Method and sorting system for sorting out waste glass cullet with a higher content of iron oxide from a single-layer material stream of waste glass cullet. The material stream contains waste glass cullet with a higher and a lower content of iron oxide. The material stream is irradiated with visible light and the visible transmission light passing through the waste glass cullet is detected, the material stream is irradiated with infrared light in a frequency range of at least 1100-1200 nm and the infrared transmission light passing through the waste glass cullet is detected, a waste glass cullet is classified as having a higher content of iron oxide if the ratio of the intensity of the infrared transmission light to the intensity of the visible transmission light exceeds or falls below a predetermined threshold value, and the cullet classified in this way is separated from other waste glass cullet.

Sorting out waste glass cullet with a higher iron oxide content

The invention relates to a method and an apparatus for detecting leaded pieces of glass in a single-layer material flow of objects composed predominantly of waste glass, with the objects being irradiated with substantially monochromatic UV light () and the fluorescent light resulting therefrom being detected. It is provided therein that
