Do not put propane tanks in the trash — solid waste equipment can rupture the cylinder and any spark can cause an explosion, and you should never attempt to de-valve your own propane tank (New Hampshire Department of Environmental Services).
Do not dispose of your cylinder in a dumpster or other disposal container — this could create an explosion hazard; and avoid cutting the tank or wheel valve with a torch (Maryland Department of the Environment).
