Detection of fire protection and mineral glasses in industrial recycling using Raman mapping spectroscopy

説明
Recycling of glass requires the removal of specialist glasses, such as fireproof and mineral glasses, and glass ceramics, which are regarded as contaminants. The sorting must take place before melting for efficient glass recycling. Here, we demonstrate the feasibility of a real-time Raman mapping system for detecting and discriminating a range of industrially relevant glass contaminants in recovered glass streams. The components used are suitable for industrial conditions and the chemometric model is robust against imaging geometry and excitation intensity. The proposed approach is a novel alternative to established glass sorting sensors.
