Earlier this century, jatropha was hailed as a "miracle" biofuel. An unassuming shrubby tree belonging to Central America, it was extremely promoted as a high-yielding, drought-tolerant biofuel feedstock that could grow on degraded lands throughout 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 resulted in plantation failures nearly everywhere. The after-effects of the jatropha crash was tainted by allegations of land grabbing, mismanagement, and overblown carbon decrease claims.
Today, some researchers continue pursuing the incredibly elusive guarantee of high-yielding jatropha. A return, they say, depends on breaking the yield issue and addressing the hazardous land-use issues intertwined with its original failure.
The sole remaining big jatropha plantation remains in Ghana. The plantation owner declares high-yield domesticated ranges have actually been accomplished and a new boom is at hand. But even if this comeback falters, the world's experience of jatropha holds crucial lessons for any promising up-and-coming biofuel.
At the beginning of the 21st century, Jatropha curcas, an unassuming shrub-like tree belonging 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 deteriorated, unfertile lands so as not to displace food crops. But inflated claims of high yields fell flat.
Now, after years of research study and development, the sole staying big plantation focused on growing jatropha remains in Ghana. And Singapore-based jOil, which owns that plantation, declares the jatropha comeback is on.
"All those business that failed, adopted a plug-and-play design of scouting for the wild varieties of jatropha. But to commercialize it, you need to domesticate it. This is a part of the procedure that was missed out on [throughout the boom]," jOil CEO Vasanth Subramanian informed Mongabay in an interview.
Having gained from the errors of jatropha's past failures, he states the oily plant could yet play an essential function as a liquid biofuel feedstock, lowering transportation carbon emissions at the international level. A brand-new boom could bring fringe benefits, with jatropha likewise a possible source of fertilizers and even bioplastics.
But some researchers are hesitant, noting that jatropha has actually already gone through one hype-and-fizzle cycle. They warn that if the plant is to reach complete capacity, then it is important to gain from previous errors. During the first boom, jatropha plantations were obstructed not just by poor yields, however by land grabbing, deforestation, and social issues in countries where it was planted, including Ghana, where jOil runs.
Experts likewise recommend that jatropha's tale provides lessons for researchers and business owners checking out promising brand-new sources for liquid biofuels - which exist aplenty.
Miracle shrub, significant bust
Jatropha's early 21st-century appeal came from its promise as a "second-generation" biofuel, which are sourced from yards, trees and other plants not stemmed from edible crops such as maize, soy or oil palm. Among its several purported virtues was a capability to grow on abject or "minimal" lands
