Earlier this century, jatropha was hailed as a "miracle" biofuel. An unassuming shrubby tree native to Central America, it was extremely 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 resulted in plantation failures nearly everywhere. The consequences of the jatropha crash was tainted by accusations of land grabbing, mismanagement, and overblown carbon decrease claims.
Today, some scientists continue pursuing the incredibly elusive guarantee of high-yielding jatropha. A resurgence, they say, is dependent on splitting the yield problem and resolving the hazardous land-use problems intertwined with its original failure.
The sole remaining large jatropha plantation is in Ghana. The plantation owner declares high-yield domesticated ranges have been attained and a new boom is at hand. But even if this return 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 throughout 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 and advancement, 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, adopted a plug-and-play model of scouting for the wild ranges of jatropha. But to commercialize it, you require to domesticate it. This belongs of the process that was missed [during the boom]," jOil CEO Vasanth Subramanian informed Mongabay in an interview.
Having gained from the mistakes of jatropha's previous failures, he states the oily plant could yet play an essential function as a liquid biofuel feedstock, minimizing transport carbon emissions at the global level. A brand-new boom might bring additional benefits, with jatropha also a potential source of fertilizers and even bioplastics.
But some scientists are skeptical, noting that jatropha has actually already gone through one . They warn that if the plant is to reach complete potential, then it is important to gain from previous errors. During the first boom, jatropha plantations were obstructed not only by poor yields, however by land grabbing, deforestation, and social issues in nations where it was planted, including Ghana, where jOil operates.
Experts likewise suggest that jatropha's tale provides lessons for scientists and entrepreneurs checking out promising 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 originated from edible crops such as maize, soy or oil palm. Among its several supposed virtues was an ability to prosper on degraded or "limited" lands
