Deb: I have to agree with Steve in that I have never seen any data to support the claims made by Chemgon. I have seen the product literature, but am not aware of anyone actually using it. While the technology appears to be able to solidify the silver, data on the fate of the silver via TCLP testing is essential. I would also be concerned that this activity could be deemed to be considered treatment of a hazardous waste by one or more state regulatory authorities and could require a permit, fees, and employee training. 

From a sustainability perspective, landfilling a precious metal should not be encouraged. If economically feasible, it should be recovered for reuse and there are plenty of companies that have recovery equipment and are willing to refine the silver. It is also important to recognize that some states consider silver recovery treatment and could also require permits, fees, and employee training.
