This being legal shows the absurdity in same waste disposol regulations.
I have been trying to get my head around this issue.
I have got a few bottles of fixer and now whatever way I think of disposing, my head goes 'you're gonna be polluting the environment with the chemicals on an ongoing basis' - I still haven't gotten rid of the full dev - just a bit cos I knew it was spent.
Also, one thing I have noticed is that algae or lichen seem to find the area with a little bit of unwashed chemical as fertile place to grow - I keep the bottles n vessels out in the open, so humidity n temperature are mostly tropical.
So I'm not really sure if disposing down the sewerage is the best idea.
I am definitely not dumping it anywhere near the yard as our place is among the remaining few green spaces around for us and animals around.
So would the best course be turning it into paste n burning?

why don't you ask people in your town what you should do with it.

There is a lot of chatter about disposal of the liquids, but what about the eventual disposal of the plastic film and paper prints that will later become waste too?
There are companies that pick up b&w photographic paper and films to reclaim the silver, at least here in Europe. Of course they will not send a truck to you for half a dozen 4x5 sheets. They mostly cater for institutions where large amounts of such materials have to be disposed off.
I am not asking about local regulations, am I? So its not local regulations I am looking at.

Or what they can suggest on the course I am thinking of following.
See post #14.
So far no group established working on that idea.
I have taken chemical waste directly to the nearest sewage treatment plant and dumped it in their treatment ponds, after asking permission and telling them what I'm dumping of course.

they might charge 120$ so in the end it ends up being 2$/month to pay? it's really not that expensive, even if you are told to dispose of it once a year ...
trickle tanks can also remove the silver from your blix .. as long as the ph is between 5 + 6 you will be OK ...
