How does the silver recovery cartridge work?
The silver recovery cartridges work as ion exchange. Ion exchange is the
reversible exchange of ions between solid iron and silver in liquid. Ion
exchange has shown to be very effective, recovering as much as 98% of the
silver and achieving effluents with silver concentrations as low as 0.1 ppm.

used cartridges do not have to be classified as hazardous waste as long as
they are being sent for refining.

In our processing, we use an environmentally safe proteolytic enzyme solution
bath to remove the silver from the film. The plastic base for the film is used in
the plastic recycling industry. Once the silver emulsion is removed from the
plastic base, there are no markings or identifying characteristics on the plastic.
