Processing technologies addressed to recover plastic from complex waste, characterized by the presence of different polymers and associated contaminants, need to be extremely powerful, simple to be cost-effective, accurate enough to create high-purity raw materials for high-quality products. Considering the boost of environmental regulations and the oil price increase, many industries are interested both in “general purpose” waste sorting technologies, as well as in developing more specialized sensing devices and/or inspection logics for a better quality assessment of plastic products. In this paper new analytical inspection strategies, based on hyperspectral imaging in the near infrared field (1000-1700 nm), have been investigated and set up in order to define quality control logics that could be profitably applied, in “on-line” architectures, at industrial plant level for polyolefins recycling.

Abstract
Processing technologies addressed to recover plastic from complex waste, characterized by the presence of different polymers and associated contaminants, need to be extremely powerful, simple to be cost-effective, accurate enough to create high-purity raw materials for high-quality products. Considering the boost of environmental regulations and the oil price increase, many industries are interested both in “general purpose” waste sorting technologies, as well as in developing more specialized sensing devices and/or inspection logics for a better quality assessment of plastic products. In this paper new analytical inspection strategies, based on hyperspectral imaging in the near infrared field (1000-1700 nm), have been investigated and set up in order to define quality control logics that could be profitably applied, in “on-line” architectures, at industrial plant level for polyolefins recycling.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
