The Environmental Benefits of Anodizing Process

Aside from producing better quality finish, other important reason why anodizing is considered a promising industry process - particularly in the metal finishing industry - is the fact that it is more environment-friendly than other processes available. This feature is relevant most especially today that climate change issues are a hot topic.

But how exactly can anodizing process be beneficial to the environment? I have listed below some of the benefits as claimed by a number of companies in this industry. These are the following:

• The use of simple water-based chemicals - anodizing is recognized as environment-friendly as it uses simple water-based chemicals that produce no harm to both people and the surroundings. It does not use halogenated hydrocarbons or similar toxic organics in the process.
• An acceleration of a natural oxidation process - this is, in other words, means it does not produce harmful or hazardous by-products and thus ensure no damage to human health or the environment.
• Produces finish that is chemically stable - it will not decompose; it is non-toxic; and, it is heat-resistant to the melting point of aluminum, which is at 1,221 degrees Fahrenheit.
• Produces recyclable liquid by-products - liquid by-products (also known as secondary product produced in the manufacturing process) are recyclable and therefore can be reused/returned to the process.
• Produces harmless primary by-products - by-products such as aluminum hydroxide and aluminum sulfate can be used in other applications. For instance, they can be utilized as filters in the sewage treatment process of sewage treatment plants.
• Solid by-products has other uses - they can have a variety of uses such as in aluminum manufacturing, baking powder, for cosmetics, for newsprint, and as a fertilizer. 
• Emits no ozone-producing solvents - the process does not contribute to the worsening of our ozone layer and there are no heavy metals involved during the process.
• Anodizing as energy-saving catalyst - generally, anodizing is applied to aluminum alloys and this provides energy-saving advantage as well as environment safety. The reason is that Aluminum metal is a good electricity conductor while the anodic coating serves as good insulator. These properties substantially contribute to a product longer lifespan and energy demand reduction.

Above are just few reasons why the anodizing is of real advantage over other metal finishing process. This, indeed, plays a crucial role in the industry,environment-wise -- not to mention the benefits it provides in producing quality finish.
