Disposing of old polyester resin
 

I've got some dribs and drabs of polyester resin in the bottom of some pails
and cans that I'd like to safely dispose of. Some of it has crystalized and
I also made the mistake of dumping some left-over resin from one distributer
into the container of another creating a weird jelly like substance that
refuses to cure in any fashion.

Should I just drip in some MEKP into the containers, or is there a better
way?

I would mix up a cup of fresh poly resin and pour into the bucket, mix
it all together as well as possible, making a solid (as much as
possible), then dispose of normally.

If you want the official solution call your local waste managment
facility.

In a lot of places, that would just bring more attention to you. I
think the other posters idea of throwing out a big ball of plastic is
probably best.

No, if the OP only has a few gallons of junk resin, it should go where
it belongs- the waste management facility. Should be able to get rid
of small amounts at no cost.

55 gallon drums might be a little different but certainly cheaper to
dispose of properly than to pay the fine for doing it wrong.

Sorry if I gave the wrong impression. I don't advocate throwing goo
out. But a solid ball of plastic resin should be pretty much inert in
a landfill, and probably not against any regulations either. If it is
still gooey, that is another story.

I'm not proposing throwing out hazardous material, I'm saying that if
you were to mix a fresh batch of resin and mix in a mass of old, jelly,
it would cause it to all turn into a solid.

Works well with polyester, not so well with epoxy.

Oh, large amounts, that cannot be coaxed into becoming a solid, should
go to a hazardous waste facility to be disposed of properly. The
original poster said it was small amounts.

As it is, I have just a few ounces in the bottom of a pail and a few cans.
If I had more, I'd just save it for my next project.

The problem we have in our area is that we don't have a regular way to
dispose of "hazardous waste". My shed if full of old paint cans etc that I
can't take to the dump because they won't accept them. I'm in the process
of trying to have the goo dry out as that is the only condition under which
they'll accept them.

For the resin, I'm sure that they would stop me as soon as they saw the
hazardous goods label unless I can show them that it only contains an inert
mass.

You mention that there's a different issue with epoxy ... I have a couple of
small cans of that with dribs and drabs in the bottom - what's the
recommendation on it's disposal?
