Driving forces for biodiesel

The key driving forces for biodiesel are the directive for the promotion of biofuels and the directive on fuel quality. The former is motivated by the need to cut greenhouse gas emissions in the transport sector and increase energy security by reducing dependence on imported oil. Also encouraging the growth of biodiesel are useful properties such as less local air pollution, rapid biodegradability, low toxicity to people and the environment, and high flashpoint. The supply of biodiesel is limited, however, by the availability of oilseed crops. Any plan for biodiesel should begin with a careful study of existing experience, followed by a survey of feedstock options including recycled cooking oil.
