Making Biodiesel

• Small Scale Biodiesel Production (PDF - 21 pages) - This report made by ISTC gives an overview of producing Biodiesel on a small-scale.

Biodiesel is produced through a chemical process called transesterification, involving the separation of glycerin from fatty acids and binding of those acids to alcohol molecules. Any vegetable oil, not just soybean oil, may be used, as well as animal fats. Oils from algae may also be used. See the National Biodiesel Board fact sheet on biodiesel production for a general overview of the process. That organization's fact sheet on biodiesel production and quality is also useful. Collaborative Biodiesel Tutorial website provides detailed information on biodiesel production, including photos and recipes.

A growing number of private citizens are producing their own biodiesel using commercially available kits. The Collaborative Biodiesel website provides a list of biofuels supplies and suppliers. The National Biodiesel Board provides a similar list. ISTC provides links to these lists for informational purposes only; links should not be construed as an endorsement by ISTC of any of the suppliers or technologies highlighted on these web sites.
