REVIEWED P2 OPTIONS
| ||
Reviewed Coating-Surface Preparation OptionsFollowing are a list of options that have been reviewed by pollution prevention specialists. These options have worked at other facilities and may work at yours. |
||
Nonhazardous parts cleaners | ||
| If you are cleaning a part prior to coating it, you might be able to use a nonhazardous parts cleaner. Keep in mind, however, that any parts washing media may ultimately become hazardous due to contaminants picked up from the parts themselves. Whether this happens depends on many factors including: the type of parts being washed, the type of washing medium, and how often the medium is changed. The rate at which material needs to be replaced or becomes hazardous will also depend on whether the parts washers are equipped with self-filtering units that extend the solvent lifetime. | ||
Plastic media blasting | ||
| If you are using sand or another abrasive blasting media, consider switching to a recyclable media like plastic beads. It is gentler than abrasive sand blast systems and will not damage the underlying metal. | ||
Sodium bicarbonate blasting | ||
| The system can replace some harsh chemical processes, be used within delicate environments, and be used on some components that have previously been impossible to clean. After all paint particles or other potentially hazardous materials are filtered out, sodium bicarbonate waste can be discharged to a floor drain that is connected to a conventional wastewater treatment system. | ||
Dry ice (carbon dioxide) blasting | ||
| A dry ice system quickly removes paint and other surface coatings without damaging the item being cleaned and eliminates the use of hazardous solvents. Although it is expensive, dry ice blasting can replace many harsh chemical processes, be used on delicate components, and be used on some equipment that have previously been difficult or impossible to clean. | ||
Install a Proportioner | ||
| Install a proportioner on the spray equipment for plural component coatings such as epoxies and polyurethanes. The proportioner mixes the paint as it is used; therefore, waste associated with unused paint may be reduced. | ||

The Zero Waste Network is a project of the University of Texas at Arlington's Enviornmental Training institute. The tools on this site are presented free of charge to help you find pollution prevention alternatives that work for your facility. They were originally developed throught the support of grant funding from the United States Environmental Protection Agency and contributions from several state, private and non-governmental entities. If you need assistance implementing these options contact us, or enroll in one of our upcoming classes .
