Bob, You brought up some good questions. That is why the Pollution Prevention Opportunity Assessment (PPOA) is such a good tool. You probably remember the basics of a PPOA from Chicago several years ago. We, the Pollution Prevention Technical Team at Pantex Plant, completed a PPOA prior to purchasing our electrostatic powder painting system. When you are focusing on what chemicals are used and what wastes are generated in a given process, you tend to expand your thought process to those proposed alternatives and their effects on waste generation. I think you bring up a good point that needs to be stressed. Don't box your thoughts in to solve a waste generation problem, only to create another one. Say no to tunnel vision. Good Thought!

Waste powder paints can be in excess of 400 pounds per day for some operations. Some pigments may have metals in them - metallic colors. Except for automotive, most people change colors frequently rendering the recycle option useless. Vendors stress the removal of VOC's from the air and do not tell about the solid and hazardous waste streams that are now created. The solids must be tested for TCLP. How often do we recommend changes without considering the consequences of the alternative? Bob Pojasek rpojasek@sprynet.com
