Recycled material waste sorting
X-ray analysis is currently used for the separation of end-of-life materials in the recycling phase, such as metals, glass or plastics.
X-ray machines currently used for metal sorting work both in transmission and in back-scattering: they probe the inspected scrap material and try to identify it, based on its absorption or on the signal emitted by X-ray fluorescence. In this way it is currently possible to separate aluminum from heavier metals such as iron, copper, zinc.
A competitive advantage offered by hyperspectral X-ray technology is the possibility of discriminating different types of aluminum alloys, finding the right compromise between technological advantage and quantity of material inspected per unit of time.
In general, the systems developed by Due2lab could make it possible to separate extremely similar and currently non-separable materials.
