- Solvents: Avoid F-Listed Solvents - If your cleaning solvents contain any of the chemicals shown below, equal to or above 10% before use, they are listed hazardous for disposal. Because of their high flammability, persistence or toxicity, these are hazardous compounds. (Certain mixtures of these may not be F-Waste.)
Look at your MSDS to find these chemicals
||Methylene chloride (dichloromethane)
||1, 1, 1 -trichloroethane
||Methyl ethyl ketone (MEK)
|Cresols and cresylic acid
||Methyl isobutyl keto (MIBK)
- Changing to water based inks will eliminate the need for these solvents. If you cannot change to water based inks, work with your vendors and suppliers to find safer solvent alternatives.
- Change to low VOC inks, washes and fountain solutions.
- Don't saturate towels with solvents or put in press trays to soak up ink cleanup waste. Use cloth shop towels that can be laundered, not discarded.
- Store solvents and used shop towels away from dryers and other heat sources. Keep used towels in closed metal containers away from haze and emulsion removers containing sodium metaperiodate crystals.
- Switch to electronic imaging.
- Use pump bottles or plunger cans for solvent.
Reuse and Recycle:
- Recycle cardboard and other bulk material. Less waste in the dumpster means lower disposal costs.
- Purchase frequently used materials in bulk to minimize container waste.
- Recycle spent solvents, scrap film, plates and make-ready inks.
- Used fixer has a silver quantity exceeding hazardous waste discharge limits and should be treated, sent to an off-site collection service or larger business that has silver recovery equipment or reclaimed using a minimum of two chemical recovery cartridges in series, on site.
Separate wastes, label containers and put containers in one area:
- Examples: Ink Cleanup Sludge Only, Waste Ink Only; Used Shop Towels Only; Used Fixer Only; and Scrap Film Only.
