Constantly the biodiesel industry is searching for some alternative to produce sustainable energy. Biodiesel prepared from canola, sunflower and jatropha can replace or be combined with standard diesel. During first half of 2000's jatropha curcas biofuel made the headlines as a preferred and appealing option. It is prepared from jatropha curcas, a plant species native to Central America that can be grown on wasteland.

Jatropha Curcas is a non edible plant that grows in the deserts. The plant grows extremely quickly and it can yield seeds for about 50 years. The oil obtained from its seeds can be utilized as a biofuel. This can be mixed with petroleum diesel. Previously it has been used two times with algae mix to sustain test flight of commercial airlines.

Another positive approach of jatorpha seeds is that they have 37% oil material and they can be burned as a fuel without fine-tuning them. It is likewise used for medical purpose. Supporters of jatropha biodiesel state that the flames of jatropha oil are smoke complimentary and they are successfully evaluated for simple diesel motor.

Jatropha biodiesel as Renewable Energy Investment has attracted the interest of many business, which have checked it for automotive use. Jatropha biodiesel has been roadway tested by Mercedes and three of the cars and trucks have covered 18,600 miles by using the jatropha plant biodiesel.

Since it is because of some downsides, the jatropha biodiesel have ruled out as a terrific sustainable energy. The most significant issue is that no one understands that what exactly the productivity rate of the plant is. Secondly they don't know how big scale cultivation might affect the soil quality and the environment as a whole. The jatropha curcas plant requires 5 times more water per energy than corn and sugarcane. This raises another concern. On the other hand it is to be noted that jatropha curcas can grow on tropical environments with annual rainfall of about 1000 to 1500 mm. A thing to be noted is that jatropha needs proper watering in the first year of its plantation which lasts for decades.

Recent survey states that it holds true that jatropha can grow on degraded land with little water and poor nutrition. But there is no evidence for the yield to be high. This may be proportional to the quality of the soil. In such a case it might require high quality of land and may require the exact same quagmire that is faced by the majority of biofuel types.

Jatropha has one main drawback. The seeds and leaves of jatropha are toxic to people and animals. This made the Australian government to prohibit the plant in 2006. The government stated the plant as invasive species, and too dangerous for western Australian farming and the environment here (DAFWQ 2006).

While jatropha has promoting budding, there are variety of research difficulties remain. The significance of detoxing has to be studied due to the fact that of the toxicity of the plant. Along side an organized study of the oil yield need to be undertaken, this is very important due to the fact that of high yield of jatropha would probably required before jatropha can be contributed substantially to the world. Lastly it is also really essential to study about the jatropha curcas types that can survive in more temperature environment, as jatropha is very much limited in the tropical climates.
