I'm not sure what was suggested earlier because I didn't keep up with the posts, but if the glue is a phenol aldehyde combination, you might be able to reverse the chemical reaction to break down the chemicals with acetic acid solution. I'll bet vinegar is too weak. If you have access to dilute hydrochloric acid, that might work faster. Heat will speed up the process. I've never tried it before, but that's the first I'd try.
