Re: [Biofuel] Jatropha Curcas Where
Hi Ires,The India Jatropha is non edible, so the cake is not for animal flodder, the edible specie is comming from Costa Rica or Nicaragua and Mexico, can not help you with adresses. WE buy in India and crop it in Tanzania, the pressed cake and the nutshell we press in briquettes to replace the Charcoal which is the biggest de-forresting, and enviromental, killer fromthe woods in Africa and S.America.If you can not find edible, there is a chemical way to clean the non edible, you will find it on the internet. greetings and a good and healthy new year for allMartin Roozenburglres1 [EMAIL PROTECTED] wrote: Arden and all,Thank you for your suggestion but so far have been unable to locate any place that sells Jatropha seeds from Mexico, they all seem to be from India and am not sure if they are the toxic or non-toxic seeds.The mail system here is very slow.

Re: [Biofuel] jatropha curcas
Hi Isabel Hi Keith It seems as if you don't think it is a good idea to use Jatropha as a source to produce bio diesel from? I think whether it's a good idea or not depends entirely on the immediate context of where you're planning to grow it. One of the replies you got warned you against the silver bullet approach. There's no magic bullet, the crop that gives the best results is the one that fits the local circumstances best, the more local the better. Like all crops, jatropha curcas has its pros and cons, some of them were also pointed out to you: I grew Jatropha in Ruwa, about 30 km from Harare, and they did quite well there. What I found with them is the seed is very difficult to get out of the outer shell but maybe you can invent or buy a machine to do that part of the job. Have you thought of using Leucaena? -- Jed, Mozambique Jatropha is hardy and has a highish yield but it's also toxic. The seedcake (what's left after pressing) cannot be fed to animals. Why not convert it to biodiesel? It's better in the long run. -- Duncan, South Africa This is also in the archive, along with much else: A critique of Jatropha in India by Ashden Award winner, Pune-based botanist Dr. A. D. Karve, president of the Appropriate Rural Technology Institute (ARTI) in Maharashtra, India: http://www.mail-archive.com/biofuel@sustainablelists.org/msg48290.html Our number one choice to manufacture bio diesel from is Jatropha Curcas but we have been unable to obtain seeds locally or from any of the countries surrounding us.(South Africa) Both Jed and Duncan told you where you could get seeds, two different places, did you try them? When I originally posed the question I only received a few messages and none of them was negative. Maybe I missed something! Maybe! Do you really think those two replies are positive? As I originally explained we know nothing about producing bio diesel and that is why we posted our original questions and gave a brief explanation why we though it would be best to use jatropha. We have literally read every article we can find about producing bio diesel and to date have not found in our opinion any crop better suited for us to produce bio diesel from, as a matter fact it seems from what we have read that jatropha is the number one choice world wide to produce bio diesel from. I'd suggest you do a little more reading. You obviously have a lot of experience knowledge regarding producing bio diesel as well as what to use to do so. I wouldn't claim that, I think we're all learners. Therefore If you believe jatropha is not the way to go it would be greatly appreciated if you would say so why you think so, because as I have said before we are asking for advice and if you have reasons to believe that jatropha is unsuitable I would like to know about them so as to enable us to make a fully enlightened decision. I think I've said so many times, and why. The List administration told you the same thing when you joined, and made some good suggestions, but you didn't seem to notice. There is no best crop, if you think there is then you're starting in the wrong place and asking the wrong questions. Too often the result of that is that if anyone benefits it's not those who were intended to benefit, or it's at their expense. IMHO the choice isn't between jatropha and soy, it's more about the kind of project you want to do. Please see: http://journeytoforever.org/community.html Community development http://journeytoforever.org/community2.html Community development - poverty and hunger How come your reading on biodiesel hasn't revealed to you the disadvantages of soy? Eg.: Apart from our normal interest in Bio diesel in general, we are thinking of planting soybeans to manufacture bio diesel from. Try a good old browse in the list archives to find out why soy biodiesel fails to meet the European biodiesel standard. How're you planning to get the oil out of the soy, with hexane? Hardly village-friendly. Beste Keith Kind regards.

