Silver recovery makes sense if it's easy (e.g., photofinisher in the area, etc.) but if not, down the drain it goes for me, especially after my hazmat experience with fixer. FWIW, I routinely disposed of relatively small amounts of fixer and other photochemicals into a septic system for years with no ill effects whatsoever.
As for selenium toner, I replenish and reuse and never have to dump any (just what comes out in the wash).
Best,
Doremus
