To keep vehicle weights as low as possible, the automotive industry utilises predominantly black plastics. However, they cannot be sorted using traditional methods and are currently utilised thermally.

PROASSORT investigates the use of new, optical sorting methods on black plastics and penetrates into the materials using this method. Chemical characteristics such as the composition of filler materials are recognised and sorted in accordance with specifications. The results allow optimised recompounding of complex-specification primary substances for plastics extrusion.
