The recovery of materials from DemolitionWaste (DW)
is a significant target of the recycling industry and it is important
to know which materials are present in order to set up efficient
sorting and/or quality control actions. The implementation of an
automatic recognition system of recovered products from End-
Of-Life (EOL) concrete materials can be an useful way to maximize
DW conversion into secondary raw materials. In this paper
a new approach, based on HyperSpectral Imaging (HSI) sensors, is
investigated in order to develop suitable and low cost strategies
finalized to the preliminary detection and characterization of materials
constituting DW flow stream. The described HSI quality
control approach is based on the utilization of a device working
in the near infrared range (1000-1700 nm). Acquired hyperspectral
images were analyzed. Different chemometric methods were
applied. Results showed that it is possible to recognize DW materials
and to distinguish the recycled aggregates from the investigated
contaminants (brick, gypsum, plastic, wood and foam).
