Biodiesel is a fuel that it is made by vegetable oils and animal fat. It was invented by G.  Chavanne at 1937. Biodiesel is being used by many vehicles and industries, so it’s technology always needs to develop with the today’s technology. Biodiesel has been an important subject of debate since it was invented. Despite the widely claim that disadvantages of biodiesel it has economical and environmental advantages. Firstly, it has been asserted that production of biodiesel destroy tropical forest. Reinhardt, Rettenmaier and Gartner claim that “The latest example is the so-called ‘Mega Oil Project’ a forest conversion project 1.8 million ha. that was planned on border between Kalimantan(Borneo) and the neighboring Malaysian states of Sarawak and Sabah” (2007, p. 21). It is further claimed that LPG is more environmental friendly than normal fuels. On the other side, producing biodiesel does not need to more area to destroy tropical forest because present areas are sufficient to serve a need and also it helps to fight global warming. Moreover, today’s biodiesel technology is causing less CO emission than diesels.  Thwaites maintains that LPG is fossil fuel which green house added gas production by it (n.d. , p. 4). Considering a second argument commonly forwarded against biodiesel, it is causes starvation because biodiesel is produced by vegetables. It further asserted that biodiesel is produced by growing palm trees in rice farms. Some people claim that, research about biodiesel needs very high budgets because every new technology needs very large research and it causes to cost very high prices. It is true that growing palm trees in rice farms, however, Raymond states that lifetime of engines would be lengthen by applying oil of biodiesel (2006). Moreover biodiesel research do not cost high prices because biodiesel was founded by a ordinary person and he take its patent so research was studied his own possibilities. On the
