I have a 3L jug of SLA printer-related waste that's been sitting under my desk for a while now and I'd really like to finally figure out how to get rid of it. It contains:
- Ethanol (primarily) and isopropanol, saturated (in the literal sense) with uncured resin (photo-polymers, photo-initiators, binders). Note there is likely very little water left (started with 90% ethanol and 99% iso, sieve-dried multiple times).
- About 10% by volume undissolved waste, a slimy gray slurry of: uncured resin, a significant concentration of glass fibers, and some uninteresting filter waste (charcoal, sodium bentonite, probably some sieve dust, etc.)
Also it smells awful when unsealed, numerous recyclings through filters have left it disproportionately saturated with god knows what. It smells like ... pine and cancer.
How do I get rid of this? Is there some way I can process it myself to make it environmentally friendly? The uncured photopolymers are the worst offender, I believe. Plus the whole thing is very flammable.
Location: NYC (Kings County), NY USA
Also: I don't mind going through the effort of processing it myself if it keeps it out of the ocean or some landfill somewhere. Plus, I'll be continuing to generate this waste in the future (low volumes; probably about 1L per month at the highest rate) so I don't mind investing in a processing setup.
