Disposal of Old Resin

I have an old bottle of porridge (resin left over from cleaning tanks after failed prints) – How do I get rid of this stuff?

I read through the MSDS for the black resin and found the disposal section which is a big vague. I can’t really contact a disposal company to get rid of it for me… That’s not really practical.

I don’t want to pour it down the drain. I have a blacklight I can use to cure the resin (to throw it away) but it only cures the first millimeter or so.

You could probably put it in a large freezer bag and lay it in direct sunlight a few days.

I definitely would not pour it down your drain. Josh’s recommendation is good…we often lay resin out in the sun here in ziplock bags. Once the resin is cured, you can dispose as normal trash.
