Turnkey bottle-to-bottle plant includes patented friction washing equipment.
PET recycler Mossi & Ghisolfi Group
, based in Tortona, Italy, has selected the Italian equipment company AMUT
to supply a PET bottle recycling plant at its facility in Pocos de Caldas, Minas Gerais, Brazil. The plant is expected to be operational this year and will be able to produce high quality flakes suitable for bottle-to-bottle processes.
The Brazilian plant will have a capacity of two metric tons per hour, AMUT says, and will be used for baled PET bottles collected from municipal sources.
According to AMUT, pollutants contained in the bales are removed by the washing process. Recyclables, including caps, collars, labels and PET, are separated and stored. AMUT says many technologies, developed by the company’s recycling division, are involved in the procedure.
At the core of AMUT’s PET recycling process is its patented friction washer. The machine automatically adjusts the quantity of flakes processed and generates a mechanical friction action that removes pollutants continuously, the company says. The pollutants are removed using a large flow of water and filtered to remove glue, the company says. The result is a high purity final product with a level of organic residues at 20 parts per million.
The washing is performed using minimum quantities of water, the company says (1 litre per every kilogram of PET). The water involved in the process is automatically measured, filtered and reused in various sections of the system.
