Value Chain

Our breeding programme is dedicated to both edible and non-edible Jatropha cultivars. The main objective of the non-edible cultivars is the production of Jatropha oil with an excellent quality. Main indicators for this are the oil content as well as the yield per plant. The edible Jatropha cultivars focuses in particular in a high protein content, which can be used for animal feed and food production. In both cases, the processing residues can be used to obtain several high value products.


Non-edible Jatropha

At present, the most common Jatropha processing steps include: de-husking of fruits - pressing of seeds - sedimentation and filtration of oil. The two main products gained hereby are high quality oil and press cake, both with interesting marketing possibilities. The high quality Jatropha oil is excellent both for direct use in engines (Straight vegetable oil, SVO) and the production of bio-fuels like bio-diesel and bio-kerosene. Soap production is another attractive utilisation option for the oil. The press cake is a good substrate for biogas production and an excellent organic fertiliser. The fruit husks as an additional by-product can be utilised as fuel pellets.

Jatropha - Research & Development

Besides the currently common utilisation pathway Jatropha provides various production opportunities. However, not all "utilisation pathways" are currently economically viable or technically feasible. As a company with a distinct focus on research and development, we are working intensively together with different partners on the following issues:

  •    Use of  biomass and residues (hemicellulose, cellulose, proteins, lipids, soluble lignin and lignin)
  •    Recycling of press cake with supercritical fluid extraction, alkaline and hot water hydrolysis
  •    Biotechnological utilization of the unsaturated fatty acids of Jatropha oil
  •    Innovative oil extraction, mechanical, enzymatic and aqueous extraction
  •    Reduction of GHG emissions and improve of soil quality / reduction of soil erosion
  •    Improved field management in combination with Jatropha curcas (pasturing, intercropping or greening)
