Green spud gun propellants?

In terms of spud guns, I'm assuming that the standard propellants aren't quite "green". Does anyone know of another way of doing it?Or is it innately eco unfriendly?

Dont listen to Fozzy, you WILL die. Not MAY die. Sooner or later it will blow you in half. Compressed air is best. Combustion guns work best on propane air mix.
