Earlier this century, jatropha was hailed as a "wonder" biofuel. A simple shrubby tree belonging to Central America, it was hugely promoted as a high-yielding, drought-tolerant biofuel feedstock that might grow on degraded lands throughout 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 led to plantation failures almost all over. The after-effects of the jatropha crash was polluted by accusations of land grabbing, mismanagement, and overblown carbon decrease claims.
Today, some researchers continue pursuing the evasive promise of high-yielding jatropha. A resurgence, they state, depends on cracking the yield issue and dealing with the harmful land-use issues 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 attained 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 promising 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 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 and development, the sole staying large plantation focused 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 hunting for the wild varieties of jatropha. But to commercialize it, you require to domesticate it. This is a part of the process that was missed out on [throughout the boom]," jOil CEO Vasanth Subramanian informed Mongabay in an interview.
Having gained from the mistakes of jatropha's past failures, he states the oily plant might yet play an essential role as a liquid biofuel feedstock, minimizing transportation carbon emissions at the worldwide level. A new boom could bring additional benefits, with jatropha also a prospective source of fertilizers and even bioplastics.
But some scientists are hesitant, noting that jatropha has actually currently gone through one hype-and-fizzle cycle. They warn that if the plant is to reach complete potential, then it is necessary to discover from past mistakes. During the very first boom, jatropha plantations were hindered not just by bad yields, however by land grabbing, deforestation, and social issues in nations where it was planted, consisting of Ghana, where jOil runs.
Experts likewise suggest that jatropha's tale offers lessons for researchers and entrepreneurs checking out promising new sources for liquid biofuels - which exist aplenty.
Miracle shrub, significant bust
Jatropha's early 21st-century appeal originated from its pledge as a "second-generation" biofuel, which are sourced from lawns, trees and other plants not obtained from edible crops such as maize, soy or oil palm. Among its numerous purported virtues was an ability to flourish on abject or "minimal" lands
