Why Change?

  • To gain or maintain market advantage
  • To improve operational efficiency
  • To avoid environmental regulation
  • To improve product and work environment or
  • To reduce risk exposure for employees, insurers, or creditors

How to Change?

  • Compare operations using a checklist
  • Generate options/alternatives for action
  • Ink
  • Fixer
  • Blanket wash
  • Fountain solution
  • Consider ramifications of alternatives
  • Act on best alternative
  • Evaluate change

Top 10 ways to improve your environmental and waste reduction activities:

  1. Use closed loop recycling of fixer, with silver recovery, instead of discharging the fixer solution down the drain or septic tank
  2. Use a variable flow rate when rinsing film instead of a continuous flow to reduce the amount of water used and contaminated by the film processing operation
  3. Recycle waste and scrap film, or use a direct to plate technology to reduce the amount of silver associated with photographic films instead of throwing away these types of films
  4. Recycle or reuse aluminum plates instead of discarding them into a waste receptacle. Also, use closed loop recycling, with off site metal reclamation, for metal etching solutions instead of discarding the metal etching solutions down the drain
  5. Use low or zero-VOC fountain solutions or consider waterless printing operations as well as replace isopropyl alcohol with alcohol substitutes in fountains solutions (avoid glycol ethers that are classified as a Hazardous Air Pollutant
  6. Use low vapor pressure solvents and blanket washes, or water miscible solvents that also have a flashpoint greater than 140 degrees Fahrenheit
  7. Use solvents and blanket washes that contain no hazardous air pollutants such as toluene or 111-trichloroethane. Also, consider the use of automatic blanket washers, and consider on-site reclamation of solvents and blanket washes
  8. Centrifuge shop towels to remove excess solvents prior to laundering
  9. Blend and reuse current ink supplies as in house black, instead of disposing of them in a waste receptacle where they can be considered a hazardous waste
  10. Recycle all waste paper and office paper instead of disposing of them in a waste receptacle
