Analysis report of waste materials of anodized aluminium

Please give me a analysis report of waste materials come out from anodized aluminium. I am a student of Applied Chemistry & Chemical Industry. I want to know which elements come out from the waste material of anodized aluminium.

Shah,

The "anodized aluminum" itself, has no "waste materials", however, if you mean, can the process of anodizing aluminum create any waste materials..then the answer is yes..it does/can. Why don't you earn your degree, and do the research of what it takes to anodize aluminum, figure out what chemicals are used to process.. what, if any heavy metals that may be a "waste" may be present, whether certain parts of the process may be neutrilized, and discharged to the local P.O.T.W. The regulations, and definitions of "waste" vary from country to country .. so what may be a waste here, in the USA, may not be considered a waste in India.
