Cartridge Unit
means any variety of
				hollow canisters containing steel wool or fiberglass fibers impregnated with
				iron filings which are used for silver recovery. These units use metallic

Photo Processor
means a facility, as
				defined in
				310 CMR 71.00, that performs
				the chemical process by which photographic film is treated after photographic
				exposure to produce a negative or positive image (
e.g
.,
				processing color prints or slides, or black and white prints or slides). Photo

Photo Processing
