FIGHTING THE DESERT & CREATING WEALTH

Editor’s Note: When this article was originally posted, in 2005, we were just becoming aware of the potential of biofuel. We had published
Hope in Jatropha about a year earlier, a thrilling story that described how this tough perennial tree could survive in the desert, and could actually stablize soil and combat desertification, at the same time as its beans could be refined for diesel fuel.

Then a few months later we posted the feature Europe Adopts Jatropha which described what seemed to be hopeful momentum towards increasing use of biofuels by the European Community. Since this time we’ve become concerned about the level of deforestation caused by biofuel. It’s one thing for biofuel to exist because of a competitive market, but quite another to allow subsidies and credit offets finance deforestation for biofuel. If you farm biofuel, beware, these subsidies and offset credits will go away the moment the Europeans realize they are financing destruction of forests.


The article to follow is valuable because it goes into some technical detail on Jatropha. But the yields claimed in this story have been challenged by many of our readers, and the author may have been optimistic. When you review the tables, insert your own assumptions regarding yield – consider these ultra best cases, if that. Rather than remove this feature, we’ve left it up because there is a lot of practical information that can help aspiring Jatropha farmers to consider. But where do you wish to plant the fuel crop? Somewhere it can fight the desert, or in a former rainforest? Because Jatropha in the desert will not yield much fuel per acre, and Jatropha where rainforest was will produce much better, at least at first. Eventually loss of the forest reduces precipitation, and these Jatropha crops will require more and more expensive irrigation. Do you want to fight deserts or create them?

We have removed the glowing enthusiasm of the ingenue that informed the first editor’s note to this feature. We scrapped the whole thing and replaced it with this cautionary note. Carbon offset credits are fueling the rainforest burning. In our opinion, continuing to destroy the tropical rainforests is far more harmful than, say, extracting heavy oil from Orinoco and burning it clean. If you want a few jatropha plants to attain energy independence for your farm or village, or are advancing into the desert with life, grow jatropha. Jatropha may or may not be such a good idea if you are looking to make tons of profit; there are many remaining technical hurdles to lower refining costs, and the money from subsidies and credits may stop. – Ed “Redwood” Ring, August 2007

Jatropha in Africa – Fighting the Desert and Creating Wealth
by Keith Parsons, August 21st, 2005

Jatropha curcus is unusual among tree crops.

Perhaps its most unusual feature is its modular construction. The dry fruits and seeds will remain on the tree for some time, before falling to the ground, especially under dry conditions. Benefits include but are not limited to:

Oil as raw material: Oil has a very high Saponification value and is being extensively used for making soap in some countries. Also, the oil is used as an illuminant as it burns without emitting smoke.

Medicinal plant: The latex of Jatropha curcas (VanaErand or RatanJyot) contains an alkaloid known as “jatrophine” which is believed to have anti-cancerous properties.

Raw material for dye: The bark of Jatropha curcas (VanaErand or RatanJyot) yields a dark blue dye which is used for colouring cloth, fishing nets and lines.

Soil enrichment: Jatropha curcas (VanaErand or RatanJyot) oil cake is rich in nitrogen, phosphorous and potassium and can be used as organic manure.

Feed: Jatropha leaves are used as food for the tusser silkworm.

In addition to these benefits, scientists at Perdue University in the U.S. and elsewhere are working in the extraction of usable pharmaceutical derivatives from Jatropha Curcas while others are attempting to grow non-toxic plants (Mexico).

Preliminary research indicates Jatropha may display certain Anti-Tumor properties, Anti Malarial properties and research is advancing related to HIV/AID’s and immune system response enhancement. There are other levels of use that can be exploited. Direct fermentation of seed cake and pulp delivers an organic fertilizer that has a high potential for export to developed countries.

It is in the field of Bio Diesel fuel, however, that Jatropha’s properties are the most exciting. At same power output, Jatropha curcas oil specific consumption and efficiencies are higher than those of diesel fuel. Tests conducted show that out of these various vegetable oils including copra, palm, groundnut, cottonseed, rapeseed, soya and sunflower – the lowest exhaust gas emissions were obtained with copra and Jatropha Curcas crude oil.

