How do I dispose of my used fixer?
Used fixer contains silver , whose discharge is usually regulated. It is also very valuable, so don’t just throw it away!
This is particularly relevant for people using “well water” and spaces that use large amounts of fixer like a university. Please contact your local hazardous waste or chemical disposal company for best practices and recommendations for proper disposal. There are systems for the home and darkroom for silver recovery. Please take care of the environment; we would like it to last a bit longer.
