Compost obtained from different organic waste sources (municipal solid waste, biomass, etc.) is more and more utilized as a relatively low-cost product suitable for agricultural purposes reducing at the same time land filling of wastes. Compost product should comply with specific characteristics in order to be competitive with other fertilizer and amendment products. Main aim of the study was to investigate the possibility offered by hyperspectral imaging to evaluate the compost quality in order to develop control strategies to be implemented at plant scale.

Abstract
Compost obtained from different organic waste sources (municipal solid waste, biomass, etc.) is more and more utilized as a relatively low-cost product suitable for agricultural purposes reducing at the same time land filling of wastes. Compost product should comply with specific characteristics in order to be competitive with other fertilizer and amendment products. Main aim of the study was to investigate the possibility offered by hyperspectral imaging to evaluate the compost quality in order to develop control strategies to be implemented at plant scale. Reflectance spectra of selected compost samples have been acquired in the visible-near infrared field (VIS-NIR): 400-1000 nm. Correlations have been established between physical-chemical characteristics of the compost products and contaminants (glass and plastic particles) and their detected reflectance spectral signature.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
