There exists a type of resin called Ekimate in Japan which is much less smelly/irritating than most resin formulations, costs ~3X as much, and which represents itself as being pourable down the drain in a matter which suggests to me that lawyers/etc have reviewed the claim and think it is within appropriate bounds for marketing material made by chemical manufacturing companies. I do not pour it down the drain. If I had a high tolerance for running wonderful small businesses with inventory, I would try to get their exclusive license to distribute in the US and make it a thing; it’s an obviously better (though premium) product than any other resin formulation I’ve seen.
My liquid waste gets cured outside in sun for several days while evaporating to reduce volume then wiped up with towels and discarded in standard (burnable) trash; my solid waste gets cured out of an abundance of caution then discarded in standard (burnable) trash. I have immaterial use of IPA which is not discardable in trash but which also evaporates easily, and simply let it evaporate outside after I am done with it (after cleaning/reuse cycles).
I use exclusively water soluble resins.
