Constantly the biodiesel market is trying to find some alternative 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 preferred and promising alternative. 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 arid regions. The plant grows very rapidly and it can yield seeds for about 50 years. The oil obtained from its seeds can be utilized as a biofuel. This can be mixed with petroleum diesel. Previously it has been used twice with algae combination to fuel test flight of airlines.

Another favorable technique 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 state that the flames of jatropha oil are smoke free and they are successfully evaluated for basic diesel engines.

jatropha curcas biodiesel as Renewable Energy Investment has actually brought in the interest of lots of companies, which have checked it for automotive usage. Jatropha biodiesel has been roadway evaluated by Mercedes and three of the automobiles have actually covered 18,600 miles by utilizing the jatropha curcas plant biodiesel.

Since it is since of some drawbacks, the jatropha curcas biodiesel have actually not thought about as a fantastic renewable resource. The biggest problem is that no one understands that just what the performance rate of the plant is. Secondly they do not know how large scale cultivation might impact 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 kept in mind that jatropha can grow on tropical environments with yearly rains of about 1000 to 1500 mm. A thing to be noted is that jatropha requires appropriate irrigation in the very first year of its plantation which lasts for decades.

Recent study states that it holds true that jatropha can grow on abject land with little water and poor nutrition. But there is no proof 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 may need the same quagmire that is dealt with by many biofuel types.

jatropha curcas has one main downside. The seeds and leaves of jatropha are poisonous to people and animals. This made the Australian government to prohibit the plant in 2006. The stated the plant as invasive species, and too risky for western Australian farming and the environment here (DAFWQ 2006).

While jatropha curcas has stimulating budding, there are number of research study obstacles remain. The importance of cleansing has to be studied since of the toxicity of the plant. Along side a systematic research study of the oil yield have to be carried out, this is very important because of high yield of jatropha curcas would most likely required before jatropha curcas can be contributed considerably to the world. Lastly it is also very important to study about the jatropha species that can make it through in more temperature level environment, as jatropha is quite limited in the tropical climates.