Hi Isabel I heard today that castor beans are an excellent source of biodiesel. Does anyone know if this is true? Marilyn Er... http://snipurl.com/kia1 biofuel - Search results for 'castor' 255 matches Eg: Brasil is going ahead with great biodiesel project in large scale production such as 4 l/day using peanut oil in cane growing areas in south, medium scale plants palm oil in Amazonian areas .Medium scale prodution using castor oil in North east underdeveloped area in Brasil , mostly by federal and state government. The federal goverments Petrobras is going to install big scale plant based on castor plants that wiil be grown on treated waste water from petroleium production based on caster seeds in dry semiarid areas with less developed area with large poor people . - Pannirselvam, 6 Aug 04 ... The B2 fuel that the government will authorise in November will require an additional 150,000 hectares of oilseeds, which will generate a source of income for 30,000 families of small farmers, said Minister of Agrarian Development Miguel Rossetto. Biodiesel is leading to the promotion of the cultivation of castor beans and other crops in semiarid lands in the northeast, Brazil's poorest region. Projects involving family farms in small rural communities are spreading in the region, opening up possibilities of reducing poverty and curbing the rural exodus to urban slums. The Brazilian Company of Agricultural Research (EMBRAPA), a government network of 40 research centres, has carried out studies to help promote the expansion of castor bean cultivation. Biodiesel based on castor oil will not only serve as fuel, but will also be used to generate electricity in isolated rural communities, at least in the northeastern state of Ceará.

Re: [Biofuel] jatropha curcas
Hello Doug, Isabel, Edible provenances of Jatropha curcas from Veracruz and Quintana Roo States of Mexico were investigated by Makkar, Becker and Schmook of the University of Hohenheim and found to be non toxic to humans after roasting. Phorbol esters, the major toxic constituents of Jatropha, were altogether absent in three of the seed samples and the contents of trypsin inhibitors, phorbol esters, phytate were all lower in the roasted nuts, which tasted like roasted peanuts. However, lectin activity was not reduced by roasting. They concluded that this non-toxic variety could be cultivated in developing countries for their edible oil, and seedcake as fodder. http://www.jatropha.de/schmook1.htm The presence ofa new tumor promoter in theseed oil of JatrophacurcasL has been reported in theJapanese Journal of Cancer Research by Hirota M, M Suttajit et al from Thailand but there is not much else besides this singular study. A debate is now on in the new state of Chattisgarh in India about the advisability of cultivating Jatropha because of this. http://southasia.oneworld.net/article/view/113032/1/1897 Those interested in Jatropha would do well to visit www.jatropha.de run by the redoubtable Reinhard Henning (who incidentally, used to post to this list- please see archives) andThe Centre for Jatropha Promotion www.jatrophaworld.com The former site provides links to Jatropha developments in Egypt, Ethiopia, Ghana, Madagascar, Mali, Malawi, Namibia, Republique de Cote de Ivoire, Senegal, South Africa, Sudan, Tanzania, Tunisia and Uganda besides other countries.

Just my caution and pessimism. Peace -Kurt Kudzu is excellent fodder for grazing animals, high protein, as good as alfalfa and more productive. Good pasture, and it makes good hay. It's a legume and fixes a lot of N,generally a soil improver. It's a deep-rooter and brings up a lot of minerals from the deep subsoil. It produces large, starchy tubers, widely used as food in the East and elsewhere in the tropics. It's also excellent at stabilising steep slopes, and as a general anti-erosion crop. The best way to eradicate it is to turn it into, first, beef, and second, pork. After the cattle are done, the pigs will root the rest out in search of the tubers, manuring as they go, leaving very fertile soil for the next crop. Americans and also Australians seem to hate the stuff, but where I've seen it growing wild in the East it has not been a pest. I've never heard it referred to as a pest here.

Re: [Biofuel] Jatropha Curcas
Hi BellaBok Sounds like a cool plan. You don't have to get the seed from India, you can get it from Zimbabwe at the government nursery in Harare. If you know any people who live in Harare, ask them to go to the government nursery and speak to David in the seed dept. I have seen it growing here in Quelimane, Mozambique, where we are living at the moment and I could probably get some seed down to you if you gave me your address, we have guys from South Africa travelling back and forth all the time. I grew Jatropha in Ruwa, about 30 km from Harare and they did quite well there. What I found with them is the seed is very difficult to get out of the outer shell but maybe you can invent or buy a machine to do that part of the job. Have you thought of using Lucinia (don't know how to spell it). I am not sure of the oil content but I think the tree will do well in your hard conditions. I am sure you have hundreds of goats in that area so it will be good as goat feed as well as giving you oil and you can feed the seed cake to the earth worms as well. Your problem will be keeping the goats out of the plantation while the trees are trying to grow. I can get some of this seed to you as well, it grows here. Good luck with your plan.

