P2tech listserv.

The Crane Naval Surface Warfare Division is a large industialized
facility with many photographic needs - technical and otherwise. We
have eliminated use of all chemicals in our photo processes by using
digital photographic equipment. We eliminated purchase/ use of 28
hazardous materials, 500,000 gal / yr rinse water, 11,000 gal / yr of
photographic baths/chemicals. The initial investment was $210K, but
we are expecting to save $190K/yr after the first year. The process
is 3 times faster than the traditional method. It consists of digital
cameras, scanners, computer workstations and printers.

Hi all!
I am in research of pollution prevention for company 'Disc Graphics'.
The information received from company is incomplete, but I know they
have waste water of 200gpd in out side collection tank after silver
recovery. In darkroom they use photochemicals like fuji and 3m sys. Is
there any latest technology cheaper and beneficial? sorry for long:-
any suggestion would be appreciated. Razan, Suffolk County Water
