Biodiesel
Biodiesel is an alternative fuel made from renewable resources such as vegetable oil and fat and can be used in diesel engines with little to no modification. The fuel burns more cleanly than traditional diesel and is non-toxic. It can be combined with traditional diesel to increase performance, especially at cold temperatures. Mixtures are denoted by the abbreviation ULSD/B#, which indicates the use of ultra-low sulfur diesel and biodiesel of a certain percentage, indicated by the number.
Yale is reducing transportation-related emissions by running the bus fleet on ULSD/B20 biodiesel. ULSD/B20 biodiesel reduces the sulfur content from a regular diesel level of 500 parts per million to 50 parts per million. The use of biodiesel also reduces Yale’s transportation-related petroleum usage by 20%, or 20,000 gallons.
