Biodiesel Fuel

Renewable Fuel made from Waste Cooking Oil

Biodiesel is a renewable replacement for petroleum diesel fuel that drastically reduces emissions. It works in most diesel engine applications with little (or no) modifications/changes to how you use your engine. Our student-run business has been producing biodiesel since 2007.

See how our Biodiesel Production happens as part of Loyola's Zero Waste Process.

Loyola sells 100% biodiesel that our students make from waste cooking oil collected from cafeterias on campus (and from donations from all around Chicago). Our fuel is available for sale in bulk quantities (55–500 gallons) and ready to be used on its own or blended with petroleum diesel fuel. We are proud to use this fuel on our own campus in our shuttle buses and a boiler in the School of Environmental Sustainability.

The Loyola Biodiesel Program is fully licensed to produce and sell fuel. That means that all of the applicable fuel taxes are paid to; our process is reviewed/audited for safety; and our finished fuel is tested for and meets all industry specifications for quality (ASTM D6751). We test our fuel in our own fuel quality laboratory and confirm this with external (third party) lab tests as well.
