Constantly the biodiesel industry is searching for some alternative to produce renewable resource. Biodiesel prepared from canola, sunflower and jatropha can replace or be combined with standard diesel. During first half of 2000's jatropha biofuel made the headlines as an extremely popular 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 really rapidly and it can yield seeds for about 50 years. The oil received from its seeds can be used as a biofuel. This can be blended with petroleum diesel. Previously it has been used twice with algae combination to fuel test flight of airlines.

Another positive 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 curcas biodiesel state that the flames of jatropha oil are smoke complimentary and they are successfully evaluated for simple diesel motor.

jatropha curcas biodiesel as Renewable Energy Investment has brought in the interest of numerous business, which have actually checked it for automobile use. Jatropha biodiesel has actually been roadway tested by Mercedes and three of the automobiles have actually covered 18,600 miles by utilizing the jatropha plant biodiesel.

Since it is since of some downsides, the jatropha biodiesel have not considered as a wonderful eco-friendly energy. The most significant problem is that nobody understands that exactly what the productivity rate of the plant is. Secondly they do not understand how large scale growing may 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 issue. On the other hand it is to be kept in mind that jatropha curcas can grow on tropical climates with annual rainfall of about 1000 to 1500 mm. A thing to be noted is that jatropha curcas needs appropriate watering in the first year of its plantation which lasts for years.

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

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

While jatropha has stimulating budding, there are number of research study challenges stay. The value of detoxification needs to be studied due to the fact that of the toxicity of the plant. Along side a systematic research study of the oil yield need to be undertaken, this is very essential due to the fact that of high yield of jatropha curcas would probably needed before jatropha curcas can be contributed considerably to the world. Lastly it is also very essential to study about the jatropha species that can survive in more temperature climate, as jatropha is quite limited in the tropical climates.
