Constantly the biodiesel industry is searching for some option to produce sustainable energy. Biodiesel prepared from canola, sunflower and jatropha can replace or be combined with conventional diesel. During first half of 2000’s jatropha curcas biofuel made the headlines as an extremely popular and promising alternative. It is prepared from jatropha curcas, a plant types belonging 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 quickly and it can yield seeds for about 50 years. The oil received from its seeds can be used as a biofuel. This can be combined with petroleum diesel. Previously it has been utilized two times with algae mix to fuel test flight of airlines.

Another positive technique of jatorpha seeds is that they have 37% oil content and they can be burned as a fuel without fine-tuning them. It is likewise utilized for medical purpose. Supporters of jatropha biodiesel state that the flames of jatropha curcas oil are smoke totally free and they are successfully evaluated for basic diesel motor.

jatropha curcas biodiesel as Renewable Energy Investment has actually drawn in the interest of lots of business, which have actually evaluated it for automotive use. Jatropha biodiesel has actually been road tested by Mercedes and 3 of the cars have covered 18,600 miles by utilizing the jatropha curcas plant biodiesel.

Since it is due to the fact that of some disadvantages, the jatropha biodiesel have actually not considered as a terrific renewable energy. The greatest problem is that no one knows that what precisely the performance rate of the plant is. Secondly they don’t know how large scale cultivation 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 can grow on tropical environments with annual rainfall of about 1000 to 1500 mm. A thing to be kept in mind is that jatropha needs appropriate irrigation in the first year of its plantation which lasts for years.

Recent survey says that it holds 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 may be proportional to the quality of the soil. In such a case it may need high quality of land and might need the very same quagmire that is dealt with by many biofuel types.

jatropha curcas has one primary drawback. The seeds and leaves of jatropha curcas are hazardous to people and animals. This made the Australian government to prohibit the plant in 2006. The government declared the plant as intrusive species, and too risky for agriculture and the environment here (DAFWQ 2006).

While jatropha has promoting budding, there are number of research challenges remain. The value of detoxification needs to be studied because of the toxicity of the plant. Along side an organized study of the oil yield need to be undertaken, this is extremely essential because of high yield of jatropha would most likely required before jatropha curcas can be contributed significantly to the world. Lastly it is also very crucial to study about the jatropha species that can endure in more temperature climate, as jatropha is extremely much restricted in the tropical climates.
