New regulations have provided for almost zero sulfur dioxide content in biodiesels. Environmentally this fuel has proven to be a much less pollutant than its counterpart, the standard diesel.
One of the concerns has to do with the conversion to biodiesel, the timing and costs associated with this conversion are still not clear. The fuel has similar properties as that of the diesel, making it easy to use. In the process they discovered that just about any kind of vegetable or animal oil that we use to cook with today can be processed into biodiesel fuel.
Water accelerates microbe colonies which shorten the life cycle of the paper filter elements that result in premature failure of the fuel pump. In view of the fact that biodiesel does not contain sulphur and aromatics, it burns cleaner leaving very few traces of contaminants. Biodiesel use results in a significantly reduced emission of carbon monoxide.
The challenge we face is to educate the public about the issues surrounding biofuels and what is good or bad. Instead of destroying forests maybe we should look to new more green raw materials for producing biofuels.
