A system for sorting a mixed stream of colors and types of cullet into separate groups of cullet with similar color and type includes a source for transmitting light through a cullet, and a camera having a plurality of pixels for receiving light transmitted through the cullet or detecting the absence of light blocked by an opaque contaminant, the camera providing at least one value from the light received, wherein the cullet moves along a designated path based in part on the at least one value. The system further includes a radiation source for irradiating a cullet with selected spectral ranges of radiation, and a sensor for determining characteristics of one or more selected spectral ranges of fluorescent radiation emitted by the cullet, wherein the cullet moves along a designated path based in part on the characteristics of the one or more selected spectral ranges of fluorescent radiation. The camera and the sensor collect the received light at desired sampling intervals and a circuit converts the output of the camera and the sensor into digital representation values. The circuit calculates a non-linear function from the digital representation values. An electrostatic or fluid driving actuator directs the cullet along a deflected path based on a value of the non-linear function. A vibratory feeder provides the cullet onto a conveyer belt having an exit roller of a desired diameter.
