The environmentally unsafe problems of silver reclamation, as well as the humanly unsafe problems associated with ammonia, have been eliminated from the photo plotting process with the Dry Process Direct write systems. The Graphics Art industry has been using the Lino-Type Hell (Heidelberg) Dry Setter photo plotter and Polaroid Dry Imagesetter film for several years now with great success, performance wise as well as environmentally and ecomocally.
I hesitate to use this forum for marketing purposes, however, not being the first to do so, I should point out that AOI International is now installing several Polaroid/Heidelberg systems in PCB shops after an extensive testing and evaluation period.

Subject: RE: handling silver halide wastes
I've noted several posts about handling silver bearing wastes & wastewater
and I have some comments as an industrial waste inspector that may (or may
not) be useful:
The EPA considers wastewater from film developing to be a Printed Circuit
Board Manufacturing process water just like the water from plating, etching,
etc. is. This means that you don't have to meet the federal silver limit
until the wastewater is mixed together & being discharged, the significance
of the legal *dilution* with non-silver bearing wastewater obviously
depending on the volume of your other rinses. Obviously if your
film/artwork site is in a separate facility or you drain wastewater from
there separately from your plating area this doesn't apply.
I'm not putting down waste minimization, far from it. There are many cost &
regulatory benefits to waste minimization in addition to my narrow focus of
pollutants to the sewer. I put in my two cents worth since previous posts
seemed unclear on where federal silver limits would be applied, which may
affect the business decision of what to spend on silver treatment.
