You can also do some interesting development with non-toxic stuff like
coffee and tea (and ascorbic acid):

I have pretty similar feelings. I don't miss film at all. I get
much better control and results from digital. Not to mention, much
more practice and improvement in my skills (photographic, not lab)
without a such a big hit in cost for all that film. Other areas
besides cost that bothered me wit

Stop bath is essentially dilute acetic acid, same as vinegar. The
advantage of Kodak Indicator Stop Bath is that it has a dye in it that
turns purple
This is the best choice - to take all your old chemistry to a household
hazardous waste pickup point so it can be dealt with properly.
Putting them into your septic system creates two issues. The first
being any potential damage to your septic/soil absorption system and the
