1. A system for providing a quantity of cullet having at least two colors of glass from an input stream of recyclable material and non-recyclable material having at least two colors of glass, comprising: a first sortation station for receiving the input stream, and removing from the input stream at least a portion of the non-recyclable material;a first screening apparatus for substantially removing corrugated fiber products from the input stream;a second screening apparatus for substantially removing newspaper from the input stream;an air classifier for receiving glass from the input stream, and extracting at least one of plastic, aluminum and paper elements from the input stream;a third screening apparatus that receives non-glass items and residual glass from said second screening apparatus, and substantially removes paper items from the non-glass items;a second sortation station that receives an output from said third screening apparatus, and directs glass items to a crushing apparatus, and said plastic items to a repository;a crushing apparatus that receives the glass from said air classifier and second sortation station, and breaks substantially all of the glass into pieces having a largest dimension equal to or less than a predetermined length; anda fourth screening apparatus for receiving the crushed glass and removing additional non-glass contaminants, thereby providing as output the cullet comprising at least two colors. 2. The system according to claim 1, wherein the first screening apparatus comprises a disc screen. 3. The system according to claim 1, wherein the second screening apparatus comprises a dual screen separator having an upper screen deck and a lower screen deck. 4. The system according to claim 1, wherein the received non-glass items comprise at least one of: a) plastic items, b) ferrous items, c) non-ferrous items, and d) paper items. 5. The system according to claim 1, further comprising a ferrous separator that receives the ferrous items and the non-ferrous items from said second sortation station, and directs the ferrous items to a repository. 6. The system according to claim 5, further comprising a non-ferrous separator that receives said non-ferrous items from said ferrous separator, and directs said non-ferrous items to a repository. 7. The system according to claim 6, wherein any residual glass provided as output from said non-ferrous separator is provided as input to said crushing apparatus. 8. The system according to claim 1, wherein the second sortation station comprises at least one manual sorter. 9. The system according to claim 1, wherein the first sortation station comprises at least one manual sorter. 10. The system according to claim 1, wherein the non-recyclable material removed at the first sortation station comprises at least one of milk cartons, light bulbs, and styrofoam. 11. The system according to claim 1, wherein the largest dimension is approximately three inches. 12. The system according to claim 1, wherein the largest dimension is approximately two and one-half inches. 13. The system according to claim 1, wherein the at least two colors of cullet comprise one of: a) flint and amber, b) flint and green, b) amber and green, and d) flint, amber and green. 14. The system according to claim 1, further comprising a ceramic detector and remover that receives the cullet from said first screening apparatus, and removes at least a portion of any ceramic from the input.
