Title:
Abstract:	Considering the increasing shortage of resources, the reuse of material excavated from tunnels is the order of the day, which is being followed by clients, consultants and contractors as well as lawmakers. In addition to the creation of a legal situation to enable efficient and unbureaucratic reuse, further technical developments are also required in relation to material analysis to enable an immediate characterisation of the material at the face according to the decisive parameters for reuse. The linking of these results with a raw material database, in which the results of the material analyses are stored, represents a step towards modern, web-based handling of mineral raw materials. Die Wiederverwertung von Tunnelausbruchmaterial ist in Anbetracht zunehmender Rohstoffverknappung ein Gebot der Stunde, das es sowohl von Auftraggebern, Planern und Baufirmen als auch dem Gesetzgeber selbst zu verfolgen gilt. Neben der Schaffung einer rechtlichen Situation, die eine effiziente und unbürokratische Verwertung ermöglicht, sind auch technische Weiterentwicklungen in Bezug auf eine Materialanalyse gefordert, die eine Charakterisierung des Ausbruchmaterials sofort am Anfallort nach den für eine Verwertung entscheidenden Parametern ermöglicht. Die Verknüpfung dieser Resultate mit einer Rohmaterialdatenbank, die mit den Ergebnissen der Materialanalyse gespeist wird, stellt den Schritt zu einem modernen, webbasierten Handel mit mineralischen Rohstoffen dar.
