Hi
can anybody tell me wether glycerin made from the Jatropha
Carcus(Physic nut) is Toxic or not. I want to use Jatropha oil for making
biodiesel. I want to know wether glycerin obtained from this process has the
same market value as glycerin produced from other oils. Information on
Jatropha is found at www.jatropha.org
Regards
Raj
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.

By the way, you might be interested in this post to the Stoves list
at REPP on jatropha from a researcher in India.

Dear Mr. Seaver,
I have conducted field experiments on both castor and Jatropha. I had
already mentioned in a previous E-mail, that Jatropha was tested rather
widely in India and was given up because it was not found to be as high
yielding as the traditional oil crops in India. I do not know how it
behaves in other countries, but under our agroclimatic and edaphic
conditions, Jatropha produces much more vegetative matter than fruits. At
harvest, one has to search for the occasional fruit hidden behind all the
foliage that this plant produces. It is found all over India as a wild
plant. India has some 25 uncultivated species of trees that yield
non-edible oil. The seed of the wild trees is collected by villagers and
sold to merchants attending the weekly village markets, but no farmer would
ever think of growing them as a crop, because all of them are lower yielding
than the cultivated oil plants such as peanut, soybean, sunflower,
safflower, sesame, various mustards and rapes, coconut, etc. Among the
seasonal oilseeds, hybrid castor is the highest yielding (2.5 tonnes oil per
ha), but it is not an edible oil. The highest yield of edible oil, also
about 2.5 tonnes per ha, is obtained from coconut. Oil palm, which yields 6
tonnes of oil per hectare in Malaysia, was tested and given up as low
yielding under Indian conditions.
Yours A.D.Karve
