Reducing risk in cullet quality control

摘要

The use of cullet is crucial to a glass manufacturer. It saves money in virgin raw material consumption and about 2 to 3% of melting energy savings can be achieved for each 10% of cullet that replaces primary raw materials, as no reaction energy is required when melting cullet. As carbonates are replaced by cullet, less CO2 waste gases are generated. However, for the glass manufacturer, there's a disadvantage: cullet may contain harmful contamination that disrupts the glass manufacturing process and can generate glass defects. This leads to glass failure and breakage.
