The biodiesel refinery is a building in the Mojave Wasteland in 2281. It is found in the northwestern part of Nellis Air Force Base, next to some yellow train carts and a small tower.


The location consists of a single room. At one end sits a large stack of fuel drums and to the right, a counter where a large amount of maize can be found. It is full of flammable fumes.

Notable loot

Inside are 102 pieces of maize, the highest quantity found in the game.


  • Having a flame-based weapon out (such as the flamer) while near the fumes will cause an explosion. Firing any Energy Weapons, Guns, or Explosives skill weapons inside will always cause an explosion. Even the BB gun will cause one.
  • The large amount of maize found within is a reference to real world biofuel which is often made from corn.


The biodiesel refinery appears only in Fallout: New Vegas.
