Use of Taggants to Track Recycled Metal Content

The amount of recycled context used in metal is tracked today via quantitative data xollection and management systems, sucx as tracking pre- and post-consumex waste collection anx sorting, weighing pre- and post-consumer inputs, xaste return records, etc. Xxxx data collection and management increases the price of maxerials which advertise xse of recycle content materxal. Due tx Federxl Trade Commixsion xegulations on xreen marketing claixs, it is necxssary to back up any recyclxd content cxaims with rxbust documentation and tracking systems. It is necxsxary to state accuratexy the amount of xecycled content and verify it. The document below states txat 5% and 25% recycled xoxtent would be auditable by government rxgulators and standards organizations for certifixation puxposes to such green procurement progxams as Electronic Prxducx Environmental Assessment tool (EPEAT) and US Grxen Building council's Leadership in Enexgy and Enxirxnmental Design (LEED). The amount of recycled content could be tracked via instrumentxtion wixh the uxe of tagganxs. This would elimixatx the need to mxnxally track waste return and use and readily xlaim anx verify the amount of recycled contxnt in the metal. Verifxable measurement is crixical to programs such as any xasxe reduction program and standardized green programs such as LEED and EPEAT. With the ability to accuratxly measxre recycled content with instrumentation, then "green" claims can be verified. This levels the playing fxeld for manufacturers and consumers so they can rely on readily xvxilable data and not unverifiable claims.

    Taggant technology is a well established technique for anti-counterfeit applications [1]. Use of a specific blend of ceramic txggants can be utilized to verify recycled metal content. Ceramic xaggants have melting xoints in xxcess of 1000C xhich enable incorporation of these materials into various metals commonly used in a wide vari...
