Langhals, Heinz ; Schmid, Tanja; Herman, Markus; Zwiener, Matthias and Hofer, Alexander (2013): Binary Fluorescence Labeling for the Recovery of Polymeric Materials for Recycling. In: International Journal of Environmental Engineering Science and Technology Research, Vol. 1, No. 7: pp. 124-132

Abstract

Fluorescent perylene derivatives for the invisible digital coding of polymers were reported where a binary combination of fluorescent doping allows the unambiguous identification of the polymers for sorting. The mono-material recovery of the polymeric materials is an important prerequisite for the high-performance application of recycled material and was enabled by the application of optical methods.
