Re: acrylic plastic sheet P2 question



Helen,
One possible direction, would be to look at possible water borne  formulations that may facilitate both waste reductions of emissions, as well as, assist with recovery(filtration) options. We recently researched some water borne resin options for a manufacturer in Ohio-
Alberdingk Boley-

Resolution Performance Products-

IGM Resins-

The current vendor to the facility may have water borne or higher solids formulations as a starting point.

P2ers, 

I recently had a question from one of our haz waste inspectors regarding P2 opportunities at an acrylic plastic sheet manufacturer .  The sheets are used in optics applications. This manufacturer flow coats the sheet with a resin several times before treating it with UV light.  The flow coat solution is approximately 70% isopropyl alcohol, a small portion of resin, and the remainder of it is PM glycol ether.  They have been re-circulating it and re-using it until it is too contaminated to use.  Then it is disposed of as a hazardous waste.  They are interested in options to extend the re-use of this flow coat.    

The company has looked into distillation but doesn't think it will work with the blended solvents. I believe filtration is an option.  Has anyone else been to a company similar to this and seen other opportunities or specific technologies applied? Thanks