Areas in Africa Suitable for Jatropha
Over 50% of Africa’s land has the
right climate for growing Jatropha

HOW MUCH LAND IN AFRICA IS SUITABLE FOR GROWING JATROPHA?

In a survey conducted by Dr. Guy Midgley, Chief Specialist Scientist of the Kirstenbosch Research Center of of the South African National Biodiversity Institute (Cape Town) over 1,080 million hectares land Africa could be termed prime growing regions for Jatropha Curcas on the African continent. A further 580 million hectares could be used making a total of 1,660 million hectares suitable for the growing of Jatropha Curcas.

On the map of Africa the dark areas represent prime Jatropha growing regions in Africa. These areas, comprising over 1,080 million hectares, or 10.8 million square kilometers, are ideal because the average annual rainfall exceeds 800 mm, and the minimum temperature of the coldest month is greater than 2 degrees centigrade.

The light green areas of the map are areas with average annual rainfall in excess of 300 mm, with the minimum temperature of the coldest month greater than 2 degrees centigrade. These areas, comprising over 580 million hectares, or 5.8 million square kilometers, are also viable regions for growing Jatropha.

HOW MUCH REVENUE PER HECTARE CAN JATROPHA GENERATE PER YEAR?

Jatropha Facts
Jatropha Facts

Referring to the table, the yield per hectare per year is up to 8.0 tons of Jatropha seed, which contain over 30% oil. At $320 (US$) per ton, this will translate into sales of Jatropha crude oil of $768 per hectare per year. Of potentially equal or greater value is the yield from Jatropha seeds of glycerin. Up to 7% of Jatropha seeds are made up of glycerin, which sells for up to $2,000 per ton. This translates into glycerin sales of up to $1,120 per year per hectare, or total sales of up to $1,888 per year per hectare.

Editor’s note: In subsequent investigations we have not been able to corroborate the author’s claim of 8 tons per acre. Jatropha yields vary widely, but in no other example has such a high yield been reported.

Imagine, if only 3% of the land in Africa that is considered viable land to grow Jatropha was actually planted with Jatropha, with a yield of 8 tons per hectare per year and an oil content of 30% some 119 Million tons of Jatropha crude oil would be produced per year. The glycerin content at 7% of the 119 M tons would produce an additional 8.366 M tons. Glycerin is indeed a valuable by product.

In terms of annual revenues, if only 3% of the potential Jatropha growing regions in Africa were planted with Jatropha, based on a Jatropha crude oil price of $320 per ton and with glycerin selling at $2000 per ton a total sales value of $55 billion per year would be generated. Processing the crude oil into Bio Diesel would on average in Africa add a further 15% to the sales value. This sales value excludes other byproducts of Jatropha. Most African countries are oil dependent and foreign exchange expenditure would be reduced.

Jatropha farming could be an incredible contribution to economic development in Africa. Feasibility however is problematic due to the difficulty sourcing suitable financing. The two main reasons for failures to source funding are:

1) Land in many countries in Africa is not owned but leased. This effectively eliminates land being used as collateral by funders.

2) Start up agriculture projects are generally among the most difficult projects for which to obtain funding.

Moreover, financial models show that an assured supply of feed stock is required from a central area to ensure a viable project. Only when this is assured can out growers be considered to supplement the main supply chain. Projects where only marginal land is to be used will be very border line and unlikely to financially succeed. Good yields on marginal land are highly unlikely to be obtained.

WHAT ARE CHALLENGES TO JATROPHA’S COMMERCIAL VIABILITY?

There are still some inherent problems with Jatropha and research work is still required. We are learning more and more about the properties of Jatropha. These potential problems include:

1) Jatropha oil is hydroscopic – absorbs water and needs nitrogen blanketing on steel tanks. One issue that is quite clear is because Jatropha is high in acid, it has the tendency to degrade quickly, particularly if not handled properly through the supply chain.

2) Right from the time of expelling, the oil needs to be kept in storage conditions that prevent undue degradation. Exposure to air and moisture must be minimized – hence the need for nitrogen blanketing on the tanks.

3) The range of fatty acids present in the various seeds will differ but the oil and biodiesel that is produced must be acceptable. However, this assumes that that oil is fully degummed. The degumming may well be more of a problem than making biodiesel!

