Much of the fear of photochemical processes is ignorance. A good lab recaptures it's waste silver, as I do. Personally I don't like the packaging waste, and the fact that Kodak et all do not have a program that I am aware of to recapture and reuse these materials. I have piles of 35mm canisters, the plastic containers, 120 reels, backing paper....it adds up. That's the only aspect of the form that really bothers me. I try to justify it however by realizing that after 2 weeks or so in my changing room I come away with 1 large trash bag of 120 detritus. That's not so bad, but as I get busier of course...well more waste! At some point there will need to be a way to make these things out of at least biodegradable materials. Or Kodak should accept the 120 reels and plastic canisters.
Plastic recycling is largely a scam, and few plastics are actually recycled. :-(
