Have you tried Kodak itself? I have received info on Kodak's
chemical recycling program; perhaps they also offer services or
contact info re. film recycling. Number I have for Kodak
Environmental Services is 716-477-3194. To check with other
potential markets you will probably need more info on the type of
material the film is made of and amounts generated.
You might get some ideas from the Recycler's WorldWWW site at
