In my household we're pretty maniacal about recycling absoluetly every item and material that we can. I do not live in the land of curbside recycling. We have a wall of bins in our garage and we have to shchlep everything to appropriate drop off points. Some items must be horded till we have enough to justify a trip.
Computers and electronics go to a recycling center. My spent pyro goes to hazardous waste. My fix goes to the recovery tanks at a university photo dept. I try to minimize water consumption and release to the environment (I'm on septic).
I spend a lot of thought and energy on this stuff. I try to make the best decisions. I spent a fortune putting high efficiency HVAC in...I'll spend another one on tighter doors and windows. We're gradually transitioning to CF's because I think that on balance, with the present choices, they make the most sense, imperfect as they are.
Part of my motivation for all of this is to be the best environmental-citizen/photographer I can be. Handling chemistry responsibly makes much more sense to me than the more 'libertarian' approach.
