Throw it all in the fire. Seriously. The primers will go pop, the powder will burn. No big deal.

We have a wood burning fireplace in the house, with glass doors. Under my loading bench I have a waste basket, used mostly for papers, old rags, etc, but often gets damaged, or for some other reason, live primers in it. We burn the waste in the fireplce and regularily hear "Pops," from the primers going off.
