I have been looking for information on burning hdpe and ldpe bags and haven't found anything. I wrote a little article on the subject for my sustainability-related newsletter, putting in the information I could find, but there were further questions. My municipality, Yonkers, NY, doesn't recycle plastic bags even if they are of the same material as other things that they do recycle (hdpe) and only recycles #'s 1 and 2. For the rest I'd like to do something better than put them in a landfill, and burning seems like one option. However, does burning these bags release benzine rings? are the (frequently yellow and tan) dyes used to make these as persistent as, say, Yellow 5 and other things equally harmful? If they're burned in a fire pit, is there harmful off-gassing or do they stay pretty much in the fire pit? Is there a good source for information on this subject?
Thanks very much.
