Abstract
This evaluation addressed product quality, waste reduction/pollution prevention and economics in replacing chemical solvent strippers with a bicarbonate of soda blasting technology for removal of paint from aircraft wheels. Because the paint being removed contained hazardous metal constituents, the liquid and solid wastes as well as the cloud of spray generated were evaluated for metal concentrations present and their leachability. Analyses for Cd, Cr, Cu, Pb, Mn, Ni, and Zn were made as well as total metals concentrations, pH, total suspended solids, and oil and grease. The blasting technology is effective for removing paint from aircraft wheels without significant damage to the anodized surface under the paint. In comparison to solvent depainting this technology reduced the amount of hazardous waste generated as well as cost savings due to operating and disposal costs, resulting in a 15% return on investment in about 4 years.
