Many of the school buses in Kentucky started using biodiesel blends in 2006 to provide cleaner air for the students they were transporting. 

UPS installed two biodiesel storage tanks on the Worldport property  to use in more than 300 pieces of ground equipment. This was part of UPS’s goal to reduce their carbon footprint 20% by 2020. 

Who Uses Biodiesel in Kentucky?


Mammoth Cave National Park has been using biodiesel for years, and is the first national park in the country to be powered by 100% alternative fuel. They use biodiesel in all diesel vehicles and support equipment, including ferries that navigate the Green River.

Kentucky farmers use biodiesel in their farm equipment where available. They are producing the soybeans which may eventually be used to make their fuel. 

Biodiesel is also used by many companies and governments in Kentucky looking to source local fuel and reduce their carbon footprint.

Carmeuse uses one million gallons of biodiesel per year in their two lime mines located in northwestern Kentucky. 

How It's Used

One of the great advantages of biodiesel is that it can be used in existing diesel engines, vehicles and infrastructure with little to no changes. Biodiesel can be pumped, stored and burned just like petroleum diesel fuel.

Biodiesel blends of 20 percent and below will work in any diesel engine without the need for modifications.  These blends will operate in diesel engines just like petroleum diesel. 

Most diesel fuel in Kentucky is blended with up to 5% biodiesel.  Blends up to 20% provides similar horsepower, torque, and mileage as regular diesel.

Ways to use biodiesel:

  • Personal diesel vehicles
  • Commercial trucks and buses
  • Tractors and farm equipment
  • Contstruction and mining equipment
  • Airline and airline support equipment
  • Boats, barges, and ferries
  • Trains
  • Electric generators
  • Stoves and furnaces
