What is decoating? The Decoating Process is a cutting-edge technology that involves the removal of coatings from scrap aluminum and cans, allowing for the recovery of pristine aluminum and facilitating efficient recycling. This process utilizes advanced techniques to eliminate contaminants, such as paint, lacquer, or plastic coatings, resulting in high-quality aluminum suitable for various applications.

All coatings contain organic or inorganic compounds and very often both. When released by thermal degradation and/or oxidation, they invariably undergo chemical changes as the complex compounds are reduced to their basic form. For example, polypropylene is reduced to carbon monoxide, carbon dioxide, hydrogen, and water vapor.

OVERSIZE SCRAP ALLOWED

• Input size allowed up to 250 mm
• The Decoating Kiln is designed with a special Hengyang shape paddle to optimize the scramble and skim of the scrap and to remove efficiently the totality of the organics presence
• The More The Better! Thanks to the oversize scrap input, the system has a major organics laps effect on the surface and therefore a major organics evaporation (= more natural fuel)
• Less energy consumption in the Shredding phase as there’s no need to “polverize” or heavily reduce the size of the scrap
• Less Natural Gas consumption thanks to the elevated presence of organics in the process