4) The phospholipid, protein and phorbol ester contents in edible Jatropha seem to be quite different compared to these contents in non-edible Jatropha. It needs to determined if this affects the degumming method. The degumming removes lecithin and other related compounds, so if these are high than a modified degumming method may be needed. If the oil is properly dried after degumming and kept under nitrogen blanketing this may suffice. Biodiesel companies are investigating storage requirements and the oxidative stability of Jatropha.

5) Seeds degrade as soon as they are picked and so careful storage and handling is required. In the warm humid atmosphere in countries such as Ghana the degradation of seeds can be rapid. Even in the U.K. seed storage is a problem. Recently a U.K. importer had samples of rapeseed that had been harvested and stored in wet weather. The analysis showed that they had 28% of free fatty acid! The free fatty acid must not increase above 2%.

6) There has never been a highly commercial group handling Jatropha Curcas harvest and derivatives.

Rubber Nitrile tanks are perfect for container shipping as there is no exposure to the atmosphere or the air, this is because they are collapsible and always work in a vacuum. They can be fitted in a 20ft – 30 ton container. Each container would hold about 22.4 tons Jatropha Curcas crude oil. Their use would prevent the problem of water absorption.

World Wide manufactures of Bio Diesel processors are beginning to recognize the need for their units to be able to accept more than one variety of vegetable oil. The pre-processors, (de-gumming units) must be designed to be “multi disciplinary”. Commercial Bio Diesel processors are expensive and it is financially essential for feed stock to be available on a continuous basis. Harvesting is seasonal and storage time has to be minimal due to the free fatty acids having to be no more than 2%.

Feasibility studies ideally need to be done but this is far too time consuming. The bio-diesel entrepreneur would need to take some statistical chances. By growing at the same time alternative crops to Jatropha curcus the problems may be somewhat reduced.

It makes sense that a bio-diesel entrepreneur should focus on the promotion of partnerships and in-house activities that support multiple crop development and improvement activities as well as seeking the add on values that are available.

Climate change will grossly increase African’s poverty levels. A Bio Diesel 1 Group initiative introduced Stancom Tobacco to the benefits of growing Jatropha curcas for conversion into Bio Diesel. The photos in this article show the Stancom Tobacco’s nurseries in Zambia. The harvested seed will be collected by BD1 Malawi and processed into crude oil.

Subject: Jatropha vs Pongamia

Sir,

Your article is excellent. Certainly we should go in for Bio-Diesel. My point is which is most suited for Indian Conditions. Jatropha or Pongamia. Pongamia is native to India whereas Jatropha is an Imported one. Why not we encourage Pongamia cultivation. Is there any other problem or issues involved in it? Please do reply.

Thanks,

Karuppan Gnanasambandan

EDITOR’S REPLY

Karuppan,

I have forwarded your inquiry to some people involved in jatropha production and indeed Pongamia is already well known as a plant to cultivate for bio-fuel. We will investigate this further and hopefully have some reports for you on the differences between these plants.

Thank you for your email,

Ed Ring

    I’m very much interested in the information on Jatropha, but the major problem in our country is that not even the government has a concrete policy on it.
    The ministry of energy talks bout Jatorpha but does not give the lead way:
    1). The best seeds
    2).Where to market the seeds.
    3). Machines to proceess the jatropha curcus.
    With all these handcaps, many farmers may resort to cutting down the trees.
    I’ m a good example.
    So give us more information especially marketability.
    Thank you.

    Developing countries have been a ground for testing projects and as a result, many have failed and we have remained the victims. I Uganda, afew years ago,all the message was about growing Vanilla and indeed we did but hardly five years, there was no market for the cash crop after many had acquired loans to grow vanilla. I have the following question;
    1. Jatropha is being promoted by the already developed nation who will definitely determine the prices, how secure are the farmers?
    2. Like other cash crops, soon we shall see the supply of fertilizers to boost the production which will cause a permanent damage on the soil. What strategies are in place before we promote the crop?
    3. In Uganda, 17million people do not have enough to eat and so are other developing countries but the demand for land from developed nations is so high to grow crops for fuel, how beneficial do you think jatropha will be to a poor man/woman.
    4. Where has Jatropha been successful in the world at least for 10 years that we have experience from farmers who have done it before?
