Editing Anodizing (section)

==Environmental impact==
Anodizing is one of the more environmentally friendly metal finishing processes. Except for organic (aka integral color) anodizing, the by-products contain only small amounts of [[heavy metals]], [[halogen]]s, or [[volatile organic compound]]s. Integral color anodizing produces no VOCs, heavy metals, or halogens as all of the byproducts found in the effluent streams of other processes come from their dyes or plating materials.<ref>{{cite web | title = Anodizing and the environment | url = http://www.anodizing.org/Anodizing/environment.html | access-date = 2008-09-08 | archive-url = https://web.archive.org/web/20080908111117/http://www.anodizing.org/Anodizing/environment.html | archive-date = 8 September 2008 | url-status = dead }}</ref> The most common anodizing effluents, [[aluminium hydroxide]] and [[aluminium sulfate]], are recycled for the manufacturing of alum, baking powder, cosmetics, newsprint and fertilizer or used by [[industrial wastewater treatment]] systems.
