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 abject lands throughout 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 nearly everywhere. The consequences of the jatropha crash was polluted by accusations of land grabbing, mismanagement, and overblown carbon decrease claims.
Today, some scientists continue pursuing the evasive pledge of high-yielding jatropha. A return, they state, is dependent on cracking the yield problem and resolving the damaging land-use problems intertwined with its original failure.
The sole staying big jatropha plantation remains in Ghana. The plantation owner declares high-yield domesticated ranges have actually been accomplished and a brand-new boom is at hand. But even if this return fails, the world's experience of jatropha holds important lessons for any appealing up-and-coming biofuel.
At the start 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 pledge as a sustainable source of biofuel that might be grown on degraded, unfertile lands so as not to displace food crops. But inflated claims of high yields failed.
Now, after years of research and advancement, the sole staying large plantation focused on growing jatropha is in Ghana. And Singapore-based jOil, which owns that plantation, declares the jatropha comeback is on.
"All those business that stopped working, embraced a plug-and-play design of hunting for the wild varieties of jatropha. But to commercialize it, you need to domesticate it. This belongs of the procedure that was missed out on [during the boom]," jOil CEO Vasanth Subramanian told Mongabay in an interview.
Having gained from the mistakes of jatropha's past failures, he says the oily plant could yet play a crucial function as a liquid biofuel feedstock, minimizing transportation carbon emissions at the global level. A new boom might bring additional advantages, with jatropha likewise a potential source of fertilizers and even bioplastics.
But some scientists are hesitant, keeping in mind that jatropha has already gone through one hype-and-fizzle cycle. They caution that if the plant is to reach full capacity, then it is necessary to discover from past mistakes. During the first boom, jatropha curcas plantations were obstructed not only by bad yields, but by land grabbing, deforestation, and social issues in countries where it was planted, consisting of Ghana, where jOil runs.
Experts also recommend that jatropha's tale provides lessons for researchers and entrepreneurs exploring 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 lawns, trees and other plants not derived from edible crops such as maize, soy or oil palm. Among its multiple purported virtues was an ability to prosper on abject or "limited" lands
