Earlier this century, jatropha was hailed as a "wonder" biofuel. A simple shrubby tree belonging to Central America, it was wildly promoted as a high-yielding, drought-tolerant biofuel feedstock that might grow on abject lands across Latin America, Africa and Asia.
A jatropha rush took place, 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 polluted by accusations of land grabbing, mismanagement, and overblown carbon reduction claims.
Today, some researchers continue pursuing the evasive promise of high-yielding jatropha. A resurgence, they say, is reliant on breaking the yield issue and attending to the harmful land-use concerns intertwined with its initial failure.
The sole remaining big jatropha plantation is in Ghana. The plantation owner declares high-yield domesticated ranges have actually been achieved and a brand-new boom is at hand. But even if this return falters, the world's experience of jatropha holds crucial lessons for any appealing up-and-coming biofuel.
At the beginning of the 21st century, Jatropha curcas, a simple shrub-like tree native to Central America, was planted throughout the world. The rush to jatropha was driven by its promise as a sustainable source of biofuel that might be grown on broken down, unfertile lands so as not to displace food crops. But inflated claims of high yields fell flat.
Now, after years of research study and advancement, the sole staying big plantation focused on growing jatropha remains in Ghana. And Singapore-based jOil, which owns that plantation, claims the jatropha return is on.
"All those companies that stopped working, embraced a plug-and-play model of scouting for the wild ranges of jatropha. But to commercialize it, you need to domesticate it. This is a part of the procedure that was missed out on [during the boom]," jOil CEO Vasanth Subramanian informed Mongabay in an interview.
Having found out from the errors of jatropha's past failures, he states the oily plant might yet play a key function as a liquid biofuel feedstock, minimizing transport carbon emissions at the worldwide level. A new boom could bring fringe benefits, with jatropha also a potential source of fertilizers and even bioplastics.
But some scientists are doubtful, noting that jatropha has already gone through one hype-and-fizzle cycle. They caution that if the plant is to reach complete potential, then it is vital to find out from past errors. During the very first boom, jatropha plantations were obstructed not just by bad yields, however by land grabbing, logging, and social problems in nations where it was planted, consisting of Ghana, where jOil operates.
Experts likewise suggest that jatropha's tale offers lessons for scientists and business owners exploring promising 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 turfs, trees and other plants not obtained from edible crops such as maize, soy or oil palm. Among its several purported virtues was a capability to thrive on abject or "limited" lands
