Surface Treatments and Coatings

Companies involved in coatings and surface treatments often use chemicals that can easily evaporate into the air. During processes like painting, varnishing, and other surface treatments, solvents release substances into the atmosphere, contributing to pollution.

During surface preparation and coating application, small dust fragments and particles can be generated and released into the air. These particles can vary in size and composition but represent a significant pollutant.

Some industrial processes, such as the combustion of fossil fuels to power furnaces or dryers, can produce nitrogen oxides, particularly nitrogen dioxide.

Moreover, industrial surface treatment and coating activities often involve the use of heavy metals such as hexavalent chromium, lead, or cadmium. These metals can be released into the atmospheric environment in the form of particles or gases, contributing to pollution not only of the air but also of the soil and water.

Industrial practices vary significantly depending on the sector and technologies used; therefore, the types and quantities of pollutants may differ based on the specific process. To mitigate environmental impact, it is crucial to adopt control and filtration measures to prevent harm to the environment and people.
