Impurities from waste plastic, such as food and drink residues, pieces of wood, pieces of fabric and the like, are carbonized into dry and fine coke granules during melting in the EREMA waste plastic recycling section.
All impurities that cannot be carbonized or melted, such as pebbles and sand as well as larger metals, which are tried to be processed with the PWED plant outside of the regulations, are separated in the ash chamber of the EREMA smelter.
