  6. Uses of Jatropha cake for biogas • 70–75% of the seeds are produced as oilcake; • The cake is high in organic matter; • Biogas production from Jatropha oilcake was about 60% higher as compared to that from cattle excreta; • Biogas generated from Jatropha oil cake has better calorific value than cattle excreta because it has more methane.

  7. The Cinderella Plant NEWSWEEK feb 19, 2007 issue Is it true?

  8. Brazilian actions to support the development of Jatropha Curcas • Normative Instruction n XX, authorizes the inscription of the specie Jatropha Curcas in the Ministry of Agriculture; • Creation of Jatropha Curcas Research Board;

  9. EMBRAPA genetical breeding program on JC • Productivity • Toxicity • Fruit maturation line process

  10. Other uses • Recently experimentation on solid-state fermentation of Jatropha seed cake showed that, it could be a good source of low cost production of industrial enzymes; • The oil and aqueous extract from oil has potential as an insecticide; • Investigation of the coagulant activity of the latex of Jatropha, showed that whole latex significantly reduced the clotting time of human blood.

  11. Conclusions • The Jatropha industry is at a very early stage of development, though there are vigorous efforts to promote it, if successful, will alter the picture considerably; • The energy value of remaining portion of Jatropha fruit is twice that of biodiesel.
