Consumers embrace the concept of recycling and brand owners want to offer products that respond to such noble aspiration. But, without proper traceability mechanisms, it is hard to confidently claim the amount of recycled material used in a finished good. Incremental cost and limited availability amount of recycled polyethylene terephthalate (rPET) have led to erroneous claims about 2/3 of the time.
This poster will share how a methodology was developed and accredited to accurately identify and quantify rPET. It will share the challenges faced during development, the selection of the chemical marker and the equipment evaluated and utilized to have the most consistent and accurate measurement.
