Reviewed Printshops - Image Processing Options
Options below have reviewed by pollution prevention specialists. They are commonly recommended and implemented
for facilities. |
| |
| Protect process baths |
| Protect process baths that spoil easily by keeping them containerized. Small scale photo developers can containerize process baths and use glass marbles to bring the liquid level to the brim each time the liquid is used. |
| |
| Use ammonium thiosulfate |
| Add ammonium thiosulfate to silver-contaminated baths to extend the allowable buildup of silver. |
| |
| Use floating lids on containers |
| Use floating lids on bleach and developer containers to keep them fresh. |
| |
| Install waterless units |
| Install waterless paper and film developing units to minimize the volume of fixer waste. Segregate fixer from developer. |
| |
| Use non-hazardous raw materials |
| Substitute non-hazardous raw materials for hazardous materials whenever possible. |
| |
| Install electronic imaging |
| Install electronic imaging and/or laser plate-making. By editing on a video terminal, then need for photographing and reshooting can be reduced. This alternative may be costly. However, the reduced waste management costs and increased protection of the environment make the investment worth considering. |
