Obviously, the device's components all have their place in the world. The arming components most likely are destroyed by shredding and/or smelting down to slag. The explosives are taken to White Sands or a similar location for disposal by EOD.
Now the fissionables, you know the major components are all isolated and kept in separate, classified locations so they could not be recovered by Threats for reassembly. The big parts is Uranium (big surprise) and Lithium 7 Hydride. The former can be refined and used in reactors of many types. The latter can be reprocessed and used in power cell production.
PU, OTOH, is a tricky beast. There is so little due to the "spark plug" Lithium component used in 3 Stage "Super" Thermonuclear devices. But its rare and not used in public or commercial projects without severe restrictions. So it can be reprocessed into 238PU02 Oxide. Which is used in SNAP RTG's. The PLOWSHARE program which took nuclear weapons from countries broken away from the dissolved Soviet Union, was reprocessed to be used in RTGs for spacecraft.
