Constantly the biodiesel industry is looking for some alternative to produce renewable energy. Biodiesel prepared from canola, sunflower and jatropha can replace or be combined with . During very first half of 2000's jatropha curcas biofuel made the headlines as an incredibly popular and promising option. It is prepared from jatropha curcas, a plant species belonging to Central America that can be grown on wasteland.

Jatropha Curcas is a non edible plant that grows in the dry areas. The plant grows very rapidly and it can yield seeds for about 50 years. The oil received from its seeds can be utilized as a biofuel. This can be blended with petroleum diesel. Previously it has been utilized twice with algae mix to fuel test flight of airlines.

Another favorable approach of jatorpha seeds is that they have 37% oil content and they can be burned as a fuel without refining them. It is also used for medical purpose. Supporters of jatropha curcas biodiesel state that the flames of jatropha oil are smoke complimentary and they are successfully tested for simple diesel motor.

Jatropha biodiesel as Renewable resource Investment has actually drawn in the interest of many companies, which have checked it for automotive usage. jatropha curcas biodiesel has actually been roadway evaluated by Mercedes and three of the vehicles have covered 18,600 miles by using the jatropha plant biodiesel.

Since it is due to the fact that of some drawbacks, the jatropha biodiesel have actually ruled out as a fantastic renewable resource. The most significant problem is that nobody knows that exactly what the performance rate of the plant is. Secondly they don't know how large scale growing may impact the soil quality and the environment as a whole. The jatropha plant needs five times more water per energy than corn and sugarcane. This raises another issue. On the other hand it is to be noted that jatropha can grow on tropical environments with yearly rainfall of about 1000 to 1500 mm. A thing to be kept in mind is that jatropha requires proper watering in the first year of its plantation which lasts for years.

Recent study says that it is real that jatropha can grow on abject land with little water and poor nutrition. But there is no evidence for the yield to be high. This might be proportional to the quality of the soil. In such a case it might need high quality of land and may need the very same quagmire that is faced by most biofuel types.

Jatropha has one main disadvantage. The seeds and leaves of jatropha are poisonous to humans and livestock. This made the Australian federal government to ban the plant in 2006. The federal government stated the plant as intrusive types, and too dangerous for western Australian agriculture and the environment here (DAFWQ 2006).

While jatropha has promoting budding, there are number of research study challenges remain. The importance of detoxification needs to be studied because of the toxicity of the plant. Along side a systematic research study of the oil yield have to be undertaken, this is really important since of high yield of jatropha would most likely needed before jatropha can be contributed substantially to the world. Lastly it is also really important to study about the jatropha curcas types that can make it through in more temperature climate, as jatropha is quite restricted in the tropical environments.
