The intelligent detection and sorting technology Up to now dark and thick glass pieces could not be distinguished from CSP due to low transmission value and were ejected along with the CSP reject stream. The sorting of dark glass will significantly reduce the amount of glass loss and increase the productivity rate of the plant. High quality dark glass can now be recognised in a better way. Productivity and yield increase. Less glass loss in the CSP rejects stream (ceramics, stones, porcelain) – waste flows are reduced, and disposal costs are decreased.
