Abstract:
1. Method for recycling materials coming from used objects, comprising an operating sequence comprising the following phases: a preliminary phase in which a classification of the materials to be recycled is carried out, independently of the objects in which these materials are assumed to be present, with allocation, for each of the materials classified, of an identification code, detectable at a distance without contact, a phase of concentration of the materials to be recycled present in the said objects, this phase comprising: grinding of the objects into particles with predetermined dimensions according to the nature of said objects and said components, detection at a distance of each of the particles, identification of the material to be recycled and the extraction of the particles that were the subject of the detection and identification of a marker, and extraction of the particles that were the subject of the detection and identification, and their switching to a specific storage area for the said material to be recycled, wherein: identification code signifies the presence of at least one specific chemical marker, said method comprising a phase of selective chemical marking of the objects, the parts of objects and/or the components of the objects, including the materials to be recycled, in accordance with allocation made according to said classification, detection at a distance comprises detection of chemical markers liable to be carried by each of the particles, identification of the material being made by virtue of the analysis of the marker.
