Biodiesel is a clean burning diesel replacement fuel derived from biological sources such as new and used vegetable oils and animal fats. It was created and is specially made in Brazil, a world leader in alternative fuels. Just like petroleum diesel, biodiesel can be easily used in diesel-engined vehicles. It reduces the amount of harmful emissions that are released into the environment and because of it being a "cleaner fuel", it is used as a fuel additive and to supplement petroleum usage.
Biodiesel is biodegradable, safe, and reduces many air pollutants such as carbon monoxide, hydrocarbons, and air toxins. If pure diesel is used in a vehicle, it can reduce carbon dioxide emissions 75% more than standard petroleum diesel can. Using a blend of 20% biodiesel reduces carbon dioxide emissions by about 15%.
Biodiesel can be used in pure form (B100) or may be blended with petroleum diesel at any concentration in most of today's diesel engines. Biodiesel has a tendency to wear down rubber hoses and parts in a vehicle, but due to newer manufactured rubber parts, this is no longer an issue. Biodiesel is also safer than petroleum diesel because it is far less combustible, and it is safe to transport, store, and handle.
Biodiesel is a much better alternative to petroleum diesel and is much better for the environment. It is easily created from animal fats, vegetable oils, or recycled restaurant greases. It is a clean fuel, and it is expected to gain popularity and respect as an alternative fuel source.
