Hinsichtlich der Erschließung der Recyclingpotenziale edel- und sondermetallhaltiger Abfälle aus unterschiedlichen Anfallstellen bestehen derzeit noch verschiedene ungenutzte Potenziale. Mittelfristig soll das Recycling ausgewählter, aus umweltpolitischer Sicht relevanter Edel- und Sondermetalle verbessert werden. Ziel des Vorhabens ist es vor diesem Hintergrund, Vorschläge zur Optimierung und intelligenten Gestaltung der Recyclingkette (von Erfassung bis Rückgewinnung) für komplexe edel- und sondermetallhaltige Abfallströme zu entwickeln. Dazu sind folgende drei Themenfelder zu bearbeiten: 1) Erfassung, Bündelung, 'Intelligente Logistik': Für die Bündelung und selektive Erfassung von auszuwählenden Abfallströmen mit (oft gering konzentrierten) Edel- und Sondermetallen sind qualitativ neuartige Logistikkonzepte und Möglichkeiten zur intelligenten Organisation der Materialströme und Gestaltung der Informationsflüsse zu entwickeln, um das Recycling der Edel- und Sondermetalle sowohl in technischer als auch in wirtschaftlicher Hinsicht zu ermöglichen. 2) Zwischenlagerung: Da für bestimmte edel- und sondermetallhaltige Abfälle bisher keine großtechnischen Behandlungs- bzw. Rückgewinnungsverfahren verfügbar, jedoch in der Entwicklung sind, ist der Ansatz der Zwischenlagerung dieser Abfälle, bis geeignete Recyclingverfahren bzw. -kapazitäten verfügbar sind, zu konkretisieren und zu prüfen. Dabei sind insbesondere auch EU-rechtliche Vorgaben zu berücksichtigen. 3) Behandlung und Recycling: Kriterien für einen ökologisch optimalen Rückgewinnungsgrad aus den Abfallströmen sind zu entwickeln und beispielhaft auf ausgewählte edel- und sondermetallhaltige Abfallströme anzuwenden. Diesem optimalen Grad ist der technisch realisierte bzw. absehbar realisierbare Rückgewinnungsgrad gegenüberzustellen. Es sind Konzepte und Optimierungsvorschläge zu entwickeln und zu bewerten. Die Themenbearbeitung ist durch Fachworkshops zum Informationsaustausch und zur Diskussion von Lösungsansätzen zu unterstützen. Anschließend ist vorzuschlagen, wie sich die zu den drei genannten Themenfeldern entwickelten Konzepte in der Recyclingwirtschaft ggf. implementieren und verankern lassen.

The qualitative and quantitative phase analyses were performed in the KTB field laboratory by x-ray powder diffraction using SIEMENS D 500 diffractometer. During early stages of the KTB project a new method for quantitative phase analysis was developed (see references below). The method is based on the comparison of the diffraction spectrum of the unknown sample with those of pure minerals. The powder diffraction data of the minerals are stored in a database built up of 250 natural minerals separated from various types of igneous and metamorphic rocks. The complete analyses (radiation: Cu K alpha, lambda: 1,5405Å, stepwidth: 0,01°, counting time 2 sec/step, angle 2-80°) was carried out automatically including computations. The results of this quantitative phase analysis were used e.g. to check thin section petrography (and vice versa) and to construct a \"mineralogical rock composition log\".
