Biodiesel is created by removing a thick liquid called glycerin from soybean oil. It is registered with the US Environmental Protection Agency as a pure fuel, which is known as B100, or as a fuel additive, which is called B20, a mixture of 20 percent soy and 80 percent petroleum-based diesel.
There are many benefits of soybean fuel.
Studies have shown that biodiesel from vegetable oil reduces petroleum consumption when used in place of petroleum diesel.
In addition, the use of biodiesel reduces CO2 in the earth’s atmosphere. This is due to the fact that growing soybeans consumes nearly four times as much CO2 as the amount of CO2 produced from biodiesel waste gases.
If you ever want to take a ride in a car or bus powered by soybeans, you can. The Agriculture Research Center (ARS ) National Visitor Center bus, which is used for Beltsville, Maryland farm tours, is running on biodiesel fuel.
ARS scientists are conducting biodiesel fuel research, and they are trying to find ways to make fuel from vegetable oils, animal fats, and used restaurant oils.
Biodiesel fuel costs more than regular diesel fuel. However, the price may drop if people use it more. We can look to the future with the hope that clean fuel sources will continue to be widespread in the United States and even around the world.
