OK, this is my first trip on the forum and I'm unsure if posting in the correct area. After viewing past threads, I wasn’t able to locate an answer to my dilemma, but it’s more than likely discussed somewhere. Upon tackling the task of cleaning my uncle’s estate, I encountered numerous shoeboxes containing photo negatives dating back to the 1930’s, 1940’s, and some 1950’s, stored in the attic. I thought I struck gold finding family heirlooms, but unfortunately most (if not all) are totally faded and brittle with no image viewable. Since discarding is my only option as I don’t think attempted scanning is of benefit, I’d like to know the best way to do this. There is no recycling in my community, other than computers and appliances. Due to the chemicals used on old negatives (one box has a vinegar smell) I doubt that it would be considered safe to toss them in the trash to end up in the landfill. Does it make a difference if they’re shredded? Are there safety issues? Thanks in advance for the expertise.
