Biodiesel is a renewable, clean-burning fuel made from a variety of natural sources, such as vegetable oils, animal fats, or recycled cooking grease. It’s an eco-friendly alternative to traditional diesel fuel, designed to run in diesel engines with little to no modifications. Biodiesel is produced through a chemical process called transesterification, which separates glycerin from the fat or vegetable oil. The result is a smoother burning liquid that emits fewer pollutants than petroleum-based diesel. Because biodiesel comes from plant and animal sources, it’s biodegradable and contributes less to global warming since the carbon dioxide it releases is absorbed by growing plants. Its use reduces dependence on fossil fuels, promoting energy independence and supporting local agriculture and recycling programs. Biodiesel can be used in its pure form or blended with petroleum diesel in any proportion. The most common blend is B20, a mix of 20% biodiesel with 80% petroleum diesel, offering a balance between reducing emissions and maintaining fuel availability and engine performance. As technology and production methods improve, biodiesel is becoming an increasingly viable and popular choice for fueling vehicles, heating homes, and powering industrial equipment.
