Recycling to perfection.
Sorting is the most important part of the recycling process. Metallic items are removed from the cullet by magnets. Sieves are used to separate the various size fractions which are then treated independently – a necessity if the automatic treatment process is to be carried out reliably.
Ceramic, porcelain and other minerals are removed in fully automatic sorting machines. In the following stage additional sorting machines are used, this time to separate the various glass colours green, amber and flint. The cullet may be passed through the various sorting stages several times, depending on the level of purity required. Finally, the cullet is suitable for remelting.