Re: [Biofuel] Jatropha Curcas -
Hi Isabel, 2. We have ordered seeds from India and we intend planting these seeds and once the trees are old enough we take cuttings from them, we will supply the local people with these cuttings so that they will be able to establish small plantations. Apparently Jatropha grows easily from cuttings and the cuttings produce fruits earlier than Jatropha planted from seeds. Mafikeng Biodiesel, together with Invest North West and the Barolong Boora Tshidi Development Company, has established a nursery to grow Jatropha near Mafikeng, I haven't seen it but by all accounts it's impressive. Have a look at http://www.biodiesel.co.za. I'm told that 45000 ha has been made available, oil from this is enough for a 26000tpa plant. Not quite home brewing but lots of jobs in the growing and processing. 3. Once again we will assist the local people to establish simple hand presses that would be able to press the fruit and the oil once filtered can be used directly in there tractors and stationery engines. We will teach them to start up on normal diesel and then switch over to the Jatropha oil once the engines are warm and to switch back to diesel again before shutting Why not convert it to Biodiesel? It's better in the long run. While all you need to know is at http://www.journeytoforever.org/biofuel.html I'd be happy to share what I've learnt about finding raw materials etc. People who do not have tractors or engines can sell the oil or the fruit on the open market. Jatropha is hardy and has a highish yield (http://journeytoforever.org/biodiesel_yield.html) but it's also toxic. The seedcake (whats left after pressing) cannot be fed to animals South Africa imports a large quantity of seedcake annually. I found this http://www.jatropha.de/ and this http://www.ecoworld.org/Home/Articles2.cfm? TID=367 interesting. 5. Oh! I nearly forgot we are up in the north eastern section of South Africa (Limpopo province) the area were we are is supposed to be sub tropical but the last 4 years has been very dry and we have not received any where near our normal rainfall and this year so far is the worse. Limpopo is the poorest province in South Africa. One advantage we have is that there is large tracts of land that can be used for planting and the quality of the soil generally is not bad, now all we need is for our normal rainfall to return. The Agricultural Research Council (ARC) is looking at setting up a biodiesel training spot near Marble Hall - using sunflowers as the raw material. 6.One of the reason we are thinking of using Jatropha is because we understand it grows in all conditions and will even grow in semi arid regions, it never goes below 8 degrees Celsius here. I understand the jury is still out, from a Department of Agriculture and Dept of Water Affairs point of view. There is concern about encouraging the growth of alien plants without doing research on the impact it will have on water resources. I do have an article on this somewhere I'll try and find it and post the link. 7. Locally there are no sources of used vegetable oils etc. to enable us to try and make bio diesel so we will wait until we are able to produce our own oil and them learn how to convert it to bio diesel. I'd encourage you to try and set up you own processor it was a little more expensive but I made my first few batches with virgin oil I bought - off the shelf. There are many other reasons that we are thinking of going exclusively with jatropha but you must understand that we are only going on what we have read and have no practical experience and would appreciate any input and advice from anyone as we do not want to disappoint the local people, to them it would be a tremendous boast if this plan can work. As you will see if you lurk around this list good biodiesel can be made by anyone. I think it's a great, empowering concept for people to become self reliant in a commodity that has always been representative of 'first' world domination.

Why do you want to plant a monocrop? Monocrops aren't sustainable - you'd want to produce sustainable biofuels via unsustainable ag methods? Anyway, do an archive search for jatropha (without the quotes), there's a lot of information there: http://infoarchive.net/sgroup/BIOFUEL/ Including this: Jatropha curcas is a good option, but there are many other good options. The idea that it's the best option just doesn't take into account how development projects work, if they work at all, and this type of best technology thinking is one reason they often don't work. Almost any locally grown crop would have more going for it, regardless of Jatropha's yield and general usefulness. That's no reason not to use Jatropha, but it has to be fitted in properly, and once again full local involvement is essential for that to happen. Best Keith Yahoo!
