1 Jatropha: the Biofuel that Bombed Seeks a Path To Redemption

Earlier this century, jatropha was hailed as a "wonder" biofuel. A simple shrubby tree native to Central America, it was wildly promoted as a high-yielding, drought-tolerant biofuel feedstock that could grow on degraded lands across 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 caused plantation failures almost 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 evasive guarantee of high-yielding jatropha. A comeback, they state, is dependent on breaking the yield problem and attending to the damaging land-use problems intertwined with its initial failure.
The sole staying big jatropha plantation is in Ghana. The plantation owner claims high-yield domesticated ranges have actually been accomplished and a new boom is at hand. But even if this return falters, the world's experience of jatropha holds important lessons for any promising up-and-coming biofuel.
At the beginning 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 guarantee as a sustainable source of biofuel that might 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 advancement, the sole staying 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 business that failed, embraced a plug-and-play design of hunting for the wild ranges of jatropha. But to advertise 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 a key function as a liquid biofuel feedstock, decreasing transport carbon emissions at the worldwide level. A new boom might bring extra advantages, with jatropha likewise a possible source of fertilizers and even bioplastics.

But some scientists are doubtful, keeping in mind that jatropha has actually currently gone through one hype-and-fizzle cycle. They caution that if the plant is to reach complete potential, then it is essential to find out from past errors. During the very first boom, jatropha plantations were hindered 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 offers lessons for scientists and entrepreneurs checking out appealing brand-new sources for liquid biofuels - which exist aplenty.

Miracle shrub, major bust

Jatropha's early 21st-century appeal stemmed from its guarantee as a "second-generation" biofuel, which are sourced from lawns, trees and other plants not originated from edible crops such as maize, soy or oil palm. Among its multiple supposed virtues was an ability to prosper on degraded or "marginal" lands
