Constantly the biodiesel market is looking for some alternative to produce sustainable energy. Biodiesel prepared from canola, sunflower and jatropha can change or be combined with conventional diesel. During very first half of 2000's jatropha biofuel made the headings as a popular and appealing alternative. 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 arid regions. The plant grows extremely rapidly and it can yield seeds for about 50 years. The oil got from its seeds can be used as a biofuel. This can be combined with petroleum diesel. Previously it has been used twice with algae combination to flight of airlines.

Another favorable approach of jatorpha seeds is that they have 37% oil material and they can be burned as a fuel without improving them. It is also used for medical function. Supporters of jatropha biodiesel say that the flames of jatropha oil are smoke complimentary and they are successfully checked for easy diesel motor.

jatropha curcas biodiesel as Renewable resource Investment has brought in the interest of many companies, which have actually tested it for automobile usage. Jatropha biodiesel has been roadway evaluated by Mercedes and three of the cars and trucks have actually covered 18,600 miles by utilizing the jatropha plant biodiesel.

Since it is since of some drawbacks, the jatropha biodiesel have actually ruled out as a wonderful renewable resource. The biggest issue is that nobody understands that what precisely the productivity rate of the plant is. Secondly they do not understand how large scale growing might affect the soil quality and the environment as a whole. The jatropha plant requires five 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 climates with annual rainfall of about 1000 to 1500 mm. A thing to be kept in mind is that jatropha requires correct watering in the very 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 may require high quality of land and may need the same quagmire that is dealt with by most biofuel types.

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

While jatropha has promoting budding, there are number of research challenges remain. The value of detoxification has to be studied since of the toxicity of the plant. Along side an organized research study of the oil yield need to be carried out, this is really important since of high yield of jatropha would probably required before jatropha curcas can be contributed substantially to the world. Lastly it is also really important to study about the jatropha curcas types that can endure in more temperature climate, as jatropha curcas is very much limited in the tropical environments.
