Constantly the biodiesel industry is looking for some option to produce renewable resource. Biodiesel prepared from canola, sunflower and jatropha curcas can replace or be integrated with conventional diesel. During first half of 2000's jatropha biofuel made the headings as a very popular and promising option. It is prepared from jatropha curcas, a plant types 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 rapidly and it can yield seeds for about 50 years. The oil got from its seeds can be utilized as a biofuel. This can be blended with petroleum diesel. Previously it has been used two times with algae combination to fuel test flight of airlines.

Another positive method 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 biodiesel say that the flames of jatropha oil are smoke complimentary and they are successfully tested for easy diesel engines.

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

Since it is because of some downsides, the jatropha biodiesel have not considered as a wonderful sustainable energy. The biggest problem is that no one understands that what precisely the productivity rate of the plant is. Secondly they don't know how big scale growing may affect the soil quality and the environment as a whole. The jatropha curcas plant needs 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 correct watering in the first year of its plantation which lasts for years.

Recent study says that it is true that jatropha can grow on degraded land with little water and bad 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 may need high quality of land and might need the same quagmire that is faced by the majority of biofuel types.

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

While jatropha curcas has stimulating budding, there are number of research study challenges remain. The importance of detoxification has to be studied since of the toxicity of the plant. Along side a methodical research study of the oil yield need to be carried out, this is extremely essential since of high yield of jatropha would probably needed before jatropha can be contributed considerably to the world. Lastly it is also very essential to study about the jatropha species that can endure in more temperature climate, as jatropha is quite limited in the tropical environments.
