http://www.thegreenbeat.com . Biodiesel is an EPA-approved alternative fuel made from renewable plant stocks such as sunflower, rapeseed and soybeans. Although the most common feedstock for biodiesel in the US is soybeans, it can also be generated from any vegetable or animal fat (triglyceride) including waste vegetable oils. USDA research indicates that pure biodiesel reduces net CO2 emissions by 78% compared to petroleum diesel. When used as a 20% blend, biodiesel still drops CO2 emmissions by 15%. Biodiesel also has a significant lubricating effect which can offset engine wear: a 1% biodiesel blend can increases fuel lubricity by 65%.
Not everyone has the convenience of a local commercial biodiesel distributor. Even where these are available, the cost of biodiesel can be prohibitive relative to the cost of petroleum based diesel. In other cases, bioidiesel may not be available as a 100% product. As an alternative, some consider making their own 'homebrew'. This is biodiesel rendered from waste vegetable oil and animal fats. I prefer this alternative since it uses local materials that require negligible refining and transporation costs. By using local waste materialsl, we can futher diminish our environmental footprint. This video provides some basic information regarding the benefits, risks, and chemistry with respect to homebrew biodiesel.
