It appears that burning is also a viable method of destroying TNT. http://www.humanitarian-demining.org...tral/remic.asp
describes a method for destroying land mines "in situ" via burning.
It's a neat trick - a small shaped charge of explosive creates a
high-velocity gas jet which breaks open the (TNT-loaded) land mine,
and also delivers a charge of a pyrogenic chemical which ignites and
burns the TNT without detonating it.
Yep I have seen a documentary on TV where the cut open old WW2 bombs
(UK ones), and then simply burned the stuff in it.
That is how they get rid of the old bombs.
