Last issue I was writing about climate change and hyperspectral imaging, a theme | can continue this issue! Our first article is "Hyperspectral imaging applied to the waste recycling sector" by Giuseppe Bonifazi, Giuseppe Capobianco, Roberta Palmieri and Silvia Serranti from Sapienza University of Rome. They look at two important areas of recycling of waste materials: concrete and plastics. If aggregates are to be recycled from concrete, the presence of pollutants (plastics, foams, brick etc.) and the degree of removal of cement mortar from the aggregates must be assessed and monitored. NIR hyperspectral imaging with PLS does a good job of both tasks.
