Biodiesel is made from renewable resources such as vegetable oils, animal fats or cast-off greases. It is a renewable diesel operating like the traditional diesel. Biodiesel can be used in its untainted structure as a fuel for vehicles, but usually it is used as a diesel stabilizer in diesel-powered vehicles, which helps to diminish the levels of carbon monoxide, particulates and hydrocarbons. Biodiesel can be used single-handedly or can be combined with petrodiesel. In United States it’s regulated as mono-alkyl ester.
Environmental upshots - In contemporary world where petrol has reached excessive prices and is diminishing in quantity, moreover causing harms to the environment; people are in search of substitutes which would solve their all above revealed problems. There are subsequent environmental benefits when choosing to use biodiesel over standard petroleum based diesel. They are as follows:
Reduces Pollution - Biodiesel lessens almost all forms of pollutants like carbon oxides, nitrogen oxides, carbon oxides, etc which contributes to air pollution. Biodiesel contains higher cetane rating than petrodiesel, which can help in improving the performance and crackdown emissions as compared to unrefined petro-diesel. Fossil fuels on other hand burns sulfur dioxide (SO2) and other elements that source the air to become polluted. Biodiesel use thus could provide reductions in several air pollutants, which could lead to significant improvements in cities where air quality is a concern.
Reduces Greenhouse gas emissions - As biodiesel is green and non-toxic, it also provides considerably fewer combustion emissions which eventually results in a significantly reduced emission of carbon monoxide, NOx, and unburned hydrocarbons. Along with its low sulfur content, it certainly does not compromise with its natural thickness and lubricating properties. Biodiesel, thereby does not burn sulphur dioxide(with help of vegetable oil in it) and also helps reducing the green house gases release. It burns cleaner than the very low diesel. It is scientifically proved that it has potential to reduce emissions of greenhouse but, it also provides latent benefits to human health too.
Biodegradable - Biodiesel is biodegradable, which is definitely a positive trait it possesses. It informally means that, it is environment-friendly as it is a sustainable, 100% renewable resource. Biodiesel is safe and sound to handle and transport because it is as biodegradable as compared to sugar, 10 times less toxic when compared to table salt, and have a high flashpoint of about 300 F if compared to petroleum diesel fuel, which has a flash point of 125 F.
