Earlier this century, jatropha was hailed as a "wonder" biofuel. A simple shrubby tree belonging to Central America, it was hugely promoted as a high-yielding, drought-tolerant biofuel feedstock that might grow on abject lands across Latin America, Africa and Asia.
A jatropha rush occurred, with more than 900,000 hectares (2.2 million acres) planted by 2008. But the bubble burst. Low yields caused plantation failures almost all over. The consequences of the jatropha crash was tainted by accusations of land grabbing, mismanagement, and overblown carbon reduction claims.
Today, some researchers continue pursuing the evasive guarantee of high-yielding jatropha. A return, they state, depends on breaking the yield issue and attending to the damaging land-use problems linked with its original failure.
The sole remaining large jatropha plantation is in Ghana. The plantation owner declares high-yield domesticated ranges have actually been attained and a brand-new boom is at hand. But even if this resurgence falters, the world's experience of jatropha holds essential lessons for any promising up-and-coming biofuel.
At the beginning of the 21st century, Jatropha curcas, a simple shrub-like tree belonging to Central America, was planted across the world. The rush to jatropha was driven by its pledge as a sustainable source of biofuel that could be grown on deteriorated, unfertile lands so as not to displace food crops. But inflated claims of high yields failed.
Now, after years of research study and development, the sole remaining big plantation concentrated on growing jatropha is in Ghana. And Singapore-based jOil, which owns that plantation, declares the jatropha resurgence is on.
"All those companies that stopped working, embraced a plug-and-play design of scouting for the wild varieties of jatropha. But to advertise it, you need to domesticate it. This belongs of the procedure that was missed [during the boom]," jOil CEO Vasanth Subramanian told Mongabay in an interview.
Having gained from the errors of jatropha's past failures, he states the oily plant might yet play a crucial function as a liquid biofuel feedstock, reducing transportation carbon emissions at the worldwide level. A new boom could bring extra benefits, with jatropha also a prospective source of fertilizers and even bioplastics.
But some scientists are doubtful, noting that jatropha has actually already gone through one hype-and-fizzle cycle. They warn that if the plant is to reach full capacity, then it is necessary to learn from previous mistakes. During the first boom, jatropha plantations were hampered not just by poor yields, however by land grabbing, logging, and social problems in nations where it was planted, consisting of Ghana, where jOil runs.
Experts likewise recommend that jatropha's tale offers lessons for scientists and business owners checking out appealing brand-new sources for liquid biofuels - which exist aplenty.
Miracle shrub, major bust
Jatropha's early 21st-century appeal came from its promise as a "second-generation" biofuel, which are sourced from grasses, trees and other plants not derived from edible crops such as maize, soy or oil palm. Among its numerous supposed virtues was an ability to thrive on degraded or "marginal" lands
