Biodiesel is one of the most widely used bio fuels along with bio-ethanol.
It's based on bean and canola oils, and poses no harm to the environment.
Korea was Asia's first to launch the commercialization of biodiesel in 2006.
Research into the environmental impact of biodiesel continues to this day.
The National Institute of Environmental Research has compared several materials used in biodiesel.
The results showed that the higher the percentage of vegetable oil, the less volatile organic compounds were found in diesel.
In other words, regular diesel containing a high percentage of biodiesel emits less environmental pollutants.
Cars fueled entirely by regular diesel were found to pollute the environment more than cars fueled by diesel mixed with biodiesel.
[Interview : Lim Cheol-soo, Scientist
National Institute of Environmental Research] "Biodiesel has better lubricity than regular diesel and burns better because it contains more oxygen. That's why it makes it possible to reduce emissions of carbon monoxide, hydrocarbon and dust."
This biodiesel manufacturer in Siheung, Gyeonggi Province has developed its own technologies.
Biodiesel produced here is based on bean oil, waste cooking oil and methanol.
[Interview : Han Gu-jae, President
Dansuk Industrial Company] "Places that provide meals for big groups like the army have large amounts of used cooking oil. We make biodiesel using the waste oil which is a nature-friendly resource."
As materials used in biodiesel continue to stir a controversy, the development of biodiesel based on non-edible crops is urgent.
This company has been developing biodiesel using jatropha and energy-efficient shiny-leaf yellow horn, which contains 98 percent oil.
Diesel sold currently at gas stations contains 1.5 by
