Constantly the biodiesel industry is searching for some alternative to produce renewable resource. Biodiesel prepared from canola, sunflower and jatropha can change or be combined with traditional diesel. During very first half of 2000's jatropha biofuel made the headlines as a preferred and appealing 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 very 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 combined with petroleum diesel. Previously it has been used two times with algae combination to sustain test flight of commercial airlines.

Another positive technique of jatorpha seeds is that they have 37% oil material and they can be burned as a fuel without improving them. It is also utilized for medical purpose. Supporters of jatropha curcas biodiesel say that the flames of jatropha curcas oil are smoke complimentary and they are successfully checked for easy diesel engines.

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

Since it is because of some downsides, the jatropha biodiesel have ruled out as a wonderful sustainable energy. The most significant issue is that no one knows that what precisely the efficiency rate of the plant is. Secondly they don't understand how big may impact the soil quality and the environment as a whole. The jatropha plant needs five times more water per energy than corn and sugarcane. This raises another issue. On the other hand it is to be noted that jatropha can grow on tropical climates with yearly rains of about 1000 to 1500 mm. A thing to be kept in mind is that jatropha requires appropriate irrigation in the first year of its plantation which lasts for years.

Recent survey states that it is true that jatropha curcas 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 same quagmire that is dealt with by a lot of biofuel types.

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

While jatropha curcas has stimulating budding, there are variety of research challenges remain. The importance of detoxing needs to be studied due to the fact that of the toxicity of the plant. Along side an organized study of the oil yield have actually to be undertaken, this is very important since of high yield of jatropha would most likely needed before jatropha can be contributed considerably to the world. Lastly it is also extremely crucial to study about the jatropha curcas types that can survive in more temperature environment, as jatropha is quite limited in the tropical climates.
