Chemgon



Hi Everyone,

Does anyone know anything about a polymer called Chemgon?  
Dentists are using it as an alternative to silver recovery.  The used 
fixer is poured into a 5 gallon container which has a polymer that 
neutralizes and bonds to the silver, making the the solid 
supposedly non-hazardous.  The solid is disposed as regular trash. 
Do other states allow this?  It sounded like treatment and since 
many dentists could be Conditionally Exempt Small Quantity 
Generators, our state does not allow CESQGs to treat their waste.  

Anyway input would be greatly appreciated!  Thanks in advance!
