Abstract
A method and system for sorting different colored objects, preferably glass cullets, into separate groups of same colored objects comprising a plurality of sorting devices for receiving an input feed of different colored objects and sorting the different colored objects based on their light transmission properties into a plurality of output feeds, wherein at least one output feed in the plurality of output feeds is a subsequent input feed to one or more sorting devices in the plurality. The one or more sorting devices sort the at least one subsequent input feed into a plurality of further sorted output feeds. At least one of the plurality of sorting devices is a final sorting device, wherein the final sorting device sorts one or more subsequent input feeds into a plurality of final output feeds. The output feeds preferably contain objects of a desired color, undesired objects and flint objects.
