Earth911 is the largest US recycling directory: pick a material (film, foam, electronics, textiles) and a ZIP code to find drop-off, mail-in and donation options. It is run by Earth Media Partners, a company, and listings are only as current as the last update.
Honest caveat: the search sub-domain timed out once during our check; retry if it fails.
