摘要

Materials surface characteristics can be investigated analyzing their spectral response when properly energized by a suitable source. When the energizing source is represented by a light spectra of known characteristics the surface material response can thus be evaluated adopting a spectrophotometric approach. The analyses of the detected spectra can give useful information concerning the investigated material characteristics and/or surface properties and status. This last aspect is utilized in the present study to set-up a procedure aimed at the recognition of glass fragment (cullets) according to their color. The study was particularly addressed to investigate the possibility to apply "real time spectrometry" in the field of glass recycling. In most cases, in fact, glass recycling means to realize a collection and a further processing of glass materials according to its color properties usually resulting from differentiate collection of urban waste. It is thus necessary to select specific and appropriate processing strategies addressed "to clean" glass fragments from all those impurities that can compromise their further re-use both at melting and final product manufacturing stage. Together with "cleaning" an other important aspect, of cullets recycling, is the need to realize a further "selection" of this products according to their destination of use on the bases of their color characteristics. The successful achievement of the previous mentioned goals together with the intrinsic physical-chemical properties of glass permit to reach several positive targets: i) saving of the raw materials necessary for its production; ii) reduction in energy consumption and iii) reduction in the quantity of solid urban waste produced.
