Depending upon the film developing and printing process, I'd expect the photography waste to be a TC waste for silver.  The pH will normally be characteristic greater then 2 and less than 12.  If the waste water from your institution is discharged directly to a publicly-owned treatment plant (POTW), I would contact the POTW and inquire if they have a pre-treatment permitting system that would allow for a one-time discharge of a known quantity of photo processing liquids to the plant.

With regards to the paint waste, if the paint is still usable, but no longer meets the "shiny" or "shimmering" needs of the Art department, the Theater Arts department may find it useful for painting sets.  Otherwise, consider preparing commodity packs of similar paint types for ultimate disposal.

Respectfully yours,

Hi everybody,


It seems suddenly this semester the Art department doesn't know what to do with their waste from painting and photography courses-and now my department is going to manage it.


If there is anybody out there who has experience with this, I would greatly appreciate it.    I know how to manage their initial influx of "unknown" and "mixed" waste, I was just hoping someone might already have a program on hand for some organizational guidance.  In other words I really don't want to reinvent a brick-.
