Jatropha: The biofuel that bombed seeks a path to redemption

by Sean Mowbray on 6 April 2023

Earlier this century, jatropha was hailed as a “miracle” biofuel. An unassuming shrubby tree native to Central America, it was wildly promoted as a high-yielding, drought-tolerant biofuel feedstock that could grow on degraded lands across Latin America, Africa and Asia.

A jatropha rush ensued, with more than 900,000 hectares (2.2 million acres) planted by 2008. But the bubble burst. Low yields led to plantation failures nearly everywhere. The aftermath of the jatropha crash was tainted by accusations of land grabbing, mismanagement, and overblown carbon reduction claims.

Today, some researchers continue pursuing the evasive promise of high-yielding jatropha. A comeback, they say, is dependent on cracking the yield problem and addressing the harmful land-use issues intertwined with its original failure.

The sole remaining large jatropha plantation is in Ghana. The plantation owner claims high-yield domesticated varieties have been achieved and a new boom is at hand. But even if this comeback falters, the world’s experience of jatropha holds important lessons for any promising up-and-coming biofuel.

At the beginning of the 21st century, Jatropha curcas, an unassuming shrub-like tree native to Central America, was planted across the world. The rush to jatropha was driven by its promise as a sustainable source of biofuel that could be grown on degraded, unfertile lands so as not to displace food crops. But inflated claims of high yields fell flat.

Now, after years of research and development, the sole remaining large plantation focused on growing jatropha is in Ghana. And Singapore-based jOil, which owns that plantation, claims the jatropha comeback is on.

 Jatropha oil again?

After being silent for a while, I got triggered by the rising interest for Jatropha oil.

Not as a biofuel; most of these ambitious projects failed, as I uncovered before.

There is a more realistic approach to develop a business  case for the use of Jatropha products on a local scale.

This means not only biofuels (as going to be used in safari diesel cars in e.g. Tanzania) but also Jatropha soap being produced in Zimbabwe and exported to e.g. Germany.

This means not only producing seedcake briquettes in stead of charcoal for fuel but also seedcake as a fertilizer (https://jatropha.pro/seedcake-as-fertilizer/) and actually again for soap production and eventually for cardboard production.

The Jatropha market is merely hampered by several problems.

1.      The ambitious business plans of big companies were utterly unrealistic.

2.      There was a story buzzing around Jatropha that because the oil is poisonous, you could not use the seedcake in agriculture and you could not use oil or seedcake in health products like soap.

3.      The university of Katesart in Thailand proved already a long time ago that seedcake is a safe organic fertilizer and even better than chicken manure. See link for the complete study

           There is a lot of  anecdotical information that Jatropha soap works as an antibacterial treatment and a proper prevention for eczema .

5.       So far I did not run into scientific studies affirming the above mentioned claims, but still the soap is sold in the UK end Germany.

LET US TRY TO REVIVE THE PRODUCTION OF JATROPHA PRODUCTS FOR THE SAKE OF LOCAL COMMUNITIES IN AFRICA AND ASIA.

Jatropha diesel in Mozambique

At least one company in the world is proud enough to announce that their jatropha production is successful.

Niqel (Jatropha production and oil manufacturing) in Mozaqmbique operates the first industrial, fully mechanised, Jatropha oil mill in the world. The brand new factory is located on a 3 hectare plot in the center of the Niqel Jatropha estate. The incoming Jatropha fruits are turned into Jatropha bio-oil, green energy, Jatropha protein meal, organic pellets and organic fertilizer. The technology for the oil winning process was developed in the Netherlands. The Jatropha bio-oil presents a very promising alternative to diesel oil since it is renewable and has similar properties to the diesel. It can be used in conventional diesel engines without any engine modification, using a blend of 25% Jatropha bio-oil and 75% diesel.


Comments.
Jatropha lifecycle is unpredictable. latest information (2023) is that Niqel switched to the production of Eucalyptus

Who will be next.?

In a recent overview in Elsevier with the promising title "International experiences with the cultivation of Jatropha curcas for biodiesel production" https://www.sciencedirect.com/science/article/abs/pii/S0360544216308477 , the writer sums up a total of 22 jatropha disasters. Conclusion of the articele: After examining the global scenarios for the cultivation of J. curcas to produce biodiesel, the review concludes that the plant shows a large potential as an energy source to alleviate in part local environmental (e. g. recovering of waste land), social (e. g. employment demand) and economic (e. g. reduce poverty) problems.

About sustainability

And another one.
For more than seven years Diligent Energy systems was active in Tanzania. Diligent bought jatropha oil seeds from local farmers for a fair price and processed these seeds into biofuel. The oil was sold locally to flower farms safari companies and internationally for trials executed, among others, by KLM. The residue seed cake was used as an alternative for charcoal to, among others, safari companies who normally use firewood for their camps. Since the company was not able to become profitable, it was taken over by the DOEN foundation, a Dutch foundation operating with money from various lotteries. (30.000.000 Euro in 2013.)
Mission of the DOEN Foundation:
As driver of people and organizations that take the lead in the field of sustainable, social and cultural renewal DOEN Foundation strives towards a green, social and cultural society. DOEN supports these forerunners and brings them into contact with each other. DOEN Foundation annually supports more than 200 initiatives through grants, equity participations, loans and guarantees. Characteristic of these initiatives is the entrepreneurial approach: it is about people, organizations and companies that dare to take risks, be creative and innovative and thereby effectively contribute to a better and cleaner world. DOen supports initiatives in the field of culture and cohesion and green and social economy.
For unknown reasons DOEN decided to disinvest after a very short while, forcing the company into voluntary bankruptcy. At the very last minute the French based company Eco-Carbone decided to jump in to make Diligent profitable.
Statement of Eco-Carbone:
Eco-Carbone is very active in the new jatropha-based biofuel production market. It invests in several projects worldwide. Eco-Carbone provides technical advice to farmer communities who establish jatropha plantations. Eco-Carbone is both investor and manager of Industrial Joint Ventures, which produce crude oil and co-products of extraction.
Diligent could reach break even in 2014. There was money to buy at least 500 MT of jatropha seeds, there was pressing capacity to produce the oil and all the oil was already sold at forehand.

Unfortunately Eco-Carbone decided to desinvest, causing the end of Diligent Tanzania, leaving hundreds of farmers with unsold jatropha seeds.

Quinvita exit

There goes another one

The Jatropha breeding company Quinvita, (formerly D1) went into bankruptcy by the end of 2013. The breeding site on the Cape Verdian islands was closed down and planting material has been uprooted.

Combining Food and Fuel successfully


Trials with Jatropha curcas in combination with a foodcrop (in this case maize) have been successfully executed on three locations in Tanzania; Moshi, Bukoba and Mbinga.
