Do they really think that a little bit of chemical waste that a selective group of people (us APUG-ers) dispose in the sewer will distroy the world? And the chemicals we all (well not all, but a lot) use to clean the toilet, use to color our hair, nail remover etcetera doesn't effect the inviroment?
Many developers are closely related to chemicals used as drain cleaners.
People use so many chemicals every day, without thinking, it's not even funny. One turn of the ignition key as you get into your car, going to work in the morning, spews more toxic waste than most people can conceive. It is my understanding that it takes one acre of grass and forest to absorb the pollution expelled by the average automobile driving one mile. Then, as Steve says; drain cleaners, window cleaners, kitchen cleaners, bathroom cleaners, etc., etc., etc. We sure dirty up the environment an awful lot in the name of getting clean!
It is my understanding that, in the moderate quantities that the average home photographer disposes of, a well operated municipal sewer treatment plant will destroy most of the stuff we flush down the drain. The exceptions being silver-saturated fixer, selenium and other exotics. From that, I understand that the CORRECT thing to do is to flush your "standard" developing chemicals down the drain with plenty of water. Again, the key is MODERATE QUANTITIES. If you're flushing five gallons of developer per day, that's not moderate. If you're developing a couple of rolls per week, that's a different story.
I also believe, if memory serves, except for fixer, it is Kodak's recommendation to flush moderate quantities of developing chemicals down the sewer, using plenty of water to dilute.
It is also my understanding that Kodak recommends anybody disposing more than moderate quantities of chemistry that would be generated by the average home developer to contact their local authorities and seek advice or proper permits.
So, yes, this does go right along with the theme of assumption. Most people assume that photo chemistry is the same as nuclear waste but we all know it is nothing of the sort. While nobody would say that photo chemistry is harmless, if handled properly, used properly and disposed of properly, it's nowhere near as harmful as the masses often assume.
With proper respect, due caution and careful treatment, photo chems are, as Douglas Adams might say, are "Mostly Harmless."
