Pollution Prevention Top Tips for Photo Processors
Be sure your used fixer is properly treated, either by adequate on-site silver recovery or off-site
treatment. If you use on-site recovery units, be sure to properly operate and maintain them. Also, be sure
your discharge is meeting local and state limits for silver.
- Recycle photographic film and paper.
- Never put used fixer down the drain.
- Reclaim and recycle silver from photochemical wastewater.
- If you only use chemical recovery cartridges to do on-site silver recovery, consider mixing used bleach with your used fixer and wash-less stabilizer prior to recovery.
- Do not put bleach into an electrolytic silver recovery system.
- If you send silver-bearing chemicals off-site for recovery, ask your service company if they will accept
C-41 RA bleach and wash-less stabilizer for pick up.
- If you do on-site silver recovery, mix used wash-less stabilizer with your used fixer and bleach fixer
prior to recovery.
- Don't ever put stabilizer into a septic system, storm drain, dry well, onto the ground, or into the sanitary sewer.
- Consider using low replenishment developers for both film and paper.
- Where possible, use developer with less than 1% hydroquinone.
- Routinely test the silver levels in your wash water to ensure compliance with silver discharge limits.
- Don't put developer, bleach, or activator solutions from "silver master" in to silver recovery
