The Resin Identification Code (RIC) system is a means of sorting different types of plastics from household waste. The RIC was developed by the Society of the Plastics Industry in 1988. The RIC assigns a numeral from 1 to 7, with a “chasing arrows” symbol around the number, to a piece of plastic to indicate its type. SPI recognized the importance of the involvement of the technical stakeholder…, ASTM Committee D20 Next Meeting:, Nov. 14-17, November Committee Week, San Antonio, Texas, Technical Contact:, Thomas Pecorini, Eastman Chemical Co., Kingsport, Tenn., Phone: 423-229-5917; tjpec@eastman.com, ASTM Staff Contact:, Brynn Murphy, Phone: 610-832-9640; bmurphy@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8682/Sept2010
