U.S. use of microorganisms to remove waste aluminium cans

The United States TRA company has found a microorganism in the natural world that can be used to remove trademark paints from aluminum cans.

In the past, when recycling waste aluminum cans for beverages such as beer and fruit juices, the removal of logos and text printed on waste aluminum cans was a nuisance. These colorful trademark pigments, if removed by combustion, will not only pollute the air, but also lose 15% of the metal aluminum; if they are cleaned with organic solutions, they will easily cause fire and damage the health of workers. Now, with this microbiological removal, it can quickly “eat” these pigments. After only half an hour, the colorful logos on the waste aluminum can no longer exist and can be returned to the furnace directly. (Sui Jun)
