years before the present by-products from agriculture can be used.

Research & Development

In order for Daka ecoMotion to maintain our strong position in the market, we continuously optimise and develop in the following key areas:

  • Sustainable raw material; mainly focusing on waste material
  • Production facilities: advanced process monitoring and new technologies add to capacity improvements and a reduction in processing costs
  • Product development: to make our products even more attractive to our customers. This pertains both to the main product EN 14 214 biodiesel and heavy bio heating oil and also to the by-products glycerine and potassium sulphate

All development projects are closely linked with the development strategy within the ecoMotion Group and is performed together with our suppliers, customers and research institutes.


Daka ecoMotion’s production plant has a separate Chapter 5 approval, which ensures that its impact on the surrounding environment is extremely limited. The actual biodiesel production process takes place in a closed system, and emissions are extremely limited. Biodiesel is also characterised by its high biodegradability as opposed to that of fossil diesel.
