The Environmental Impact Of Anodizing
The Environmental Impact Of Anodizing

The process ,of anodizing, with a ,sulfuric acid, bath produces two byproducts: degraded ,sulfuric acid, and aluminum hydroxide. Aluminum hydroxide is a compound of aluminum from the anodized part, and hydrogen and oxygen from the ,acid,. Classified by the EPA as hazardous, aluminum hydroxide ,wastewater, cannot simply be dumped into a municipal ,wastewater, system.
