For cultural context to this from the American side, as I recall, in the US military, if an American flag has become desecrated by allowing it to touch the ground, tradition was for it to be disposed of by burning. If this rule is still followed, I would expect burning would seem the obvious way to respectfully dispose of any desecrated sacred item.
