After the holidays I'm going to contact my local waste management facilities and see what they say. I'm curious what other people do.
Long story short, earlier this year I ordered some plastisol from Bait Plastics that was terrible. Loads of bubbles, but worse than that, it burns very, very quickly and easily. I have to add a good bit of heat stabilizer just to prevent it from scorching before it hits 350 degrees. And that's with very careful microwave usage, heating in small increments in ideal heating zones in the microwave. I just gave up on it a while back and I'm going to just dispose of the remaining half gallon or so I have left after hearing what my local waste management people have to say. I've had someone else tell me to "cook it into a puck and then recycle it". Problem being that it burns before it hits 350, so it's not going to get that reaction. Also I'm not sure if it's recyclable in the first place.
