The awareness for the consequences of the emission of the greenhouse gases and the international increase of the oil price, gave place to a global chase for biofuels as a similar substitute of the imported oil products. According with the International Energy Agency data, it’s estimated that the world consumption will rise to the 70 million “tons” in 2020 and 130 million “tons” in 2030. Nevertheless, for the environment and the safe energy supply benefits to become real, it is critical to develop a sustainable agriculture culture, making sure the forests, lands and food crops will not be compromised. Indeed, the impact of the biofuels over the environment, must be measured horizontally – well to wheel – and should consider alternative uses for the already (and most of the time) worn out lands, the amount of energy needed to farm a land, the transformation and transportation costs of the raw material to the production factories and the degree of efficiency of the energetic crops. Since the biofuels are the engine for rural development and job increase, we must make sure, from the beginning, that the industrial and technological approach, promotes the production competitiveness in the international markets. The EXERGIA group is laying hopes on a bush, called Jatropha curcas,

Jatropha is a shrub - 2 to 4 feet tall - that grows in semi-arid grounds, needing no more than 1,000 mm of rain per year. The reduced amount of water needed for survival may make it an important plant in combating desertification, complemented by being largely resistant to pests and have a lifespan between 30 and 50 years.
