Constantly the biodiesel industry is looking for some option to produce renewable energy. Biodiesel prepared from canola, sunflower and jatropha can change or be integrated with standard diesel. During very first half of 2000's jatropha curcas biofuel made the headings as an incredibly popular 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 extremely rapidly and it can yield seeds for about 50 years. The oil obtained from its seeds can be used as a . This can be combined with petroleum diesel. Previously it has been used twice with algae mix to sustain 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 used for medical purpose. Supporters of jatropha biodiesel state that the flames of jatropha oil are smoke totally free and they are effectively tested for easy diesel motor.

Jatropha biodiesel as Renewable Energy Investment has actually attracted the interest of lots of companies, which have evaluated it for automotive use. Jatropha biodiesel has been roadway checked by Mercedes and 3 of the cars have covered 18,600 miles by using the jatropha curcas plant biodiesel.

Since it is since of some disadvantages, the jatropha curcas biodiesel have actually not considered as a wonderful renewable resource. The most significant problem is that nobody knows that what exactly the efficiency rate of the plant is. Secondly they do not know how large scale cultivation may impact the soil quality and the environment as a whole. The jatropha 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 climates with yearly rainfall of about 1000 to 1500 mm. A thing to be noted is that jatropha needs correct watering in the very first year of its plantation which lasts for years.

Recent study says that it is true that jatropha curcas can grow on degraded land with little water and poor 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 very same quagmire that is faced by the majority of biofuel types.

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

While jatropha has promoting budding, there are number of research challenges stay. The importance of cleansing needs 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 extremely important because of high yield of jatropha would probably needed before jatropha curcas can be contributed significantly to the world. Lastly it is also extremely crucial to study about the jatropha species that can survive in more temperature environment, as jatropha is very much limited in the tropical environments.
