Mixing chemicals for disposing?

Are there any chemicals that are OK to mix in one vessel pending disposal?

As it is now I get LOTS of bottles to deliver to the disposal station.

BW developer
BW fix
C41 developer
C41 blix
C41 Stabilizer
Sepia toner part A
Sepia toner part B
Selenium toner
Gold toner

It would be very nice if some of these chemicals could be mixed safely into one vessel.

Suggestions?

Thanks in advance,
Henning

To me, that mix looks like two bottles. One of everything but the toners and the other a very careful trial mix of the toners. The sepia toner and the selenium toner may cause some gas to form under some circumstances so give a try to a small amount first. If nothing bad happens then you have reduced them to 2 bottles. Oh, and a reaction may not start right away so with any of this, leave the cap off or loose for a few hours - days before you tighten it.

The formation of gas with rupture of the bottle is the biggest problem.
