in the process of moving our ink room, we've found we have a lot plastisol we no longer need, and is very old.
Best way to dispose of it?
-
Depending on just how much, I've spread it on cardboard and run it through a slow dryer.
Heck, I remember someone going one better using the process and making door mats out of the stuff.
Of course, the other thing to do, when possible is to use the stuff. All mixed up usually gives a dark gray that when when based down makes great tone-on-tone prints (but because of the base doesn't use a lot up.
With some black pigment added, it could provide a lifetime supply of black ink.

Donate to a smaller local shop?

Offer for free on Craigslist. We did this & got rid of a ton of old sign ink we didn't need. Gave me a friendly introduction to another local printer, too.

triple bag it and throw it in your competetors trash can...just kidding..i like the donate it to a small local shop..or craigslist..its really hard to sell old ink, oh and there is always drum it up and call safety kleen..

If it's really old and that is no longer phalate compliant cure it cookie sheets or place buckets underneath an IR panel flash ad they will cure all the way through.
You can get 55 or 30 gallon drum fill it up and have it hauled off as waste

I purchased an old bench-top lab oven for curing waste ink ($50). I put about 1.5" in a foil catering pan and cure it at 300 degrees until it's solid enough to be peeled out of the pan (maybe 10 minutes). I also cure old ink containers, but that plastic will melt at 300 degrees, so it requires closer attention.
