I've been wondering about something for a while now: I use up certain materials in my darkroom, but I don't know whether they can be recycled. I'm not talking about chemistry here, but rather: paper -- RC paper, in particular, seems rather unlike the typical office paper that I put out for recycling. I've been assuming it can't be recycled, but if I can recycle my test strips, bad prints, etc., I'll start doing so. FB paper seems, to the eye and touch, more like office paper, but I don't know if the emulsions or other features might cause problems. glass -- I have yet to break or otherwise "use up" a glass bottle, but when I do, can I put it out for recycling with my other glass items? Will the cloudy deposits I see on some glass jars cause problems at the recycling center? If so, which products, once stored in glass, make it dodgy to recycle? plastic -- Pretty much the same question as for glass, except of course that some chemistry (Rodinal, most color developers, stop baths, etc.) come in plastic bottles to begin with. These are invariably marked with recycling symbols, so I've been assuming they are recyclable, once washed. Any tips are appreciated.
