Postconsumer plastics packaging waste represents one of the primary source of recovered polymers. One of the main problem now arising is thus the need to certify, in a fast (i.e., online) and reliable way, recovered plastics composition, as well as to assess polymers mixtures bulk characteristics, in order to partially, or totally, reuse them. This paper is addressed to verify the possibility offered by a new technique, hyperspectral imaging (HSI)-based, in order to perform a real-time online… Expand
Comparison of latent variable‐based and artificial intelligence methods for impurity detection in PET recycling from NIR hyperspectral images
In polyethylene terephthalate's (PET)'s recycling processes, separation from polyvinyl chloride (PVC) is of prior relevance due to its toxicity, which degrades the final quality of recycled PET.Expand
Visualizing Polymer Damage Using Hyperspectral Imaging
TLDR
Remote sensing of NCIs using HSI could concentrate on bands below 700 nm to successfully detect in service SIR damage and show how HSI may be used to detect various types of aging damage in different SIR materials. Expand
Plastic waste from recycling centres: Characterisation and evaluation of plastic recyclability.
TLDR
The study demonstrates that detailed characteristics of plastic waste are needed to identify potential challenges to recycling and thereby potentially improving the design (and recovery efficiency) of recycling facilities. Expand
