Ethol UFG on TMax or equivalents. It looks like fixer with a simple
treatment (desilvering) is dumpable, but what about the developer and
stopbath? I am on a septic system and don't want to spoil a good
system.
Any suggestions either in disposal or alternative products is welcome.

Use White Vinegar - a teaspoon or two to a quart of water, for your
stop bath.
That was the first thing the guy told me when I bought my very first
darkroom equip back in the mid 70's -
Better for you, better for the earth.

Ilford's indicator stop bath is relativily cheap, lasts forever and I've
yet to use up the bottle that I bought more than four years ago. (My
film use has been rather low lately), it's even more benign than white
vinegar, it's made of coelenterate Citric acid, basically vitamin C.
