Biodiesel fuels are one product that the green market offers that works to lower carbon dioxide and other dangerous chemicals from the atmosphere. Biodiesel fuels are taken from renewable sources such as soybeans and other agricultural byproducts. They are biodegradable, through a process called transesterification, where the glycerin is separated from the fats. The oils and grease from these bio sources are then converted into fuel, which can be used alone or as extenders in other fuels.
Thanks to the National Renewable Energy Laboratory (NREL), there is solid evidence that bio fuels are the way to go and are enough to help combat the pollution crisis. The NREL conducted a study regarding the use of biodiesel fuels on a fleet of heavy duty diesel trucks. The study was aimed to determine the effect that biodiesel and biodiesel blends have on the emissions from these trucks. In essence, the study found that risk of premature deaths due to exposure from air toxins is reduced by 2-5%, and the amount of particulate matter was reduced by 4-7%.
Although the effects of biodiesel fuel on air quality have not been quantified by the EPA or other institutions, it is clear is there is an advantage to using bio fuels. When used with diesel engines, the emissions improve ignition and oxidant distribution, thus improving overall emissions. Dangerous hydrocarbons and particulate matter have an inherent toxicity. Because biodiesel reduces the toxicity of particulate matter, it's important to explore this potential option for lowering health issues
