Hello Raj I suggest you should ask Reinhard Henning that, who runs the jatropha site. His address is: [EMAIL PROTECTED] But I should think it wouldn't be the glycerol fraction that's toxic, and once it's split off from the triglyceride and refined, it should be fine. If it's not refined, well, I don't know. If you simply separate the FFA and catalyst from the glycerine you should have industrial-grade glycerine of about 95% purity. You might be able to sell it as-is to refiners. http://journeytoforever.org/biodiesel_glycsep.html Separating glycerine/FFAs By the way, you might be interested in this post to the Stoves list at REPP on jatropha from a researcher in India. >From: "A.D.
