If you choose check with local authorities, ask their permission for what you intend to do, and they say no, I guess you have to comply.
hi maris

your calculation is a little off ..
there is about 1/4 oz of silver in a gallon of well spent fixer.
i am not sure how much film or paper that is in a year, or how often you
use a gallon of fixer, but its about 1/4 oz/gallon ....
