Hyperspectral imaging based cascade detection applied to paper, cardboard, plastics and multilayer packaging sorting

Recycling of post-consumer packaging wastes involves a complex chain of activities, usually based on three main stages, that is: i) collection from households or recovery from MSW, ii) sorting and, finally, iii) mechanical recycling. This paper investigate the sorting logics, hyperspectral imaging based, to apply to implement and to set up in order to perform an automatic separation of paper, cardboard, plastics and multilayer packaging.
