Biodiesel fuel stations are facilities that provide biodiesel, a renewable and cleaner-burning alternative to traditional diesel fuel. Biodiesel is made from natural sources like vegetable oils, animal fats, or recycled cooking oil. These stations cater to drivers of diesel vehicles who want to reduce their carbon footprint and support sustainable energy practices. At biodiesel fuel stations, customers can fill their tanks with biodiesel blends, which are often labeled with a "B" followed by a number indicating the percentage of biodiesel mixed with petroleum diesel. For example, a B20 blend contains 20% biodiesel and 80% petroleum diesel. These stations contribute to the growing network of alternative fuel options available to consumers, promoting environmental sustainability.
