Paper Abstract

The silver halide film imaging industry traditionally has not been considered a major polluter. Still, today we face increasing sewer discharge controls for used processing solutions. The environmental community recognizes an emerging hierarchy of waste management. In decreasing level of desirability, this hierarchy includes: make no waste (Green products), recycle, minimize generation of waste, and disposal. Efforts to manage black and white silver halide films processing effluents within the hierarchy are discussed.
