Biodiesel is a renewable fuel that is manufactured from vegetable oils, animal fats, or recycled restaurant grease for use in diesel equipment. Biodiesel’s physical properties are similar to those of petroleum diesel, but it is a cleaner-burning alternative. Kentucky produces 68 million gallons of biodiesel from soybean and recycled vegetable oil.
Renewable hydrocarbon biofuels are fuels produced from biomass sources through a variety of biological, thermal, and chemical processes. These products are similar to petroleum fuels in chemical makeup and are therefore considered infrastructure-compatible fuels. It is expected that these fuels can be used in vehicles without requiring engine modifications and can use existing petroleum fuel pipelines and retail distribution systems.
UPS installed two biodiesel storage tanks on the Worldport property in Louisville in April 2011. The installation was part of UPS’s goal to reduce their carbon footprint 20% by 2020. The 30,000 and 5,000 gallon tanks enable UPS to provide biodiesel usage in over 300 pieces of ground support equipment.

Mammoth Cave National Park
Mammoth Cave, KY
Mammoth Cave National Park (MCNP) has been using biodiesel for years, and is the first national park in the country to be powered by 100% alternative fuel. They use B20 in all diesel vehicles and support equipment, including ferries that navigate the Green River. Mammoth Cave National Park sits on more than 52, 000 acres and has 80+ employees. This was the first 100% alternatively fueled national park in the country of 385 national parks in all.
