Abstract
A cartridge that supplies fresh photographic processing solution or chemistry to a photoprocessing machine and recovers silver from spent processing solution. The cartridge is designed to integrate a solution supply system and a silver recovery system to facilitate the collection of silver from spent processing solution, form a less-regulated spent solution and reduce chemical exposures to operators of photoprocessing systems.
