Apparatus and method for inspecting matter and use thereof for sorting recyclable matter

An apparatus for inspecting recyclable matter, said apparatus comprising:

• a lighting unit for projecting a concentrated diffused lighting onto at least a portion of said recyclable matter to generate a specular reflected light beam representative of the inspected recyclable matter;
• an imaging unit mounted according to a given imaging angle with respect to the projected concentrated diffused lighting for imaging at least a portion of the specular reflected light beam to provide spectral data representative of the inspected recyclable matter;
• an analyzing unit operatively connected to the imaging unit for analyzing the spectral data and providing recyclable matter characterization data based on the at least a portion of the specular reflected light beam representative of the inspected recyclable matter;
• and wherein the specular reflected light beam comprises specular rays selected from a group consisting of specular rays of second surface, specular ray of third surface, specular rays of fourth surface and specular rays of a supporting surface supporting said recyclable matter.
