Constantly the biodiesel industry is searching for some option to produce renewable energy. Biodiesel prepared from canola, sunflower and jatropha can change or be integrated with traditional diesel. During first half of 2000's jatropha biofuel made the headlines as a preferred and promising alternative. 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 very rapidly and it can yield seeds for about 50 years. The oil obtained from its seeds can be used as a biofuel. This can be blended with petroleum diesel. Previously it has been utilized two times with algae mix to fuel test flight of airlines.

Another favorable method of jatorpha seeds is that they have 37% oil material and they can be burned as a fuel without refining them. It is also used for medical purpose. Supporters of jatropha biodiesel say that the flames of are smoke totally free and they are successfully evaluated for easy diesel motor.

Jatropha biodiesel as Renewable resource Investment has brought in the interest of many business, which have evaluated it for vehicle use. Jatropha biodiesel has actually been roadway tested by Mercedes and 3 of the cars have covered 18,600 miles by using the jatropha plant biodiesel.

Since it is because of some disadvantages, the jatropha biodiesel have not considered as a terrific renewable resource. The greatest issue is that no one knows that exactly what the performance rate of the plant is. Secondly they don't understand how large scale cultivation might impact the soil quality and the environment as a whole. The jatropha 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 can grow on tropical environments with annual rainfall of about 1000 to 1500 mm. A thing to be kept in mind is that jatropha requires correct irrigation in the very first year of its plantation which lasts for years.

Recent survey states that it is true 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 may be proportional to the quality of the soil. In such a case it might need high quality of land and might need the same quagmire that is faced by the majority of biofuel types.

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

While jatropha has stimulating budding, there are number of research difficulties stay. The importance of detoxification needs to be studied due to the fact that of the toxicity of the plant. Along side a methodical study of the oil yield have 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 extremely essential to study about the jatropha types that can survive in more temperature climate, as jatropha is very much limited in the tropical environments.
