Dear Patty Vargas,
No, I've never heard of glass sorted by centrifuge. Glass is sorted by hand or by optical wave techniques. The optical wave technologty involves a prism separating the light into its components after it has passed through different colors of glass. The Germans were involved in what they called photoelectronics to sort glass in an MRF. Domestically, the technology was applied by New England CRInc, N. Billerica, MA and by the State of RI. Most MRFs rely on hand sorting; a few on optical sorting.
