A glass processing system, comprising:
- a conveyor for conveying recyclable material comprising glass;
- an automated sorter, receiving the glass and non-glass material from the conveyor, and separating the non-glass material from the glass;
- an air classifier, receiving the separated glass material and removing any light fraction, wherein light fraction comprises plastic, aluminum or paper materials;
- an automated detector, receiving the separated glass material, and removing any non-glass material;
- an optical recorder for collecting data pertaining to the glass, the optical recorder receiving an input from at least one of the automated sorter, air classifier and optical recorder;
- and
- a controller that receives that data for at least one of adjusting a speed of the conveyor to facilitate system operation, providing composition data to beneficiators, determining composition data of incoming materials or establishing pricing information.
