Abstract
A method for processing cullet includes detecting a plurality of types of glass contained in the cullet using colorimetry, calculating a quantity of different types of glass detected in the cullet, determining a quantity of oxide and/or a redox potential which are associated with the cullet depending on the quantity of the different types of glass detected in the cullet.
Claims9
A method for processing cullet, comprising:
- detecting a plurality of types of glass contained in the cullet by colorimetry, the detecting involving a first phase of acquiring an acquired image of the cullet, then a second phase of colorimetric processing of said acquired image of the cullet, a surface area covered by each color specific to each of the plurality of types of glass of the cullet being computed as a function of a pixel size of an image acquisition device used for the first phase and of a number of pixels of a pattern corresponding to each of the colors;
- computing an amount of the plurality of types of glass detected in the cullet, and determining an amount of oxide and/or a redox potential associated with the cullet as a function of the amount of the plurality of types of glass detected in the cullet.
