The new market that uses renewable fuel is favorable to the environment and open doors for small farmers. But it is still necessary to balance between risks and opportunities.After had provoked a energetic revolution when constructed a process to transform sugar cane in ethanol, Brazil is having the change to repeat this accomplish with Biodiesel. This new renewable fuel shares qualities with ethanol just starting from the environment benefits.Used in substitution of the petroleum’s derivatives, as much ethanol as biodiesel convert themselves in capable tools of delay global warming, reducing billions of tons of carbon dioxide throw in the atmosphere every year.The biodiesel’s advantage starts being more democratic to small farmers. Besides that, products already established in the Brazilian agro business, like cotton and soy, can live with new growth like pinhao-manso. That’s the main difference between biodiesel and ethanol: the multiplicity of raw material.The green fuel’s challenge is to elevate its productive chain as efficient as ethanol’s. There is enough market for both. In a world that demands each time more clean energy, there’s no competition between renewable energy.
